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 18 CFM Displacement and a Free Air (usable air) of 14 CFM @ 90 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 18 CFM Displacement.  I have seen companies advertise this as "18 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 18 to 14 @ 90 PSI.  We give you the "Free Air" @ Pressure and the CFM Displacement--NOTRICKS!!!  This pump has a maximum PSI of 135.  There are companies also advertising this as up to a 7 HP--this is also untrue, they are giving you the "Peak" Horsepower when it really takes half the horsepower they advertise to pull it at maximum RPM.  By doing this, you have been tricked and think you are getting a 7 HP, but you are really getting a  HP pump--THE TRUTH!  Our name for our HP is the "TRUTH HP".   To gauge your motor HP, check the amperage on 220V.  It takes 19.5 amps (running amps) to pull this pump.  This pump can be slowed down by putting a smaller pulley on your motor and it can be ran with a 3 HP motor pulling 15 amps on 220V (running amps) Please note:  DO NOT go by the HP being advertised on most compressors because your motor will not be big enough to pull your pump.  The”. Minimum RPM is 600 and a maximum RPM of 1080.
