The BEST Warranty In the Industry
Polar Air, by Eaton Compressor, backs all of our piston air compressors with the best warranty in the industry – a full 5 years – and it is NOT pro-rated. Make sure to research and ask questions, when comparing warranty information. Be certain, when you buy, that you are getting a FULL warranty. A Pro-Rated warranty means that, the older the compressor gets, the more risk that you may have to pay out of your own pocket, should it need repair. With our warranty, we don’t ask you to buy a service plan, or extended warranty – we just ask that you purchase and use our oil and filters. This ensures the correct oil and filters to keep your piston air compressor running for years to come. Our trained service and support team is ready to assist you, if you ever need them and we carry a full line of air compressor replacement parts.

Our Air Compressor Pump
At the core of our Whisper Series Quiet Air Compressors is our sturdy and reliable air compressor pump by Eaton Compressor. These air compressor pumps are exceptionally quiet in operation and engineered to provide years of reliable service.
Our air compressor pumps are engineered with reliability and durability in mind. The crankcase is solid cast iron, ensuring stable crankshaft alignment and the ability to handle a higher workload even under heavy load conditions. Our compressor pumps also feature a precision balanced solid cast iron crankshaft with Timken-Style stainless steel roller bearings on the front and rear of the crankshaft, ensuring smooth & efficient operation with less drag and reduced energy usage
Our air compressor pumps also feature:
- All steel connecting rods with replaceable rod bearing inserts – this allows the air compressor rods to be rebuilt. While many of our competitors use less reliable aluminum rods, that cannot be rebuilt, the ability to rebuild the rods in our compressor will save you money.
- Removable 100% cast iron cylinders – our solid cast iron cylinders are more stable under extreme workloads and do not warp from heat, ensuring years of reliable service. Many lesser quality competitors use aluminum cylinders with a pressed-in sleeve, that can quickly warp and often need to be replaced within 1-2 years. Our solid cast iron cylinders were designed to provide years of dependable service under extreme conditions.
- All cast iron cylinder heads – cast iron cylinder heads are more durable and dependable for trouble free operation.
- Disc valve design intake and exhaust valves – disc valves have been around for over 100 years and have been proven to provide reliable service under extreme conditions. Our disc valves can be easily removed from the top of the cylinder head, where they can be serviced in minutes, instead of hours, like the reed valves often found in lesser quality air compressors.
- Top quality compression and oil rings – our rings ensure performance with low oil carry over (1-5 PPM).
- Precision ground pistons – machined to tight tolerances ensuring low oil carry over.
- Premium non-absorbent gaskets – prevent oil seepage from the pump.
- All cast iron flywheel with built-in fan – the extra weight of our cast iron flywheel during run cycle gives the pump more “throw” on the compression stroke resulting in fewer loads on the electric motor. Many lesser quality air compressors use aluminum flywheels that do not have the proper weight ratio to give the proper throw, on the compression stroke, when the pump is running.
- Built-in head unloaders – these unloaders are built into the intake valve assembly, on the compressor head, and perform a valuable function by unloading or opening the intake valves under constant run applications. This feature reduces internal pump heat from compression, because the intake valve is held open throughout the unloading cycle, allowing fresh air to come into the cylinder chamber. Under the compression stroke, the unloader holds the intake valve open, allowing the air to blow back out the intake filter. This fresh air absorbs the heat from the pump under heavy workloads.
- Built-in inter-cooler and after-coolers – the inter-cooler allows air to be cooled between stages, while the after-cooler provides a second cooling stage, that further cools the air before it goes into the tank. Our after-cooler also includes an all copper main feed line from the pump into the tank.
In summary, not only do we have one of the highest-quality, most durable air compressor pumps in the industry, we can also boast the lowest RPM air compressor pumps on the market. On the majority of our compressors, we purposefully oversize our pumps, running them at lower RPMs than most manufacturers. Our more powerful, low RPM pump can still yield a high CFM output, because both our bore and stroke are larger. The benefit is that our customers get the big CFM output, while enjoying the lower RPM operation, which reduces friction and heat, extending the life of the air compressor pump.
Name Brand Electric Motor
These units have name brand OPD (open drip motors) on them, all of which carry a five-year warranty. All of our motors are low RPM (1750 rpm), versus the higher RPM motors (3450 RPM) used on many competitive units. 1750 RPM motors run much cooler than 3450 RPM motors, because of the higher torque factor. They also yield low harmonic distortion, provide much higher torque in cold weather starting and requiring less electricity under start up.
Additional Motor Features:
- Large 1-3/8” output shaft
- High quality ball bearings on the front and rear of the motor shaft
- Large starting and running capacitors15 Service Factor load. This means the motor can be pulled 15% over full load for more break horsepower
- Dynamically balanced armature for low vibration levels
Belt Guard
Built with 13 G steel and premium-grade expanded metal, our belt guards are more dependable and reliable than any of our competitors, in addition to providing exceptional safety for our customers. Built in the United States, all of our belt guards are OSHA approved.
Air Tank
All of our air tanks are manufactured in the United States and are ASME code compliant in 50 states, including California.
Controls & Components
Eaton Compressor uses only top-quality, brand-name components on our air compressors, including:
- Top quality pressure switches – including an adjustable screw, which allows you to adjust your pressure higher or lower.
- 100% brass check valves with Teflon seating – All check valves on our compressors are solid brass with a Teflon seating. This reduces tank noise, when the compressor is running, because the Teflon seating is much quieter than other materials and insulates noise when valves are opening and closing, during the compression stage.
- 100% brass ASME safety valves – all safety valves are 100% brass and comply to ASME code. Valves are preset and sealed for correct settings. In the event that your compressor will not turn off, our safety valves open, keeping the compressor from building too high of a pressure level in the tank. This will help to avoid the potential of tank rupture.
- Top quality plumbing fittings – to maintain proper sealing when connected to the tank.
- High quality 100% brass ball valves – used for turning air on and off from the air receiver.
- Extended tank water drain pipe – plumbed out the front of the unit with a ¼” ball valve handle for easy tank draining. This eliminates the hassle of draining the tank with the typical petcock-style drain under the tank.
- Load-less starting – built-in head un-loaders, in the intake valve assembly, unload the pump so it will not start under direct head pressure. This feature prevents damage to the motor during the starting cycle.
Motor Pulley & Belts
We use taper-lock style, 2-groove pulleys, versus single groove. We also use dual, 2-groove, B-Style belts to drive our pumps. This combination is best for a couple of reasons – the dual belts ensure long belt life, and yield low vibration, which makes for smoother, more quiet operation. This is because the dual belts do not have to be as tight as with a single belt setup. The tighter the belts (as with a single belt setup) the more load on the compressor pump, and motor bearings, which decreases the life of both. As well, our taper lock pulleys are much better than a fixed bore pulley with a set screw. A taper lock design will lock the pulley into position, to the motor shaft, allowing it not to loosen or move on the motor shaft.

