Fantech SH 704 - 56 CFM, Continuous Exhaust Defrost, Heat Recovery Ventilator 1400 Sq. Ft.
DetailsThe Fantech SH 704 Heat Recovery Ventilator, with its unique automatic defrost mechanism, lets your whole home have good ventilation throughout the year. This compact HRV has a side duct connection and ventilates your home by supplying fresh air and exhausting the same amount of contaminated air. During winter, the supply air is tempered by the heat transferred from exhaust air. This system lets you save huge amounts of energy. During summer, the incoming hot air is pre-cooled, if your home is equipped with an air cooling system. The automatic defrost system follows a cycle when the supply air stream temperature falls below 23F. The supply of incoming air is stopped, while the exhausting of air continues. After 3 or 5 minutes, the supply motor restarts automatically at the preset speed. This cycle ensures better defrosting during the winter seasons. It provides 56 CFM airflow capacity and can effectively serve 1-2 bedrooms. The HRV comes with an easy-mount wall bracket for easy installation.
