Gast’s Regenair regenerative blower line for high volume vacuum or compressed air applications offers both motor-mounted and separate drive models. Also we offer regenerative blowers with explosion-proof motors for Soil Vapor Extraction.
 
  • Double-sealed, permanently lubricated bearings on many models minimize maintenance whiles 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
