Ewc Controls END-18X10 Motorized Damper 18x10 in

Product Description

The EWC CONTROLS END-18X10 is an 18-inch by 10-inch rectangular motorized zone damper designed for residential and light commercial HVAC zoning systems. Operating on a 24-volt control signal, this ND-series damper regulates airflow through ductwork to maintain comfort in individual zones. A side-mounted motor drives the blade assembly, and nylon bushings reduce mechanical noise during operation. An integrated LED display lets technicians visually confirm blade position and damper status during startup and checkout, reducing diagnostic time on the job.

The END-18X10 is suited for rectangular duct installations where zone control, air quality management, or variable airflow is required. The reinforced frame is sized at 18 inches by 10 inches and is designed to drop into duct openings quickly without requiring special tooling. Three-wire motor wiring simplifies integration with standard zone control boards and thermostats. Licensed HVAC technicians and sheet metal contractors are the typical installers for this type of damper in forced-air zoning applications.

Key Features

• 24-volt operation compatible with standard zone control systems
• Integrated LED display for visual confirmation of damper position during checkout
• Nylon bushings reduce operating noise for quieter zone transitions
• Side-mounted motor with 3-wire connection simplifies wiring to zone boards
• Reinforced rectangular frame for faster, more secure duct installation
• Rectangular shape fits standard 18-inch by 10-inch duct openings

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular duct zoning systems operating on 24-volt control circuits.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. Power down the air handler and de-energize the zone control board before connecting or disconnecting the damper motor leads. Verify duct dimensions match the 18-inch by 10-inch frame before cutting or modifying existing ductwork. Follow local mechanical codes and manufacturer wiring diagrams when connecting the 3-wire harness to the zone controller.
