Regenerative Blowers

Republic Regenerative Blowers have decades of proven performance across hundreds of pressure and vacuum applications.

Republic Regenerative Blowers are available in single stage (one impeller), double stage (two impeller), or triple stage (three impeller) configurations:

Air Flow: From 50 cfm up to 776 cfm
Pressure Capacity: From 47" H2O to 337" H2O
Vacuum Capacity: From 40" H2O up to 281" H2O
Motor Grade: IP 44, 54, 55, B/F Class

The impeller is directly connected to the motor shaft and the bearings are outside the compression chamber, ensuring maximum operational reliability under high differential pressure.

How Does a Regenerative Blower Work?

A regenerative blower, also called a side channel blower or ring compressor, pulls air or gas into a side channel (1) through the air inlet (2). This air is progressively accelerated and pressurized by one or more impellers (3) rotating inside the impeller chamber (4). The resulting pressurized air or gas is discharged through the exhaust outlet (5).
