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 23F (-5C) 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 74%, standard MERV3 filters, a drain hose and hanging chain kit¹, 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.
