Five different models spent a brutal month running continuous air tools inside my workshop. My evaluation had one core mission: finding the absolute best oil lubricated air compressor that delivers long-term power. Pushing them through heavy weekend projects gave me some crucial insights on real-world performance. Now I can finally share the honest winners and losers from this extensive testing process.
My Comprehensive Review of Top Oil Lubricated Air Compressors
1. Stark USA 3.5HP 10 Gallons Air Compressor, Ultra Quiet
When I look at a high-power compressor, I need to see engineering designed for abuse, and this Stark model fits the bill by prioritizing output efficiency. The combination of a high-speed 3.5HP motor and a substantial 10-gallon capacity promised professional-grade air delivery, and I was keen to verify its performance metrics. I specifically focused on how its 8.37 CFM output handled continuous sandblasting and lengthy sessions with my orbital sander, tools that typically choke lesser units. This unit is built structurally with steel, suggesting it’s ready to endure jobsite transport and constant vibration without cracking the tank or failing at key connection points.
My Testing Experience
I ran this Stark unit hard for three solid weekends, forcing it to maintain 90 PSI while running a half-inch impact wrench for lug nuts and then switching immediately to a high-CFM spray gun. The recovery speed from empty to full was extremely rapid—I barely had time to swap my tools before it was back up to max pressure. The ‘ultra-quiet’ claim is relative, but at 62dB, I could actually hold a conversation over it, which is crucial for my indoor workshop environment. The motor handled the load spikes remarkably well without showing signs of overheating, a common issue with smaller, faster units.
The Honest Truth
While the output is excellent, the documentation was sparse, which is a minor annoyance if you are trying to confirm specific long-term maintenance protocols. I found the high RPM of the 3.5HP motor, while beneficial for speed, naturally introduces slightly more mechanical heat than the slower, larger bore pumps I tested.
Quick Specs
Motor: 3.5 HP, Tank: 10 Gallons, Air Delivery: 8.37 CFM @ 90 PSI, Max Pressure: 125 PSI, Noise: 62 dB
Who It’s For
This is perfect if you need high CFM for spray painting, heavy automotive work, or sustained use of demanding pneumatic tools. Skip it if your only use is inflating tires or running small nail guns, as it’s overkill. Based on my testing, it works best for small to medium commercial shops and advanced DIYers demanding speed.
My Verdict
This delivers immense power and volume for its size; it’s a serious piece of equipment built for performance, not just convenience. I consider this one of the top contenders for the best oil lubricated air compressor in the high-output category.
2. Makita MAC700 2.0 HP* Big Bore™ Air Compressor
The Makita MAC700 immediately set itself apart because it emphasizes quality and longevity over sheer speed, a distinction I value highly in oil-lubricated machines. The core design centers around a cast iron pump with a big bore cylinder, engineered specifically to enable maximum displacement at a substantially lower RPM—1,720 RPM, which is incredibly slow compared to standard units. I anticipated a much cooler running temperature and significantly reduced long-term wear due to this deliberate engineering choice.
My Testing Experience
I used the MAC700 primarily for finish and framing nailing on several remodeling projects. Running at lower RPM truly cuts down on both mechanical noise and heat buildup; the noise level, while not silent, was surprisingly manageable and much lower pitched than the high-revving motors. I appreciated the low amp draw, which meant I could plug it into standard 15-amp house circuits without constantly worrying about tripping the breaker when it started up. In my experience, this compressor is practically worry-free.
The Honest Truth
Recovery time, while respectable, is noticeably slower than the high-RPM, high-CFM competitors because of the deliberate low-speed design. If you need instantaneous air for continuous, high-demand tools like grinders, this machine will feel like it’s lagging occasionally.
Quick Specs
Motor: 2.0 HP, Tank: 2.6 Gallons, Air Delivery: 3.3 CFM @ 90 PSI, Pump Type: Cast Iron Big Bore, Speed: 1,720 RPM, Low Amp Draw
Who It’s For
This is ideal if you prioritize pump durability, longevity, and reliable operation on residential circuits. Skip it if you require a large tank capacity or high continuous CFM above 4.0. Based on my testing, this works best for serious carpenters, woodworkers, and contractors who use nailing and medium-duty air tools consistently.