Eaton Compressor is one of the easiest and finest companies to deal with that I have EVER encountered, and Steve Derr is by far the most helpful & cooperative individual you will ever speak to. I had SEVERAL situations that needed advice & assistance concerning a compressor for a spray foam insulation business and NOT ONCE did Steve brush me off, he simply told it like it was and buckled down and HELPED!! He has responded to EVERY call and EVERY email, NEVER made excuses and offered a suggestion or solution EVERY TIME. Not only are the compressors head and shoulders above the rest, the help is top not as well. BUY FROM THIS COMPANY!! You won’t be sorry.
This company ROCKS!!! awesome customer service I had my 7.5 hp compressor for 2 1/2 years then the pump developed a problem keeping up with my sandblasting I called Steve and we agreed it was a bad intake valve so he sent me one had it in two days installed it but it did not fix the problem. I called Steve again and he without hesitation sent me a brand new pump and also allowed me to upgrade to the 10 hp v-4 pump had it in two days again! the level of customer service you get with Eaton Compressor is unheard of from any company I have ever dealt with and much appreciated! A friend of mine just bought a 7.5 hp 80 gallon Eaton based on my recommendation from before I had the problem with mine and I will tell everyone else I know to buy Eaton and I will never buy anything else!
thank you again Steve and Eaton Compressor. Matt you have great people working for you!

I bought a 7 1/2 HP compressor from you back in May of 02 to use in my auto repair shop. It has been used daily since then, sometimes quite extensively. It has NEVER missed a lick. We have changed oil and filters on it, and adjusted the belts…that’s it. Compared to the IR unit setting next to it (a backup I’ve never needed)it is quieter, slower and smoother running, just an all around better product. We need to move up to a rotary screw here before long, and believe me when I say there’s only one place it will come from. Thank You.
great compressor 0 to 150 psi in under 2.0 min no lie. low noise saved me almost 100.00 bucks a month on electric bill on a 6 bay auto repair shop had a 2 stage 5 hp 2 cly. before very happy would buy from any time thanks guys Gregg dupuis dupys service center
I’m a little late sending the reviews on my new 7.5 hp Eaton Compressor , but it gave just a lot more time to review the great performance that it has given me in the last 3 months, the air delivery is superior, the pressure is like Matt explained I would receive and all the things that were conveyed to me in my ordering process were delivered as promised. The shipping was on time with in the quoted dates, all extra’s were sent and startup was a breeze. It is a great feeling after spending a considerable amount of hard earned money that the product is delivered on time, complete, and below any of the competitors prices.
also: A good friend took my advice and bought a similar compressor and loves it Now that’s a good feeling.
Thanks for the Honesty and Great Service

