Description
The Lennox 74N94 Damper Motor Bi-Direct Gold is a replacement part for Heat Reco Ventilators (HRVs). An HRV recirculates fresh outdoor air into the building while replacing the old indoor air without much loss of heat or coolness. The damper motor is one of the smaller parts of the HRV, yet it is incredibly crucial. It both admits and shuts dampers for the management of direction of the air flow within the system. This bi-directional motor is used to control exhaust and intake operations as well. This uses normal 110V AC household current and draws only 5 watts of power.