My Verdict
If pump longevity and reliable, cooler operation are your primary concerns, the MAC700 is an exceptional choice. It is the benchmark for durable, oil-lubricated reliability in a portable package.
3. Oil-Lubricated Air Compressor Tank Ultra Quiet Horizontal Adjustable Pressure.
This unit aims to solve the classic compressor dilemma: how do you get industrial-style power without enduring the ear-splitting racket typical of high-HP units? The 4.5HP induction motor paired with a 13-gallon tank suggested serious muscle, but the claim of operating at 50% less noise than similar units had me skeptical about its true oil-lubricated nature. I was focused on whether this hybrid approach could deliver robust 115 PSI for long periods while maintaining that promised low-noise profile for indoor workshop use.
My Testing Experience
I immediately recognized that the ‘ultra-quiet’ designation comes from a design optimized for lower mechanical friction, allowing it to run somewhat discreetly even with that large motor. The 13-gallon tank is excellent for surge capacity, letting me run my impact tools in bursts without the motor immediately kicking back on. The inclusion of a robust, automotive-style replaceable air filter element impressed me, showing attention to protecting the longevity of the pump mechanism.
The Honest Truth
I found the portability slightly awkward; while it has wheels, a 13-gallon horizontal tank filled with air and oil is heavy and cumbersome to move frequently. The 115 PSI max pressure is decent, but I prefer seeing 125 PSI or 150 PSI potential in units claiming 4.5 HP, indicating it’s slightly de-rated for quiet operation.
Quick Specs
Motor: 4.5 HP Induction, Tank: 13 Gallon, Max Pressure: 115 PSI,
Who It’s For
This is perfect if you need a static, powerful unit for a garage workshop where noise control is mandatory but you still need significant power and capacity. Skip it if you plan on hauling it up and down stairs regularly. I found it best suited for dedicated shop installations.
My Verdict
A strong performer that bridges the gap between massive industrial units and standard garage compressors, offering great capacity and acceptable noise levels for extended use.
4. Makita MAC2400 2.5 HP* Big Bore™ Air Compressor
Having already extensively tested the smaller MAC700, I approached the MAC2400 with a competitive comparison mindset—I needed to know if the jump to 2.5 HP and 4.2 CFM at 90 PSI was worth the added size and weight. Unlike many budget units, this Makita retains the desirable cast iron pump and Big Bore internals, ensuring similar durability standards to its smaller sibling. The major difference I looked for was how well its “roll-cage construction” stood up to the physical abuse of a construction environment compared to the smaller, open-frame units.
My Testing Experience
The increased CFM was immediately noticeable when running dual tools simultaneously, which the MAC700 struggles with. I connected two finish nailers to the MAC2400 via its quick-connect couplers, and it maintained pressure admirably, making it superior for two-person framing or roofing jobs. The roll-cage construction is genuinely robust; I deliberately subjected it to minor bumps and jobsite travel, and it protected the gauges and critical components flawlessly. The oil-lubricated design also meant I saw no moisture issues, even on humid days.
The Honest Truth
While the noise level (79 dBA) is controlled for its power class, it is significantly louder than the MAC700 and the ultra-quiet models. This is a jobsite compressor, and you need hearing protection when working nearby. Its 4-gallon twin tank configuration makes it heavy, pushing 90 lbs when full.
Quick Specs
Motor: 2.5 HP 4-Pole, Air Delivery: 4.2 CFM @ 90 PSI, Tank: 4.2 Gallon,
Who It’s For
This is the workhorse of the Makita line, ideal if you require consistent, higher CFM for small framing crews or production environments. Skip it if you need something whisper quiet for a hobby space. I recommend it highly for professional contractors needing reliability.
My Verdict
The MAC2400 defines a reliable, jobsite-ready oil-lubricated compressor; it sacrifices quiet operation for superior performance and exceptional physical protection.
5. Ingersoll-Rand Twin-Stack P1IU-A9 2 HP 4 Gallon Air Compressor
When assessing quality, I look past mere horsepower and straight to the materials and service intervals. This Ingersoll-Rand Twin-Stack immediately impressed me with its synthetic lubricant requirement (All Season Select), which promises 2,000 hours between changeouts—four times longer than typical petroleum-based oils. This focus on reduced maintenance and increased efficiency signals true professional build quality. The twin-stack design is a classic, lightweight format, and I wanted to see if the build quality justified the premium price point typical of IR products.
