Riser
Our pump mounting plate riser is designed to raise the pump allowing 360-degree air flow from the flywheel to cool the pump oil reservoir. Pump mount risers also allow air to flow under the pump for maximum cooling.
Continuous Run/Dual Control
Dual Control
Dual control allows users to run the unit with automatic start/stop control, or the optional continuous run setting during high duty cycle peak demand periods.
Optional Settings
The optional continuous run setting allows the pump to cool internally and save the electric motor and magnetic switch from excessive frequent starting and stopping of the electric motor.
Pressure Lube
Pressure Lubrication is the second type of lubrication systems. This system is more technically advanced and a far more precise method to deliver oil to critical parts of the pump, resulting in longer pump life. The oil is pumped through an oil filter and into the pump where it is then recycled and reused. Since the oil pump is delivering the oil more efficiently the viscosity of the oil is less critical than with a splash system. In the air compressor industry, it is typically more costly to upgrade to pressure lubrication systems. *Our high efficiency manufacturing facility 0to the tank. With this radiator, we target outlet air to the tank within 10 degrees of ambient temperature.

Silent Air
Noise Reduction
Our Patented Silent Air system works by dissipating compressor intake noise through a series of noise cancellation plates, reducing DBA ratings by up to 50%. Silent air compressors operate at a normal conversation level in comparison to traditional compressors that operate at the level of a police siren.
Air Filtration
This low-profile system not only makes the compressor quieter but also adds four levels of air filtration.
Silent Air Technology
- Significantly lowers the risk of hearing damage
- Decrease in employee turnover
- Enhances workplace satisfaction
Tensioner
Piston
Piston compressors come optional with a belt tensioner. This belt tensioner allows you to easily and quickly tighten your belts. These tensioners also have a double bolt tension device that allows you to keep the belts in perfect alignment. No pry bars needed to tighten your belts!
Rotary
All Rotary Screw belt driven models 5HP – 20HP include an automatic spring-loaded belt tensioning device. This keeps a steady pressure for optimal belt tension.
Auto Drain
Operation
A dual timer electric auto drain is a device designed to expel moisture and water from the air receiver tank.
Interval Setting Feature
It has an adjustable interval setting feature that allows you to set the device from 1 to 45-minute drain cycles. You can also set the timing of how long you want the drain to stay open.
Muffler Included
Our premium series compressors Include an air muffler for quiet dispensing of water.

Piston Compressor Warranty
Eaton Compressor, backs all our piston air compressors with the best extended warranty in the industry. With our extended warranty, we don’t ask you to buy a service plan, we just ask that you purchase and use our oil and filters. This ensures the correct oil and filters are being used, to keep your piston air compressor running for years to come. We have 3 different extended warranty options to choose from so you can pick what best suits your company’s needs. Make sure to research and ask questions, when comparing warranty information. Be certain, when you buy, that you are getting a full warranty. 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.
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.
- 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

P.DiGinto –
We looked long for an american made/assembled compressor. I have to say this met our expectation times 10. The quality is hands down perfect. This is the quietest compressor i have ever heard with the silent air feature. It got to 175psi in less than 2 minutes. We can literally stand next to this thing and have a normal conversation. Wish i would have bought it sooner. We ordered around the holidays and it was here in 3 weeks. Cant say enough good things about polar air. Thankyou

Martin Friesen –
I bought one of these with the silencer and it is truly amazing how quiet it runs, we can stand beside the unit and still carry on a conversation when the compressor cuts in. It is a well built compressor. It handles my little 10 gallon sandblaster with ease. The continuous run option is also a worthwhile option for times of heavy air consumption

