VHR 1405R
Heat Recovery Ventilator
Fantech's most popular HRV for house projects that require demand higher
efficiency, the VHR 1405R 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 1405R incorporates a unique and
quiet internal recirculation defrost that does not depressurize the home during
the defrost cycle.
During the defrost sequence, a motorized damper temporarily blocks the incoming
fresh air stream so that the warm air from the house can circulate through the
HRV. The exhaust blower shuts down and the supply blower switches into high
speed to maximize the effectiveness of the defrost strategy. During this cycle,
household odors from the kitchen or bathroom are prevented from entering the
home and the unit will not create negative pressure.
