Fantech SHR 6904 - 690 CFM, 3 Speed, Fan Shut Down Defrost, Heat Recovery Ventilator
Install the Fantech SHR 6904 Heat Recovery Ventilator to provide proper ventilation to your house.
The Fantech SHR 6904 Heat Recovery Ventilator is designed to supply fresh outdoor air into a building while exhausting the stale indoor air to the outside. The aluminum heat exchanger core transfers heat from the exhaust air stream to the incoming air stream resulting in tempering of the fresh air and less load on the HVAC system. The ventilator allows airflow up to 687 CFM at 0.4" PS. When the outdoor air temperature is 23 F and less, a preset defrost sequence is activated. During this sequence, the supply blower shuts down and the exhaust blower switches to max speed to provide an efficient defrost strategy. After completion of the defrost sequence, the unit goes back to the normal mode. It has a push pull configuration for effective performance. External low voltage contacts, a reversible electrical box and an external 3-position switch are provided for easy operation.
