VHR 2004
Heat Recovery Ventilator
Fantech’s largest residential, full-featured HRV for budget conscious large house
projects, the VHR2004 is designed for higher static pressure and higher airflow
applications. 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 2004 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.
Airflow up to 201 cfm @ 0.4” Ps serves 7 bedroom homes
Three speed ventilation control
External dry contacts for quick connection of remote controls
Compatible with Fantech's low-voltage controls
