Ewc Controls END-8X16 Nd Motorized Damper 8x16 in 24V

Product Description

The EWC CONTROLS END-8X16 is a rectangular motorized damper designed for use in forced-air HVAC zoning and air quality applications. Sized at 8 inches x 16 inches, this normally-closed (ND) damper operates on a 24-volt control signal and features a bottom-mounted motor with a 3-wire connection. An integrated LED indicator light allows technicians to quickly confirm damper position during commissioning and service. The unit is suited for residential and light commercial duct systems where zone control or air quality management requires automated airflow regulation.

This damper is installed within rectangular ductwork to control airflow in zoned HVAC systems or dedicated air quality setups. The 24-volt motor integrates directly with standard zone control panels, thermostats, and air quality controllers commonly found in residential and light commercial installations. The bottom motor-mount orientation suits typical horizontal duct runs and panel-accessible installations. Licensed HVAC technicians handling zone system builds or retrofits are the primary installers.

Key Features

• Normally-closed (ND) design returns to closed position on power loss for safe default airflow shutoff
• 24-volt motor compatible with standard zone control panels and low-voltage thermostats
• 3-wire motor connection supports open, close, and common control wiring
• Bottom motor-mount configuration suits horizontal duct installations
• Integrated LED indicator light confirms damper status during setup and service
• Rectangular 8 x 16 inch profile fits standard rectangular duct sizing

Compatibility

Designed as an OEM-style motorized damper replacement or new-install component for rectangular duct zoning and air quality systems operating on 24-volt control circuits.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems and applicable mechanical codes. Shut down the air handler and de-energize the control transformer before wiring the damper motor. Confirm duct dimensions match the 8 x 16 inch damper frame before securing in place. Verify LED indicator function and damper travel after wiring to ensure proper operation before closing the system.
