About Master Flow™ Replacement Motors

  • High Efficiency:  PSC (permanent split capacitor) motor is more efficient and runs cooler than traditional shaded pole motor designs.
  • Convenient:  Existing power attic vent may be left in place during motor replacement without the hassles of removing the vent.
  • Specially Designed:  Genuine replacement motors for current and previous Master Flow® Power Attic Vent Roof and Gable mount models (See chart below).

See Master Flow™ Powered Ventilation Products Limited Warranty for complete coverage and restrictions.
Visit the Attic Ventilation Calculator for details.

Note: Always have a balanced ventilation system. In no case should the amount of exhaust ventilation exceed the amount of intake ventilation.
