Atlantic Blowers AB-20004 2.5 in. Relief Valve

The purpose of a relief valve is to release the pressure buildup, also known as backpressure, in a blower system. Backpressure will cause the blower motor to overheat resulting in a burnt out motor and bearing failure. Backpressure is the number one cause of motor failure in regenerative blowers. A simple installation of a relief valve with proper calibration can prevent unwanted and unnecessary blower replacements, saving you time and money.
