The Difference:

                Eaton Compressor delivers overwhelming performance to ensure that they meet the needs of the most demanding environments. Our Pumps require less maintenance, service and downtime than any other compressors in the Air Industry’s. All our Products are designed with exacting tolerance and specifications to deliver all the power that is needed at the jobsite, garage or shop.

“Free Air”:

                Our 3 Cylinder Heavy Industrial air compressor pump with 32 CFM Displacement and a Free Air (usable air) of 26 CFM @ 100 PSI can’t be beat. Don't be tricked by air compressor dealers giving you CFM Displacement and you think you are getting the Free Air...and you are really not.  For instance, this pump has 32 CFM Displacement.  I have seen companies advertise this as "32 CFM @ 125 PSI"--this is not true!  Displacement is the bore of the cylinder times the distance in the piston stroke times the RPM at zero pressure, but as you go up in pressure, you will lose efficiency on your pump.  The CFM will diminish from 32 to 26 @ 90 PSI.  We give you the "Free Air" @ Pressure and the CFM Displacement--NOTRICKS!!!  This pump has a maximum PSI of 150. The minimum RPM is 600 and a maximum RPM of 840. 

This pump is all cast iron.  When we say ALL CAST IRON, (not aluminum) that is what we mean.  It has solid cast iron cylinder, cylinder heads, crankcase, flywheel, crank, and forged steel connecting rods – not aluminum!  99% of the pumps you see on the market today have aluminum rods.  This style rod does not come close to a forged steel rod.  I have seen many compressors over the 26 years of building compressors, and many of them break – aluminum rods.  However, I have NEVER seen a steel connecting rod fail in one of our pumps.  The forged steel connecting rods are a $120.00 option included on our pump.  These rods also have a replaceable bearing on the crank journal and on the wrist pin journal.  This is what most of the competition do not have.

We are loving the compressor. It is so quiet compared to our old one & very efficient. Thank you for making such an high quality product. We hope it will last for many years to come.

I have had my 3 cylinder 7.5 horse pump for a little more than a week now. I LOVE IT! It is everything they have advertised! Slow RPM, quiet, puts out plenty of air. Heavy! These things are built solid. Megan Cain was very friendly and hepful on the phone when I ordered. She really knows her pumps. She took the time to answer any questions I had, and matched their pump to my old unit perfectly.
I had previously stopped at the Polar showroom in Clayton, OH when on a trip with my family. Matt Cain showed us compressors and talked to us like old friends. This company is a class act. Their product speaks for itself. If anyone needs a compressor I know where to send them, no questions asked. Hands down BUY POLAR!!!

I bought one of your compressors pumps a little over a year ago and just wanted to let you know how pleased I am with it. I am a farmer and use my compressor daily. When I first installed the compressor pump, I would often check to see if it was working or not because it was so quite (You can talk on a phone next to it and hear what is being said). It is a good value for the dollar and has never failed to keep me well supplied with all the air I need.

It is not often I remark upon a product I buy, but this pump has exceeded my expectations by a wide margin. I would, and have, recommended you company to anyone who needed a compressor.

This is the best one yet! Eaton Compressor, Super quiet compressor. Awesome!

Matt Cain President/ CEO 27/08/2015

Eaton Compressor Since 1977....Our air pumps are a great replacement for any failed compressor that needs a new pump. Our quality is only the best, each pump carries a 5 year warranty on all parts and is not a pro rated warranty. Our Pumps are the best choice, because of the high quality we manufacture and are a proven design. Our motto is... Go big or Go home! That is why our BIG Eaton pump is one of the lowest RPM Compressors built on the market today. Low RPM is quieter, generates less heat and increases pump life. We offer all cast iron construction (not aluminum). Real Cast Iron connecting rods, Real Cast Iron cylinder heads, Real Cast iron crankshaft, Real Cast Iron Flywheel, Real Cast Iron inner and after coolers. The Eaton pumps are precision CNC machined and are balanced for smooth operation. If you are looking to save money and get the best quality Eaton Factory direct pumps are your best choice. We carry a full line of parts, and have the best service!
