Silent Air™
Patented Noise Suppression System – Up to 50% Quieter
Silent Air Technology
This intelligent design achieves up to 50% quieter operation—with noise levels at or below conversational volume (each 10 dBA drop equals a 50% reduction to the human ear). Unlike enclosed cabinet systems, which are costly and restrict service access, our silencer is costeffective, easy to service, and doesn’t compromise accessibility.
Noise Reduction
Our Silent Air™ patented silencer system sets us apart as one of the quietest compressor brands on the market.
Air Filtration
Designed to reduce intake noise—the loudest source of compressor sound—this system
uses:
● Noise-reducing baffle plates
● High-capacity filter media
● Up to 1000% more filtration than standard setups
Pressure Lubrication Pump
Maximum Protection for Critical Components
Pressure lubrication reduces friction and internal wear by delivering a continuous flow of oil to
each bearing point via a gear oil pump, keeping bearings cool and extending pump life. Each
crankshaft and connecting rod is gun-drilled for precise oil flow, while a spin-on
automotive-style oil filter ensures clean oil for maximum longevity. An analog pressure gauge
allows operators to monitor oil pressure accurately, providing reliable performance and peace of
mind.
100% Cast Iron Pump Features
Many compressors rely on aluminum components, which do not offer the same durability and
rigidity as cast iron. All major components of our compressors are constructed from cast iron,
including:
● Crankcase
● Cylinder heads
● Cylinders
● Connecting rods
● Crankshaft
● High-pressure piston
High Performance
Pressure Lubricated pumps feature a high-performance pressure lubrication system, delivering superior
protection and longevity under demanding conditions. A gear-driven oil pump, mounted to the rear of
the crankshaft, generates positive oil pressure, ensuring consistent lubrication throughout the
system.
Rifle Drilled
All crankshaft and connecting rods are rifle-drilled, allowing direct oil flow to key wear points—
including bearings and other high-friction components. A SPIN ON automotive-style oil filter
provides clean, efficient filtration for optimal performance and simplified maintenance during oil
changes.
Critical Components Coverage
Unlike splash-lubricated systems, pressure lubrication delivers oil precisely where it's needed, reducing friction, wear, and heat—especially in high-stress, continuous-duty environments. This is the most effective method for keeping your compressor running stronger, longer.
Optional Head Unloaders
Head unloaders are ideal for constant-run applications. They relieve the intake valve during
operation, improving pump cooling and reducing overall wear under heavy workloads. This
feature enhances reliability and extends the service life of the compressor in demanding
environments. On our gas-powered compressors, continuous-run head unloaders provide
decompression during engine startup, reducing load on the electric starter and ensuring smoother,
more efficient starts.
Piston Rings
Our pumps utilize a four-ring piston design, featuring precision-engineered overlap rings that
minimize compression loss and significantly reduce oil carryover. This configuration enhances
sealing efficiency, improves overall pump performance, and supports long-term reliability under
demanding operating conditions.
Gaskets
Our pumps feature high-quality, non–oil-absorbent gaskets designed to minimize oil leakage.
This ensures a more reliable seal, reduces maintenance requirements, and contributes to the
long-term efficiency and durability of the pump.
Disc Valves
Our disc valve system is engineered to deliver exceptional durability in both intake and exhaust
functions, ensuring reliable performance over decades of use. This design enables efficient
maintenance without the need to remove the cylinder head, significantly reducing service-related
downtime. In contrast, many competitors rely on reed valves, which require head removal and
are less suitable for demanding, heavy-duty applications.
Flywheel
Each compressor pump is fitted with a large cast iron flywheel to increase kinetic energy and
reduce motor strain. We offer both dual-belt and triple-belt configurations. All pumps utilize
standard B-groove belts, which provide increased belt-to-flywheel surface contact, enhancing
belt longevity. The flywheel has large cooling fans which increases airflow across the pump.
Cylinder Heads
Unlike traditional aluminum heads—known for their susceptibility to gasket failure—our cast
iron cylinder heads and valves are precisely machined to deliver superior strength, reliability, and
long-term performance.
Bearings
Our pumps utilize tapered roller bearings on both the front and rear of the crankshaft to ensure
smooth, reliable operation. The automotive-style connecting rods feature rebuildable bearings at
both the piston pin and the crankshaft connection. In contrast, many competitors rely on
aluminum connecting rods, which are non-rebuildable and must be discarded when worn.
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.
- 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
Continuous Run/Dual Control Feature
Smart Energy-Saving Operation
Dual Control
Our dual control system offers greater operational flexibility. Choose between Auto Start/Stop Mode
or Continuous Run Mode based on your compressor’s usage pattern:
● Auto Start/Stop is ideal when usage is 30% or less.
● Continuous Run is better when frequent cycling exceeds 30%.
Continuous Run Mode
The Continuous Run Mode decompresses the intake valves using a pilot valve with a preset PSI, reducing start-up stress on the motor. This prevents wear on the electric motor, centrifugal switch, magnetic starter, and cuts down on energy spikes—helping to lower your electricity bill. Additionally, when freewheeling (not compressing), the pump continues to cool internally, helping dissipate excess heat generated during compression and protecting the system from long-term wear.
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.
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.
Belt Tensioner
Smooth, Accurate, and Long-Lasting
Dual-Bolt Belt Tensioner
Our dual-bolt belt tensioner makes belt adjustments easier and more precise. This design ensures proper alignment while maintaining optimal belt tension, reducing wear and tear for longer belt life and enhanced serviceability. Using pry bars to tension your belts is no longer required.
Belt Drive | V-Belt Design
Power You Can Rely On
Unlike competitors using narrow, single A-width belts, our compressors feature a multi-belt drive
system with B and C-width belts. This design provides:
● More surface area for better grip
● Reduced belt tension, minimizing strain on motor and compressor bearings
● Lower noise and vibration, extending belt and system life
The result is a durable, efficient, and a low-maintenance drive system built for thousands of hours
of trouble-free use.

