The element is installed within a 10-inch round duct provide the TRC500 energy recovery ventilator to regulate airflow through the ventilation of HVAC system. By reducing air backflow, limiting the entry of outside contaminants, and supporting controlled ventilation, it maintains stable airflow conditions and overall system efficiency.
