4RC620-H57 Regenerative Blower

The Republic 4RC620-H57 is a three phase, high pressure regenerative blower with a maximum air flow of 115 cfm, maximum vacuum of 209 in.H2O, and maximum pressure of 337 in.H2O.

Republic Regenerative Blowers are available in single stage (one impeller), double stage (two impeller), or triple stage (three impeller) configurations. The impeller is directly connected to the motor shaft, providing powerful force without undue friction. The bearings are outside the compression chamber, ensuring maximum operational reliability under high differential pressure.

A regenerative blower, also called a side channel blower or ring compressor, pulls air or gas into a side channel through the air inlet. This air is progressively accelerated and pressurized by one or more impellers rotating inside the impeller chamber. The resulting pressurized air or gas is discharged through the exhaust outlet.