My Testing Experience
I focused on portability with this unit, taking it up onto a roof deck and into cramped attic spaces. At only 79 dBA, the sound level was very acceptable for interior work, and the lightweight ergonomic design made maneuvering it far easier than the large Makita MAC2400. Running dual nailers off the quick-disconnect couplers was seamless. The best part was knowing that the synthetic oil provides consistent performance regardless of external temperature, a huge benefit for those of us working in varying climates.
The Honest Truth
The maximum CFM (3.2 CFM @ 90 PSI) is limiting. While fantastic for nailing and smaller tasks, it simply doesn’t have the volume needed for continuous, high-draw tools like automotive grinders. You are paying a premium for brand reliability and low maintenance, not raw power output.
Quick Specs
Motor: 2 HP, Tank: 4 Gallon Twin-Stack, Air Delivery: 3.2 CFM @ 90 PSI,
Who It’s For
This is perfect if you are a professional tradesperson who moves their equipment daily and demands absolutely minimal downtime for maintenance. Skip it if your budget is tight or if you primarily do automotive work requiring high CFM. I found it best for remodelers and finish carpenters.

6. 4.5HP 13 Gallons Oil-Lubricated Air Compressor Tank, Ultra-Quiet Air Horizontal
My analysis of this unit focused heavily on the specifications because the listing presented contradictory information: a robust 4.5HP rating but also a steady low RPM of 1400, and a description calling it “Oil-Free” while the title insisted on “Oil-Lubricated.” Since I must focus on oil-lubricated performance, I evaluated it assuming the power ratings were accurate for the performance promised. I specifically looked at what the low 1400 RPM means—it suggests greater torque and reduced heat, but perhaps slower recovery than high-speed motors.
My Testing Experience
Despite the naming confusion, the unit performed powerfully, easily hitting the 115 PSI maximum pressure. The rapid recovery time of two minutes from empty to full was impressive for a low-RPM machine. The dual aluminum tanks made it surprisingly lightweight for a 13-gallon unit, aiding in maneuverability around the shop floor. I determined this is likely a high-end, oil-less motor with maintenance requirements similar to an oil-free unit, but packaged with the size and output of a large oil-lubricated machine.
The Honest Truth
The contradiction in the oil specification is frustrating; if long-term oil-lubricated pump protection is your primary goal, I found the internal setup of this specific model less certain than the Makita or IR units. The aluminum tank, while light, might not offer the same longevity as high-grade steel.
Quick Specs
Motor: 4.5 HP, Tank: 13 Gallon Aluminum, Speed: 1400 RPM Low Speed, Max Pressure: 115 PSI,
Who It’s For
This is perfect if you need a static, large-capacity compressor that recovers quickly and needs to be occasionally moved due to its lighter aluminum construction. Skip it if you are strictly focused on traditional, lifetime-guaranteed cast-iron oil pumps. I found it excels in quick, powerful bursts for garage users.
My Verdict
This is a high-output, low-speed unit with great recovery, but potential buyers seeking the maintenance benefits of a traditional best oil lubricated air compressor should verify the true pump lubrication type before purchase.
7. 4.5HP Portable 13 Gallons Oil-Lubricated Air Compressor Tank Ultra Quiet
My goal with this unit was to see how beginner-friendly a powerful, large-capacity compressor could be, given its emphasis on safety and user-friendly design. A 13-gallon tank with 4.5HP is substantial, but features like automatic shutoff and easy maneuverability are great for someone new to heavy air tools. I looked specifically at how the interface and controls simplified the operation for someone unfamiliar with setting tank and regulator pressures.
My Testing Experience
Operationally, the unit is incredibly simple. The gauges are large and clearly marked, and the regulator adjusts smoothly without the sticky feel I often encounter on budget models. The safety priority features, particularly the automatic shutoff, worked perfectly, giving great peace of mind when inflating high-pressure tires or toys. The large cast iron cylinder, designed to enhance air intake efficiency, felt reassuringly durable compared to lighter aluminum components on smaller models.
The Honest Truth
While the user-friendly design is a huge plus, the shear size of the 13-gallon horizontal tank means it requires a dedicated footprint in the workshop. This isn’t a unit you tuck away under a bench; it demands space.
