Ewc Controls END-20X16 Nd Motorized Damper 20x16 in

Product Description

The EWC CONTROLS END-20X16 is a rectangular motorized zone damper designed for installation in HVAC ductwork as part of a zoning system. Operating at 24 volts, this damper controls airflow to individual zones, allowing the system to direct conditioned air only where it is needed. The unit features an onboard LED indicator that lets the installing technician visually confirm damper operation without additional test equipment. A reinforced frame speeds duct insertion and reduces fitting time on the job. Nylon bushings in the motor assembly reduce operational noise, cutting down on homeowner complaints and repeat service calls.

The END-20X16 is sized at 20 inches by 16 inches and is suited for rectangular duct applications in residential and light-commercial HVAC zoning systems. It is appropriate for air quality and zone control installations where airflow regulation across multiple zones is required. The side-mounted motor and three-wire connection make it compatible with standard low-voltage zone control wiring configurations. HVAC technicians installing Ultra-Zone or similar multi-zone systems will find this damper a direct fit for larger trunk and branch duct runs.

Compatibility

Designed as an OEM-style motorized zone damper for use in residential and light-commercial HVAC zoning applications requiring a 20-inch by 16-inch rectangular duct damper operating at 24 volts.

Installation Notes

Installation should be performed by a licensed HVAC technician. De-energize the zoning control panel and the air handler before beginning damper installation or wiring. Confirm duct dimensions match the 20-inch by 16-inch damper opening before securing the frame. Follow all applicable local mechanical codes and manufacturer wiring diagrams when connecting the three-wire low-voltage motor leads to the zone control board.