“After exhaustive internet search I chose Polar Air. Complete pleasure to deal with Matt and his team at Polar Air, from the web site, to questions on the phone, to taking the order to shipping to delivery to electrical questions during installation. Since I am not an electrician, but had to hire an electrician and they responded right away to his questions while he was on site. They were on time, a great price and a quality product. The combination of low RPM and the Whisper intake sound muffling unit work even better than I expected. This baby is QUIET! HAPPY that Matt is serving so many American families by having his employees manufacture the Tank, and assembling the motor and pump right here in the USA.” Factory direct is truly the way to go. Thanks Matt for cutting out the middle man and being available directly to the consumer. You saved me a lot of money for such a quality product

You would not believe the attention this air compressor has been generating. I have had people in the neighborhood as well as from where I work come by to see it; all of which have been amazed. Many of the people that have heard about it but have not been able to come by and see ask to see pictures. It has been more of a conversational piece than some of my cars…

Great compressor, wish I had pulled the trigger earlier. Quiet, and relatively vibe-free. Bolted down with backed off anchors and rubber pads. I added an aftercooler ( BGA-100) with an auto drain. Clean dry air in the tank and the system. Only had to fix an auto drain thread leak. You get 80% of a quincy, for 30% of the price, and 1 tenth the noise of an IR. Very happy here- runs anything I have and still cycles.

Megan worked with me in a very friendly and professional manner to complete the transaction. Once the order was placed I had the unit within 1 week! It is the quietest, most powerful air compressor I have ever seen or used. It really looks beautiful sitting in the corner of our Sawdust Santas charity shop and I know it will more than deliver our needs for decades to come.

I seen the compressor at the PRI show in Indianapolis Indiana. I dealt with Matt Cain to purchase 2 units and then with Megan South to pay for and arrange the delivery. I could not be happier with the entire process and both compressors were delivered exactly as promised. At this time i have not installed neither compressor but hope to very soon .Thanks

David Chiappe –
Wow! This compressor is awesome! I’ve had a 7.5 hp “professional grade” big box store brand (sounds something like Ingelbert Randy) for the last 15 years. Talk about an upgrade. Everything is 2-3 times the size. The motor is monstrous as are the castings the pumps is made of. I do a lot of sandblasting and metal refinishing. This thing doesn’t even break a sweat keeping up with the demands I put on it. As far as quiet goes, it is a lot quieter. It’s a combination of running at a much slower speed than most other compressors and the frequency of the sound. It’s much lower frequency and not as piercing as my old compressor. The fit and finish looks great. It was packed very well on an oak pallet with and OSB and cardboard box around it. It’s taken me about a year to pull the trigger on this and I’m glad I did.

PRI Show in Indy, I was impressed with the quietness and quality of the compressor and purchased one for my fab shop. Will be expressing interest on a dryer for it. In process of putting together a CNC plasma table.

Worked with Todd DeLong at the PRI show in Indianapolis and he had an extensive knowledge of your product. I was interested in your air compressor mostly due to the quiet, noise suppression system. I have a hobby shop that I do anything from welding and fabrication to body work and paint. I use the air compressor for multiple applications and so far, your compressor has filled my needs as promised. I would recommend this air compressor to anyone interested in hearing about my experience.

Just got time to wire up my new 7 1/2 HP air compressor with the noise suppressor whisper 100 from polar air. Flipped switch and about died, this compressor is so quiet. AMAZING There is no way to explain how quiet this thing is compared to my old one . I won’t trash my old one it done it’s job but this new one by polar is just absolutely AMAZING l called all my friends to let them here it over the phone.My old compressor was sold by a major tool company and it would almost run you out of the garage when it ran. My neighbors are going to love this Come warm weather when I have doors open. Ok enough about how AMAZING the compressor is now the sales staff at polar air is Awesome. Megan is just absolutely perfect She is very knowledgeable of equipment and what it will take to run your shop . If you are interested in getting a new compressor I strongly recommend polar air staff and product is simply AMAZING. Can’t wait for a big job to put it through the paces. Thanks Polar Air .