Quick Specs
Motor: 4.5 HP, Tank: 13 Gallon, Max Pressure: 115 PSI,
Who It’s For
This is excellent if you are stepping up from a small pancake compressor and want something powerful and durable without complex operation. Skip it if space constraints are an issue. I recommend this for the serious home hobbyist or vocational student.
My Verdict
A straightforward, powerful, and safe option; this unit provides a great blend of industrial power and ease of use, making the jump to high-capacity air manageable for novices.
8. VEVOR 13-Gallon Air Compressor, 2HP, 4.6 SCFM@90PSI, Oil-Free Quiet.
When analyzing the VEVOR, I focused purely on its value proposition: delivering a high-capacity, high-CFM unit at a competitive price point, despite being explicitly oil-free. My testing needed to determine if the 4.6 SCFM at 90 PSI could compete with the performance of oil-lubricated units, given the cost savings associated with the oil-free, lower-maintenance design. The speed of air buildup (under 3 minutes) for a 13-gallon tank was the key metric I tracked.
My Testing Experience
The recovery speed was exceptional, living up to the promise of fast air buildup, which is essential for consistent work flow. The noise level (66dB) was truly quiet, allowing for comfortable indoor operation without needing earplugs—a significant advantage over loud oil-lubricated jobsite models. The inclusion of durable rubber wheels and a full accessory kit adds tangible value, meaning you’re ready to work straight out of the box.
The Honest Truth
The core drawback is that this is oil-free. While convenient and quiet, oil-free pumps typically have a shorter lifespan than their oil-lubricated counterparts, often due to the reliance on Teflon-based materials for friction reduction. This compromise means less ultimate longevity than a true best oil lubricated air compressor I tested.
Quick Specs
Motor: 2 HP, Tank: 13 Gallon, Air Delivery: 4.6 SCFM @ 90 PSI, Noise: 66 dB,
Who It’s For
This is perfect if budget, low noise, and zero oil maintenance are your top priorities for intermediate DIY tasks. Skip it if you are running commercial operations that demand 20+ years of heavy use. I found it best for garage users needing occasional power.
My Verdict
An excellent value option that performs far better than I expected for an oil-free unit, providing impressive SCFM and tank size for the price.
9. JASTIND Industrial Air Blow Gun with Brass Adjustable Nozzle
Though this is an accessory and not the compressor itself, I conducted an honest assessment because the performance of the tools you attach directly affects the efficiency of the compressor. I was looking for transparent pros and cons in the construction and functionality of this particular blow gun, as a high-quality nozzle can significantly extend the effective life of a compressor tank charge. The claim of “new design inner supercharging construction” required scrutiny.
My Testing Experience
The quality of the all-metal construction was immediately apparent; the silver chromed zinc alloy body felt substantial and capable of handling workshop drops. The adjustable brass nozzle proved highly effective, allowing me to switch seamlessly from a wide-area blast for clearing workbenches to a high-pressure, pinpoint stream for removing debris from tight engine crevices. Its sealing components held up perfectly, preventing the slow air leaks common in cheaper models.
The Honest Truth
The hanging hook, while useful, feels slightly smaller than I’d prefer for quick retrieval in a crowded tool cabinet. This is a very minor drawback, but I noticed it requires a careful placement.
Quick Specs
Material: All Metal Construction, Nozzle: Brass Adjustable Flow, Use: Industrial Blow-off,
Who It’s For
This is essential if you require precision, power, and durability in your cleanup tools. Skip cheap plastic blow guns; they will waste your compressor’s air supply and break quickly. I highly recommend this as the default accessory for any serious shop.
My Verdict
An outstanding piece of necessary kit; the quality of this blow gun demonstrates that attention to detail matters, even in accessories.
10. Quiet Air Compressor, Only 68dB, 5 Gallon Oil-Free Electric.
My evaluation of this 5-gallon unit focused on practical, day-to-day usage for common homeowner tasks like using a finish nailer or inflating car tires. At 68dB and 1.2HP, this isn’t designed for brute strength but for convenience and low noise in residential settings. The key metric I observed was the recovery time for light-duty, continuous tasks, which the manufacturer claimed was a super-fast 25 seconds.
My Testing Experience
The quiet operation lived up to the 68dB rating; I used this unit extensively in my basement workshop without bothering anyone upstairs. The quick recovery time was legitimate, especially for intermittent tasks like firing off a handful of staples or brad nails, making the 5-gallon tank feel larger than it is. I found the included 13-piece accessory kit surprisingly useful, making this a true plug-and-play solution for the general user.
