Ewc Controls END-10X8-MA15S Motorized Damper 8x10 in 24V

Product Description

The EWC CONTROLS END-10X8-MA15S is a rectangular motorized damper designed for HVAC zoning and air quality control applications. Operating at 24 volts, this damper uses a 3-wire motor mounted on the bottom of the unit to open and close the blade, regulating airflow through the duct. The 15-second motor cycle time allows for controlled, reliable actuation in ducted systems. An integrated LED indicator provides a visual status reference during operation. Licensed HVAC technicians typically install this component as part of a zone control system in residential or light commercial forced-air applications.

This damper fits an 8 x 10 inch rectangular duct opening and is suited for air quality and zoning installations where low-voltage motorized control of individual duct branches is required. It is commonly installed in zoned HVAC systems that use a zone control board or thermostat-based controller to manage airflow distribution to different areas of a building. The bottom-mount motor orientation should be accounted for during rough-in to ensure clearance for wiring and motor access.

Key Features

• 24-volt low-voltage operation compatible with standard zone control boards
• 15-second motor actuation cycle for controlled damper travel
• 3-wire motor connection for open, close, and common terminals
• Bottom-mount motor for specific installation orientations
• Integrated LED indicator for visual status during operation
• Rectangular shape sized for 8 x 10 inch duct openings

Compatibility

Designed as an OEM-style motorized damper replacement or new installation component for 8 x 10 inch rectangular duct systems using 24-volt zone control wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zone control systems. De-energize the HVAC system and zone control board before making any wiring connections. Verify motor clearance on the bottom-mount side before fastening the damper in the duct. Wiring should comply with applicable local codes and NEC guidelines for low-voltage HVAC control circuits.
