Ewc Controls END-12X8 Motorized Zone Damper 12x8 24V

Product Description

The EWC CONTROLS END-12X8 is a 24-volt rectangular motorized zone damper designed for residential and light-commercial HVAC zoning applications. Part of the ND Ultra-Zone series, it features a side-mounted motor and a 3-wire connection to control airflow in ductwork as part of a multi-zone climate system. An onboard LED indicator lets technicians visually confirm damper position during commissioning without additional test equipment. The reinforced frame speeds up duct installation, and nylon bushings reduce operating noise for quieter long-term performance. Licensed HVAC technicians are the primary installers of this component.

The END-12X8 fits rectangular duct openings measuring 12 inches by 8 inches and is rated for air quality and zoning control applications. It is suited for new-construction zoning layouts and retrofit zone-control upgrades in forced-air systems. The 3-wire motor interface is compatible with standard zone control panels and thermostats that output a 24-volt signal. The LED display simplifies field checkout, reducing commissioning time and the likelihood of callback service calls.

Key Features

• LED indicator light for visual damper position verification during installation and checkout
• 24-volt, 3-wire motor connection compatible with standard zoning control panels
• Side-mounted motor design for accessible installation in tight duct chases
• Nylon bushings reduce mechanical noise during damper operation
• Reinforced rectangular frame for faster, more secure duct fitment
• Designed for air quality and zoning control in forced-air HVAC systems

Compatibility

Designed as an OEM-style replacement or new-installation damper for rectangular duct zoning systems requiring a 12-inch by 8-inch motorized damper with 24-volt control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and ductwork modification. Disconnect power to the air handler and zone control panel before wiring the damper motor. Verify the duct opening matches the 12-inch by 8-inch damper frame dimensions before securing to avoid air bypass. Follow the zone control manufacturer wiring diagram for proper 3-wire connection to prevent motor damage.
