Signs of Positive Displacement Blower Failures

There are many common causes for blower failures. Rotary positive displacement blower equipment (Gardner Denver, Sutorbilt, DuroFlow, etc.) are fairly simple mechanical devices.  They consist of two rotors (2 or 3 lobes each) connected by timing gears, rotating inside a cylinder or housing.  Their spinning moves air from inlet to outlet, pumping against the system […]

Blowers are dumb beasts. They do not know nor care what is driving them.  They just rotate and move air. There are a number of methods of driving a rotary positive displacement blower. The simplest and preferred method is a simple flexible coupling, driving the blower at the same speed as the motor.  Woods Dura-Flex […]
