Ewc Controls END-8X12 Nd Motorized Damper 12x8 in 24V

Product Description

The EWC CONTROLS END-8X12 is a rectangular motorized zone damper designed for HVAC air distribution systems requiring precise airflow control. Operating on 24 volts, this damper features a 3-wire motor connection with side motor mounting and includes an LED indicator that allows technicians to visually confirm damper position and operation status during setup and commissioning. The reinforced frame is engineered for faster duct installation, and nylon bushings at the pivot points reduce mechanical noise during operation. Sized at 12 inches by 8 inches, it fits standard rectangular duct openings in residential and light-commercial zoning applications.

The END-8X12 is intended for use in HVAC zoning systems where individual zones require independent airflow modulation. It is well suited for air quality and comfort zoning installations in residential ductwork. Licensed HVAC technicians typically install this damper as part of a multi-zone control system, integrating it with a compatible zone control board and low-voltage thermostat wiring. The LED status indicator simplifies field checkout and reduces diagnostic time after installation.

Key Features

• LED indicator light for visual confirmation of damper position during installation and checkout
• 24-volt operation compatible with standard low-voltage HVAC zoning controls
• 3-wire motor connection with side motor mount configuration
• Nylon bushings for reduced mechanical noise and extended motor service life
• Reinforced rectangular frame for faster, more secure duct installation
• Rectangular shape fits standard 12-inch by 8-inch duct openings

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular HVAC duct systems using 24-volt zone control equipment.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Disconnect power to the air handler and zone control board before mounting or wiring the damper. Secure the damper in the duct according to manufacturer orientation markings, and verify LED status indication before closing up the duct. Follow applicable mechanical and electrical codes, including NEC low-voltage wiring requirements, during field wiring of the 3-wire motor connection.
