The Difference:

                Airbase Industries by Emax Compressor  delivers overwhelming performance to ensure that they meet the needs of the most demanding environments. 25 HP compressor 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”:

            This is our 25 HP, 4 Cylinder, 2-Stage, air compressor pump with 98 CFM Displacement, 89 CFM @ 175 PSI, and 93 CFM @ 100 PSI. This unit has an SCFM @ 175 of  89. This is usable air or “free air” at pressure – 175 PSI. 25 hp air compressors pump can go to 200 PSI, but what we tell all of our customers is even though the compressor will go to a higher pressure, you should run it at the lowest pressure possible to maintain the air pressure needed. This will give you a higher CFM at a lower pressure and the compressor will run cooler with less compressor wear. This is true with any compressor on the market. Lower pressure combined with lower RPM will give you great results and a compressor that will last for many years. We have this style compressor, 4 Cylinder, in factories, body shops, and many tough applications that we sold over 20 years ago.  This pump runs COUNTER CLOCKWISE rotation as you are looking at the compressor fan or flywheel. This pump runs at a SUPER slow RPM of 800. It can be slowed down to 600 RPMs and run with a TRUE 20 HP motor.  Minimum RPM on this pump is 550..

                This pump is ALL CAST IRON, (not aluminum).  It has solid cast iron cylinder, cylinder heads, crankcase, flywheel, crank, and forged steel connecting rods – not aluminum!   These rods also have a replaceable bearing on the crank journal and on the wrist pin journal. 

Our 25 hp air compressor pump has large Timken-Style roller bearing on the crank ends on each end of the crankshaft.  This ensures good crank stability and long compressor bearing life.  Each cylinder is all cast iron with no sleeves or aluminum.  All cast iron prevents cylinder distortion and egg-shaped cylinders when pump gets hot.  This pump has 2 B-Section belt drive.  Twin belt ensures better belt gripage and longer belt life.  This pump has head unloaders.  This is very nice for continuous run applications such as gasoline driven or electric driven high duty cycle applications.  Head unloaders are an air cylinder in each head.  When air is applied to them, they open or push the intake valves open allowing the pump to go into a free wheel mode.  The cylinders are still moving in a free wheel mode, but it cannot compress the air because the intake valve is held open.  This pulls cool air into the cylinder.  The cool air absorbs the heat in the pump and blows it back out the intake valve.  This is nice when you are sandblasting, etc., under heavy duty cycles.  This pump has a site glass to view your oil level.

We have had a great experience with these compressors. They have proven them self to be exactly what Matt Cain said they would be. We are secure and confident with the 10HP and the 25HP compressors.

Works only half as hard as my old ingersal rand and quit enough to talk inside the equipment room rather than having to go outside
