Gast R3105-12 Regenerative Blower 1/3 Hp 50 inH2O 52CFM


With a rugged construction that’s suitable for demanding applications, the R3 Series offers oil-less operation, ensuring that the discharge air remains free of contamination. The R3 Series 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 minimizes downtime and helps to lessen operating noise levels.

Other features include:

  • Thermal overload protection to safeguard the motor windings from damage should the blower become stalled during operation;
  • Thermal overload 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; and
  • Aluminum blower housing, impeller, and cover help keep the R1’s major components resistant to corrosion promoting extended product life.
