EMAX APP2V0732S : 5 HP 32 CFM Single Stage Reciprocating Air Compressor

The Emax 2 Cylinder Heavy Industrial air compressor pump with 32 CFM Displacement and a Free Air (usable air) of 19 CFM @ 100 PSI can’t be beat. 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.   This pump has a maximum PSI of 150. The minimum RPM is 600 and a maximum RPM of 840. 

This pump can be run with a gasoline engine.  It is set up with head unloaders.  This will allow the pump to unload the valves in a continuous run application.  This is on top of the heads with the small 1/4″ lines connecting them.  This also allows for complete unloaded, no-load start, easy on your gasoline engine starter.  You must have an 8-10 HP to run this at a minimum RPM and a 13 HP to run it at maximum RPM.  It takes 21 amps (running amps) to pull this pump at a 640 RPM speed.  The motor used to do this should be a 1750 RPM, 184-T Frame.  It will give you a much higher starting torque than a 3450 RPM motor.  For an 840 RPM speed, you should use a TRUE 7.5 HP, 32-amp, 215-T Frame, 1750 RPM motor.  A 3450 RPM in this HP is also not recommended because of lower starting torque.  This pump can be slowed down by putting a smaller pulley on your motor and it can be run with a 5 HP motor pulling 21 amps on 220V (running amps).