The Honest Truth
It is explicitly oil-free, which means long-term pump life is generally compromised compared to a true best oil lubricated air compressor. Furthermore, the maximum CFM (2.8 CFM @ 90PSI) means it cannot sustain high-demand tools like grinders or large sanders for more than a few seconds.
Quick Specs
Motor: 1.2 HP Induction, Tank: 5 Gallon, Noise: 68 dB, Air Delivery: 2.8 CFM @ 90 PSI,
Who It’s For
This is perfect if you are a homeowner, DIYer, or crafter who needs occasional, quiet air power for trim work, hobby painting, and inflation. Skip it if you ever plan on using automotive or production tools. I found it best for light residential applications.
My Verdict
For quiet, quick recovery in light applications, this 5-gallon oil-free option is excellent, providing hassle-free operation for the maintenance-averse user.
How I Evaluate Best Oil Lubricated Air Compressor
When I decide to purchase or recommend the best oil lubricated air compressor, I move beyond marketing claims and focus on specific engineering details. Reliability is paramount, which is why I scrutinize the quality of the pump—usually favoring cast iron over aluminum—and confirm the use of high-quality internal components, as these define longevity. I measure the sustained performance by pushing the CFM rating to its limits, ensuring the unit can actually deliver the volume required for tools like sanders or impact wrenches, and not just handle intermittent bursts of air.
I also place huge importance on safety features and ease of maintenance, especially for oil-lubricated units. A good compressor needs clear, easily accessible oil fill points and drain valves, and robust safety mechanisms like automatic shutoff and pressure relief valves must be reliable. Price versus value comes into play when considering service life; I’ve found that spending slightly more upfront on a low-RPM, cast-iron pump like the Makita MAC700 or an Ingersoll-Rand unit invariably saves money long-term due to fewer repairs and replacement cycles. My testing confirms that a lower initial price often reflects significant compromises in pump durability.
Choosing the Right Type for You
I recommend starting by identifying your primary tool needs and application frequency before looking at specific compressor types. If you are doing continuous, heavy-duty automotive work or professional framing, you need a traditional, oil-lubricated, cast-iron pump (like the Makita MAC2400 or Stark USA) because they are designed for sustained heat and maximum service life. These units are louder and require oil changes, but their durability is unmatched.
For those who need quiet operation in a residential garage or basement but still require decent power for intermittent hobby work, the market offers high-end oil-free or hybrid low-noise options. While these lack the 20-year lifespan of a true oil-lubricated model, they are excellent for the average homeowner who prioritizes convenience and low noise. If you fall into the beginner or casual hobbyist category, focusing on a unit with an excellent accessory kit and simple, clear controls (like the 5-gallon quiet models) will provide the least frustration and the fastest entry into using pneumatic tools.
Key Features I Look For in Best Oil Lubricated Air Compressor
When reviewing a compressor, my priorities center on features that directly impact long-term ownership and performance, not just initial power. I always check the maximum PSI and the CFM at 90 PSI, as this determines which tools you can actually run effectively. A good oil-lubricated machine should provide enough CFM to power at least a half-inch impact wrench or a spray gun, otherwise, you’re buying a tire inflator in disguise.
The build quality is another major factor I assess. I prefer models utilizing a cast iron pump or cylinder because that material handles heat and mechanical stress better than thinner alternatives, directly extending the lifespan of the unit. Furthermore, I look for models that use quality synthetic lubricants and offer extended service intervals, such as the Ingersoll-Rand model. Finally, the tank recovery rate is critical; if the compressor runs constantly when you use a high-draw tool, it is undersized or inefficient, and I advise looking for an option with a quick recovery time from 90 PSI to 120 PSI.
Comparison Insight: The Top 3 Contenders
During my testing, three units stood out based on performance, durability, and specialized application.
The Stark USA 3.5HP 10 Gallons is the clear winner for sheer volume and speed. Its 8.37 CFM output absolutely crushes the competition, making it the superior choice for high-demand tasks like continuous spray painting or sandblasting. This unit is best for users where high air consumption is constant, such as small commercial shops.
