Ewc Controls END-8X24-MA15S Nd Motorized Damper 8x24 in

Product Description

The EWC CONTROLS END-8X24-MA15S is a rectangular, non-spring-return motorized damper designed for zone control and air quality applications in ducted HVAC systems. Operating at 24 volts, it features a bottom-mounted motor that drives the blade to the open or closed position with a 15-second actuation time. The damper measures 8 inches by 24 inches and uses a 3-wire motor connection for straightforward integration with standard zone control boards. Licensed HVAC technicians install this component during zoned system commissioning, service, or retrofit work.

The END-8X24-MA15S is suited for residential and light commercial zoning applications where precise airflow regulation is required. Its rectangular profile fits standard 8-inch by 24-inch duct openings, making it a practical choice for multi-zone forced-air systems. The built-in LED indicator assists with visual status confirmation during installation and troubleshooting. Air quality control setups that require motorized zone dampers with reliable, repeatable actuation are a typical application for this unit.

Key Features

• 24-volt operation compatible with standard zone control low-voltage wiring
• 15-second motor actuation time for smooth, controlled blade movement
• 3-wire motor connection for integration with zone control boards
• Bottom-mounted motor for accessible installation in tight duct runs
• Built-in LED indicator for visual status confirmation
• Rectangular 8-inch by 24-inch profile fits standard rectangular duct openings

Compatibility

Designed as an OEM-style motorized zone damper for rectangular ducted HVAC zoning systems requiring 24-volt, 3-wire actuator control in air quality applications.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control board before wiring or mounting the damper. Verify duct opening dimensions match the damper frame before securing to avoid air bypass around the blade. Follow NEC low-voltage wiring guidelines when connecting the 3-wire motor leads to the zone control board.