The sales team was friendly and helped me find the right compressor for my shop. This compressor is high quality, built well and truly is quiet especially when compared to other manufacturers. I love that I can carry on a conversation with someone near the compressor without having to yell to hear each other. It is also very efficient and builds pressure a lot quicker than any compressor I have used before so it’s not running long periods of time to build back up. I have no complaints about this compressor and I will definitely use more of their products in the future.

This is a great USA made air compressor. It is well built and runs so smooth. I was worried about it being damaged during shipping, but it was packaged well and was delivered in great shape. This compressor is quieter and puts out 3 times the air of my last one. I can finally use my sand blaster and have plenty of air! Matt, Megan, and the whole team are very knowledgeable and are great to work with.

Outstanding service and equipment! My third purchase over the past 5 years to include 2 piston compressors and a 58 cfm refrigerated air dryer. Recently purchased my second Polar Air 80 gallon 2-Stage Piston Air Compressor which features 10hp, single phase, silent technology, and auto drain which without question runs quieter than other units I’ve used and keeps up with my media blasting and powder coating with no issues. I Highly recommend their products which are offered at a GREAT Value! Thank you again Matt and Eaton!!

Really happy with my purchase. I don’t think a time will ever come when this compressor won’t be enough. It’s an extremely capable machine that produces an insane amount of air very quickly. I will say that it is extremely quiet compared to standard compressors and you can talk next to it without really yelling, but any level of “I can have a phone call next to it” seems like a stretch. It’s not silent by any means but the biggest impact is the lower RPM. This cuts down on high frequencies which is really where the benefit is.
I had trouble with the final destination shippers and my box was a bit beat up when it arrived. As a result (I believe), the pressure switch wasn’t functioning properly. It did take a moment to get someone to help diagnose it (they seemed pretty busy) but once that was done, they shipped a new switch out immediately and got me up and running. I’d say that I would purchase again but my grandkids will be fighting over it in 50 years so no day will come when I need to.

