ATMO 15H fresh air appliance continuously supplies 150 cfm of fresh, filtered air while removing an equal amount of stale air. Controlled ventilation ensures home occupants receive the highest level of comfort. Up to 75% of the heat in the extract air is recovered by the heat exchanger and used to temper the fresh air coming from outside. ATMO 150H is designed for high static pressure applications that demand high efficiency. The product is equipped with an automatic defrost mechanism that is activated when outdoor air temperature drops to 23 deg F (-5 deg C) or lower. During the defrost cycle, the supply air fan shuts down while the exhaust air fan switches into high speed to maximize the effectiveness. The appliance features an efficient crossflow heat exchanger with SRE up to 75%, standard MERV 3 filters, a drain hose and hanging chain kit, easy connect ports, integrated air balancing taps and duct ports with plastic collar shrouds for simple and quick installation. Comes with a limited warranty (lifetime warranty on the exchanger, 7 years on motors and 5 years on parts). ATMO 150H has been tested in accordance with Home Ventilating Institute (HVI) certification program to ensure it meets HVI ratings for airflow and energy.
