65 | Dwell VHR 1404 Heat Recovery Ventilator Fantech's most popular HRV for home projects, the VHR 1404 is designed for higher static pressure applications. The unit brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. During winter, fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs, while during summer, the incoming air is pre-cooled if the house is equipped with an air cooling system. The VHR 1404 is equipped with automatic defrost mechanisms so you can use your HRV all year long. A preset defrost sequence is activated at an outdoor air temperature of 23ºF and lower. During the defrost sequence, the supply blower shuts down & the exhaust blower switches into high speed to maximize the effectiveness of the defrost strategy. The unit then returns to normal operation, and continues cycle.