In 2018 I searched for a good compressor for myself and found and purchased a 5HP Polar Air Compressor. I am very particular about buying quality personally. I am part of the team at Larry Romance and Son and when they need something, I am in a position where they knowing how particular I am about quality, will ask for my input. Thus, this opportunity of needing a good-sized compressor came up for our tire division. It is awesome!!! It is so quiet. We are very happy with it. Quality shows in every aspect of it !!! About a year ago we had an immediate need for our main shop and they bought locally. I knew we wouldn’t be able to buy one from you considering the lead time. It is LOUD and sounds like a giant sewing machine !!! Great Job Eaton !!!

In 2024 I decided to look for a well made powerful air compressor. I came across the polar air 10hp 2 stage 80 gallon air compressor. I did my homework on the air compressor and was very impressed with how quiet and powerful it is. I purchased the air compressor for my small engine repair business and boy am I glad I did. This air compressor is quiet, plenty of cfm for my needs and is a rock solid compressor. If you are in the market for an air compressor, look no further. Eaton has you covered.

I recently purchased the 10 hp single phase Industrial Plus unit from the good folks in Clayton, Ohio and first and foremost, I must complement their sales and support staff. Everyone I spoke with was/is knowledgeable, competent, polite, and well-prepared to meet the needs of their clientele. The support behind the unit speaks to the quality and dependability of the unit before it is ever un-crated. Further, I was able to install a (likely) larger unit than may have been required at this time, but Eaton’s pricing structure and the quality of the build make it easier to afford the additional capacity now at a lower price point. Every part of the unit features first quality parts and first quality workmanship. The fit and finish indicate the unit is as well-built as it is well-designed. The unit is quiet, starts easy, runs at low speed, and never starves the distribution system for air. I have been involved with the design, installation, and use of these systems for well over forty years, and can recommend this equipment and this supplier with the highest degree of confidence.

after doing some research I contacted Eaton compressor for more information about their 10 hp quiet air compressor. I was impressed with the knowledgable courteous staff and selected the Polar air 10hp industrial plus unit for my home shop. the unit came packaged well and is a well built unit. After installation I fired it up and was impressed with how quiet and smooth it runs from my old 7.5 hp devilbuss compressor. I highly recommend this unit and look forward to years of quiet use.

This compressor os a hige upgrade from my previous husky. It can easily keep up woti a sand blaster and multiple air tooks tust run continuously. For the price though, i do wish that the electric box was better secured as it vibrates quite a lot and reauired me to add a third bolt to mount it more secirely. Additionally it would be nice if it came with the hour meeter already installed instead of requiring a seperate purchase and customer install, Especially since oil change intervals are based on hours.
The unit also came low on oil Requiring me to purchase my own. ThenThen after about two hours of runtime, the oil pressure dropped below the minimum so I had to adjust this up to keep it at the rated 20 psi. ThThe belts also started flaking small bits of rubber off of them, though they do look to be at the correct tightness and in alignment. I reached out to customer service and was able to get a new pump under warranty which I’m hoping will fix these issues. For all of the problems I’ve had, they have stood behind their product with good customer service, which is appreciated.

Nice COMPRESSOR but comes with some drawbacks. OVERALL, this COMPRESSOR is a beast and boasts a duty cycle I’ll likely not ever exceed but there were some DISAPPOINTMENTS upon RECEIPT. First, the compressor arrived about 1/2 quart low on oil. Since this requires oil not readily AVAILABLE off the shelf, i had to purchase this out of pocket before I even ran the unit. Secondly, MAINTENANCE is calculated by hours, but an hour meeter is an extra charge, and requires the customer to install. For the 5k price tag, it would be nice to have this as standard EQUIPMENT. Third, the oil pressre dropped so low after the first two hours of use that i had to manually adjust it twice, resulting in a 60psi cold start, and a 15 PSI pressure when at operating temp. Upon bringing this to customer service, a new pump was sent and will be installed under warranty so that is technically resolved. Lastyl, the pressure switch was set too low so that continuous run feature didn’t RELIABLY operate. This took a while to get to the bottom of but I Finally found the cutin/cutout pressure had been set at 100PSI/140PSI.
Overall, all of these issues could have been take care of it the unit was test run before shipment and its DISAPPOINTING that none of these were addressed before I received the unit. Its OBVIOUS to me that some QA improvements are needed before certifying for shipment.
