Ewc Controls END-8X20 Nd Motorized Damper 8x20 in 24V

Product Description

The EWC CONTROLS END-8X20 is a rectangular motorized damper measuring 8 inches by 20 inches, designed for zone control and air quality applications in ducted HVAC systems. Operating on 24 volts, the damper uses a bottom-mounted motor with a 3-wire connection to provide reliable open and close control of airflow within a duct system. An integrated LED indicator light allows technicians to confirm motor position at a glance during installation and service. This unit is installed by licensed HVAC technicians as part of zoning or air quality control systems.

The END-8X20 is suited for residential and light commercial HVAC zoning systems where precise airflow management is required. Its rectangular profile fits standard 8-inch by 20-inch duct openings, making it a direct fit for common supply or return trunk configurations. The 24-volt control voltage is compatible with standard zone control panels and low-voltage thermostatic controls used in typical forced-air systems. Technicians working on air quality or multi-zone HVAC installations will find this damper a straightforward addition to existing ductwork.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect power to the air handler and zone control panel before installing or servicing the damper. The 3-wire low-voltage connection must be wired to a compatible zone control board following the control board manufacturer's wiring diagram. Verify duct dimensions and motor clearance before securing the damper in place.
