What does this mean? If your compressor does not have an after-cooler to cool the air as it comes out of the compressor before it goes into the tank, then the air may be too hot for most refrigerated air dryers to be effective in removing the water from the air. These dryers are designed to handle that high temperature air.

HOW TO DETERMINE THE CORRECT SIZE DRYER

An industrial grade piston air compressor produces about 3.5 CFM per horsepower. A rotary screw air compressor produces about 4.0 CFM per horsepower. So, if you have a five (5) hp piston air compressor it produces about 17.5 CFM, you should purchase a dryer that is just above that CFM rating.

AIR DRYERS DO NOT QUALIFY FOR THE FREE FREIGHT PROGRAM - THEY ARE SHIPPED FREIGHT LINE.
