Also known as regenerative blowers, use these to produce high-flow compressed air with low pressure or vacuum to operate pump drives, lift tables, and conveying systems. Compressed air blowers are also used for drying, exhausting, and aeration.

Air circulates inside the blower housing to compress air, which generates pressure or vacuum. Single-stage blowers circulate air once and then exhaust.

Inverter-rated blowers have a motor that can run at slow speeds without overheating, so they can be used with a motor speed control (variable frequency drive).