This unit is Awesome! 7.5 hp whisper with after cooler radiator. Shipping company damaged crate pretty bad but all inside was still undamaged! I got it hooked up last night and fired her up. A neighbor and I were having a normal conversation while standing right in front of the running compressor. She pumped up and shut off in crazy short period of time. Best money I have spent in a long time. Purchase and shipping was a great experience also. I wish more businesses operated in this fashion. Scott

We run a lot of air tools at my race shop and couldn’t be happier with our compressor. It is quiet and builds pressure fast. Saw it at PRI and had to have it.

Viktor Kovalchuk –
I’ve spent hours browsing the internet for a quiet, powerful, good quality compressor and then I stumbled upon Eaton Compressor and after watching reviews of how quiet these are, I knew this was the compressor for me. The ordering process was very easy, the employees are very friendly and helpful which was also a big reason as to why I chose to buy from Eaton. When I received the compressor, I was very impressed by the build quality and I was even more impressed by how quiet it was. It’s definitely not whisper quiet but compared to other compressors i’ve owned, it’s incredibly quiet. I’d definitely recommend Eaton Compressors to anyone.

This compressor is great, it keeps up when I’m blowing out equipment which has never happened before. It’s fast, smooth and quiet. After my electrician wired it and turned it on he was so impressed with how smooth and quiet it is he took a picture of it to recommend it to other people. Very nice company to work with. Highly recommend!

Bob Flatt (verified owner) –
Very happy with this air compressor. It is American made that is a big plus. The ease of purchasing and shipping was great. The people where very friendly and knowledgeable. I had called several times with questions before I purchased and the staff always answered those questions. And the most important thing of all, is that I am very very pleased with this air compressor. My air tools make more noise then the air compressor does. Very quick recovery. Still surprises me on how quiet it is. Has a great warranty. Would purchase this again!

Super quiet and a huge step up from my old compressor. Provides all the air I need for my vaporhoning cabinet and other air tools. My only complaint is that it didn’t come with the recommended mounting pads.

This is one serious piece of equipment! I purchased it back in July and have been running it for a few months. It keeps up with my sandblast cabinet and my plasma table running at the same time. I love the fact I can carry a conversation without having to yell over the top of the noise. Five stars all the way.

I bought this to replace the 40 year old emglo in my body shop, wow what a difference!!! Pumps up in about 2 minutes and recovers very quickly and quiet as can be. Great people to deal with and fast shipping, and this is the only compressor that I found with a 5 year warranty! Most the others have a 1 year. Looking forward to putting some hours on this compressor, great job Eaton compressor!

I bought this compressor to replace an older Sanborn 80 gallon 2 stage compressor that was limping along for years. I had initially looked into getting an IR T30 compressor, but the specs on the Polar looked a bit better so went with Polar. The compressor was packaged very well on the shipping crate and appears to be very good quality. The operation of the compressor is probably the best feature…it’s really quiet! It’s definitely not “silent” but it is significantly quieter than the Sanborn I replaced. I did measure the sound level with the NIOSH sound level meter app from about 6ft away and the Polar runs at about 77dB while the Sanborn was 87dB. A 10dB reduction is a 10x reduction in the sound pressure level, so that reduction is impressive! Very happy customer.

I purchased the 7.5hp Industrial Plus Compressor with Silent Air and auto-drain, and I received it within a month of ordering. The sales office and techs are responsive and knowledgeable. Silent Air makes it nice to be around while it’s running vs my old compressor. I like to support products made in the U.S. and this is a great product made in the U.S.!

Jason K –
I have the Emax version of this unit and it is a beast! The company photos are a bit out dated, as Emax moved the silencer portion to the left side of the tank, making it easier to clean the filters. I contacted Emax customer service a couple times and was connected to a tech guy (in the US!) who answered all my questions.
While the unit isn’t silent, it’s quieter than a 30 gallon Craftsman that this is replacing and fills the tank significantly faster.
This will be used primarily for a blasting cabinet. It’s kept up so far with no issues. I also like how it came with an auto-drain assembly and already had the continuous mode hardware installed.
Well done, Emax!