I have a custom auto body shop, I bought a 7hp, 80 gal Single Phase compressor from Matt Cain about five years ago. I bought it off of ebay, I was skeptical about buying one off of eBay, although I shopped around for about three months before i bought one. I called Matt and he answered all my questions before i bought it.
When I got it, just like everyone say’s it was packed to be shipped to the moon. when it came time to wire it in, I had some questions, and Matt was there. I think i called him about four times and every time, he answered my questions. He never made me feel like it was any trouble to call.
About two years ago, I had a motor issue, one day opened the shop and fired up the compressor and noting! it was dead, So i got my paperwork out, and called Matt. I thought okay I’m going to be spending a couple thousand dollars. We talked for a little while, and he remembered selling me the compressor.
The best part, was when he told me that they would ship me a new motor, at no cost to me.
I thought to myself, this guy is the real deal! I had kept my old Inger Ran compressor to use as spare air tank, we fired it up, and my body guys where not happy.
Well when the new motor came, there was an issue with the wiring of the motor. Once again Matt came through and fixed the issue.
After that, it doesn’t miss a beat! It has been running for Five Years, everyday at least 8 hours a day. I figured that we have painted somewhere around 500 plus cars.
I change the oil in it every two months, i switched over to Royal Purple Syn Air Compressor oil and NEVER have a water issue.
I have recommended these guys, to at least four of my fellow shop owners.
Way to go Matt and someday i hope to shake your hand, you make a fine product and stand behind what you sell, not only in product but service!
The compressor is great! No problems. Very quiet compared to several others we have owned.
It’s been great! Thank you again! Best one I ever bought hands down!
Waited two years after purchase to write the review on my 7.5 HP 80 Gal Polar Air compressor. Compared to other brands this machine is just built heavier and very well made. Another big surprise after I installed the unit was how quiet it operates compared to similar models from other manufacturers. I expect this piece of equipment will outlast me! I wouldn’t hesitate to recommend it to all my friends and associates. Thanks for building a great piece of equipment!
Thanks for the great customer service!
AWESOME COMPRESSOR, EXCELLENT BUILD QUALITY, GREAT SERVICE, QUIET, POWERFUL
so far so good, real quiet and fast.
Seems like a heck of a compressor and a very good deal so far! Thanks
They will work with you on any issue!
Bought this compressor a little over a year ago and it’s been nothing but pure awesome. Runs my shop air and my cnc plasma table with ease. Problem-free. =)
i have had this compressor now for 10 years. it gets used all day 6-7 days a week in a paint shop. still running strong.
Well packaged, quiet running unit. Time will tell how well it holds up in service.
Bought this compressor a couple months ago to replace a smaller industrial compressor. Using it in my personal shop for not just air tools but also my sandblasting cabinet, painting and winterizing my sprinkler system. I could have bought another industrial compressor brand manufactured locally but during my research I found the Eaton Compressor was actually engineered better. The biggest differences were the pump design and motor used. Extremely quiet and in fact is quieter than the smaller industrial compressor it is replacing.
Had a small problem at first with a pressure release valve opening prematurely. I called and talked to Megan and the tech to resolve my issue. Megan and the tech guy made it a no hassle issue, sent me the parts and took great care of me.
I’d highly recommend the Eaton Polar Air compressors.
Very nice looking compressor. Hope it is a long lasting relationship !!!!
From order to receipt good experience, after install the electronic auto drain would not work Megan immediately sent a replacement and the compressor has been running with no problems and a whole lot quieter than the IR we were using.
Very pleasant, Eaton went above and beyond to get my compressor to me on time! Awesome customer service!
Everything has been good. Great customer service and quick to respond to questions.
Eaton Compressors surpassed my expectations with the quality equipment that we ordered. From the shipping and crating of the units to the sound levels in the shop once up and running. They supply enough air to run everything in the shop with ease. With regular maintenance this unit should last us a very long time.
Thanks Eaton for making a great American Made product!

This compressor is fantastic. Pretty quiet, plenty of air pressure. Couldn’t be happier. Very well built!
I picked up my compressor at the factory. The people you have working for you and 1 of the owners , can’t say enough good things about them. The compressor is unreal, endless air. Thanks
The other shops around me are really shocked on how quiet it is compared to their snap-on compressors same size. the compressor does what it needs to do, supply air. its going to be used for painting and running sanders and so far I like it. I am a one man shop so I won’t be using it to its fully potential. customer service was great while I was ordering it, helped me every step of the way, very well built, its a bargain.
Megan was a great help and knowledgeable. When my new air compressor arrived I was shocked by how well it was packaged. After unloading I was able to get it hooked up and running in about 3 hours. This thing is a beast compared to my Snap-On air compressor. I do a lot of sandblasting in a medium size cabinet. Use to I would have to sandblast for about 3-4 minutes and wait for 20 for the air compressor to catch up. With this compressor, I literally had to go and shut it off because it was going faster than I could sandblast. I could not be HAPPIER!!! The time this will save me will be a money maker.
Great compressor. Quiet and efficient.
So far the compressor is great. It is unexpectedly quiet and looks well built and sturdy