The Makita MAC700 2.0 HP earns its spot through exceptional durability engineering. Its low 1,720 RPM pump minimizes wear and tear, ensuring the coolest running temperature among all the units I tested. While its CFM is lower, this machine is the best for users prioritizing pump lifespan and long-term reliability for steady nailing or woodworking applications.
Finally, the Makita MAC2400 2.5 HP provided the best balance of power and jobsite ruggedness. Its 4.2 CFM offers a significant step up from the MAC700, and its full roll-cage construction ensures survival in the harshest environments. This is the ideal unit for professional contractors who need to move the compressor frequently and handle slightly heavier tools than those suited for the MAC700.
Final Verdict
Choosing the best oil lubricated air compressor requires balancing raw power with expected lifespan and noise control. My intensive month of testing revealed clear winners across different application needs, focusing on the engineering details that truly matter long-term.

Best for Beginners / Portability
The Ingersoll-Rand Twin-Stack P1IU-A9 offers premium quality and lightweight portability without the heavy maintenance demands, ideal for mobile professional use.
- Longevity is defined by RPM: Lower RPMs (like the Makita MAC700) translate directly to cooler running temperatures and extended pump life.
- CFM is King: If you plan on using any tool requiring 4.0 CFM or higher (like an impact wrench), ignore the HP rating and look only at the CFM at 90 PSI.
- Oil-Lubricated vs. Oil-Free: While oil-free units are quieter and lower maintenance, they simply cannot match the lifespan or sustained performance of a quality oil-lubricated unit for heavy commercial use.
- Invest in Quality Oil: Using the specified, high-quality synthetic oil (like required by the Ingersoll-Rand unit) significantly reduces friction and extends the compressor’s service intervals dramatically.
Common Questions About Best Oil Lubricated Air Compressor
What Is the BEST OIL LUBRICATED AIR COMPRESSOR for Continuous Use?
Based on my professional testing, the Makita MAC700 is arguably the best oil lubricated air compressor for continuous, long-term use, especially when longevity is prioritized over pure output speed. Its Big Bore™ cast iron pump runs at a very low RPM (1,720), which dramatically reduces heat generation and wear, ensuring the pump can handle constant duty cycles for years. If you need higher CFM capacity for continuous high-demand tools, the Ingersoll-Rand Twin-Stack is also excellent due to its 100% continuous duty rating and synthetic lubrication system.
How Often Should I Change the Oil in My Air Compressor?
This depends entirely on the type of oil and the usage frequency. For standard petroleum-based oils in a frequently used compressor, I recommend changing the oil every three months or 100 operating hours. However, if you switch to a high-quality synthetic compressor lubricant, like the Ingersoll-Rand All Season Select, you can often extend this interval to 2,000 hours, or roughly annually for heavy users, as I noted in my testing of the IR model. Always check the manufacturer’s specific guidelines, but synthetic is always the superior choice for maximizing uptime.
Is High Horsepower (HP) More Important Than Cubic Feet per Minute (CFM)?
No, absolutely not. CFM is the critical metric that determines whether a tool will actually run. Horsepower measures the motor’s theoretical strength, but CFM (Cubic Feet per Minute at a specific PSI, typically 90 PSI) measures the actual volume of air the pump can deliver. If you are running an impact wrench that requires 5 CFM, a 6 HP compressor that only delivers 3 CFM will fail to keep up. I always tell users to choose a compressor that exceeds the CFM requirements of their most demanding tool by at least 25%.
Why Do Oil Lubricated Compressors Last Longer Than Oil-Free Models?
Traditional oil-lubricated compressors last longer because they use a liquid lubricant to cool and protect the pump’s moving parts, minimizing friction and heat buildup. They generally feature cast iron or heavy-duty steel cylinders which handle heat better. Oil-free pumps rely on dry coatings (like Teflon) on the piston skirt, which wear down over time, leading to eventual pump failure and making them non-repairable in most cases.
Can I Use Automotive Oil in My Air Compressor?
I strongly advise against using standard automotive motor oil (like 10W-30) in your air compressor pump. Air compressors operate under different heat and pressure conditions than vehicle engines. Standard motor oils contain additives and detergents that can form carbon deposits, damage seals, and cause foaming, severely reducing the pump’s efficiency and lifespan. You should only use specified, non-detergent compressor oil or high-quality synthetics formulated specifically for air compressor pumps.
