Regenerative Blowers

Gast's Regenair regenerative blower line for high volume vacuum or compressed air applications offers motor-mounted, separate drive, and models with explosion-proof motors used in Soil Vapor Extraction (SVE).

· Double-sealed, permanently lubricated bearings on many models minimize maintenance while maximizing performance
· The design ensures exhausted air is always clean and oil-free
· Integrated mufflers on single ended units minimize operating noise and eliminate the hazard of an exposed impeller
· Strong fan cooling helps dissipate heat around bearings and impeller housing, prolonging bearing life and allowing cooler air delivery.
· All blower models shown are equipped with UL & CSA certified motors except separate drive models
