Replacement Gast Regenerative Blower ONLY No filter or bleed valve Ideal for replacement applications where filter and bleed valve already exist. 6' power cord included on 1 hp and smaller units.
With a rugged construction that’s suitable for demanding applications, these blowers offer oil-less operation ensuring that the discharge air remains free of contamination. They can be mounted in any plane, which provides flexibility when mounting or integrating the blower into an OEM system. In addition, these blowers have very few moving parts and no wearing components, which minimize downtime and helps to lessen operating noise levels.
Thermal over load protection protects motor windings from damage should the blower become stalled during operation. Additionally, thermal over load protection switches automatically reset when single-phase motor windings cool to a safe level of operation.
UL and CSA certified TEFC motors with permanently sealed ball bearings offer increased protection against weather, dirt, and moisture. Permanently sealed ball bearings incorporate polyurea grease, which extends bearing life and offers superior resistance to washout, rust, and corrosion
Aluminum blower housing, impeller, and cover makes major components inherently corrosion resistant promoting extended product life.
