The ICP CRTWOPOS011A00Two-Position Outdoor Air Damper is designed to provide a simple, reliable solution for introducing fresh outdoor air into compatible commercial packaged HVAC rooftop units. Operating on a two-position basis (fully open or fully closed), this motorized factory-engineered accessory opens to admit up to 100% outside air when the system runs and closes securely when the unit shuts off to prevent unwanted air infiltration.

Constructed from durable galvanized steel for long-lasting performance, this damper kit can be installed in either a vertical or horizontal airflow configuration. The damper assembly features adjustable travel limits, allowing HVAC technicians to easily preset the maximum outdoor airflow intake anywhere between 25% and 100% to meet specific ventilation codes and building airflow requirements.
