Ewc Controls END-16X8 Nd Motorized Damper 16x8 in 24V

Product Description

The EWC CONTROLS END-16X8 is a rectangular motorized zone damper in the ND Ultra-Zone series, designed for use in forced-air HVAC duct systems. Sized at 16 inches by 8 inches and operating on 24 volts, this damper controls airflow in zoned residential HVAC applications. It features a side-mounted motor and nylon bushings for quieter operation, along with an LED indicator light that allows technicians to visually confirm damper position and operation during checkout. The 3-wire motor connection integrates with standard zone control wiring. The reinforced frame is built for faster duct installation and long-term durability.

This damper is used in residential zoning systems where individual rooms or areas require independent temperature control. It sits in the supply duct and is actuated by a zone control board responding to thermostat calls. The ND series is intended to reduce noise complaints and callback rates in occupied homes, making it well-suited for retrofit zoning projects as well as new construction duct systems. HVAC technicians install this unit as part of a complete zone control layout managed by a compatible EWC or similar 24-volt zone panel.

Key Features

• LED indicator light for visual confirmation of damper position during installation and checkout
• Nylon bushings reduce operating noise for quieter performance in occupied spaces
• Side-mounted motor for straightforward duct integration
• 3-wire motor connection compatible with standard 24-volt zone control wiring
• Reinforced frame for faster, more secure duct installation
• Rectangular shape sized at 16 inches by 8 inches for common duct openings

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for residential forced-air zoning systems using 24-volt zone control panels.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Shut down the air handler and de-energize the zone control panel before installing or wiring the damper. Verify that the duct opening matches the damper dimensions before securing the frame, and confirm motor rotation and LED status at the zone panel during system checkout. Follow applicable mechanical codes and the zone control manufacturer wiring diagram for low-voltage connections.
