The ULTRA-AIRE ultra-4023672 is a 6-inch motorized damper designed for use with ULTRA-AIRE 100V series dehumidifiers. The damper controls airflow through ductwork by opening and closing on demand from the dehumidifier control signal. It serves as a critical component in whole-home ventilation and dehumidification systems, helping regulate fresh air intake and preventing conditioned air from escaping when the unit is not actively running. Licensed HVAC technicians and mechanical contractors typically install this accessory as part of a ducted dehumidification system.
This motorized damper is used in residential ducted dehumidification setups where the ULTRA-AIRE 100V series unit is integrated into the home ventilation system. It is mounted inline in the ductwork to manage airflow coordination with the dehumidifier, ensuring the system operates efficiently by only allowing air movement when commanded. Typical installations involve attic, basement, or crawl space dehumidification systems where controlled ventilation is essential to moisture management.
Designed for use with ULTRA-AIRE 100V series dehumidifiers as a ventilation control accessory.
Installation should be performed by a licensed HVAC technician familiar with ducted dehumidification systems. Disconnect power to the dehumidifier and any associated air handling equipment before beginning installation. The damper must be mounted in the correct airflow direction as indicated on the unit body, and all duct connections should be sealed to prevent air leakage. Follow local mechanical codes and manufacturer documentation for wiring the motorized actuator to the dehumidifier control circuit.
