Ewc Controls END-14X10 Motorized Zone Damper 14x10 in

Product Description

The EWC CONTROLS END-14X10 is a rectangular motorized zone damper designed for residential and light commercial HVAC zoning systems. Operating at 24 volts, this ND-series damper controls conditioned airflow through ductwork to individual zones, allowing for independent temperature management across a structure. The unit features a side-mounted motor, nylon bushings for quieter operation, and an onboard LED indicator that lets the installer visually confirm damper position and operation during checkout. Three motor wires connect to the zone controller. The sturdier frame design is built for faster duct installation with fewer alignment issues.

This damper is suited for rectangular duct applications in zoned forced-air HVAC systems where airflow to individual rooms or areas must be modulated. At 14 inches by 10 inches, it fits standard rectangular duct openings of that size. Typical installations involve pairing this damper with a compatible zone control panel and low-voltage thermostat wiring. It is appropriate for air quality and comfort zoning applications in residential new construction and retrofit scenarios.

Key Features

• LED indicator light for visual confirmation of damper operation during installation and service
• 24-volt operation compatible with standard low-voltage HVAC zone control systems
• Nylon bushings reduce motor and blade noise during operation
• Side-mounted motor with 3-wire connection to zone controller
• Reinforced frame design for faster, more secure duct installation
• Rectangular form factor fits standard 14-inch by 10-inch duct openings

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular ducted HVAC zoning systems requiring a 14-inch by 10-inch damper with 24-volt low-voltage control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems and low-voltage control wiring. Power down the air handler and zone control panel before making any wiring connections. Verify duct dimensions match the damper opening size before securing the unit in the duct. Consult the zone controller manufacturer wiring diagram for proper 3-wire motor terminal assignments and confirm LED operation before closing the system.
