Ewc Controls END-10X18 Nd Motorized Damper 10x18 in 24V

Product Description

The EWC CONTROLS END-10X18 is a rectangular motorized damper designed to control airflow in HVAC zoning and air quality applications. Sized at 10 inches by 18 inches, this ND-series damper operates on 24 volts and features a bottom-mounted motor with a 3-wire connection. An integrated LED indicator light provides visual confirmation of damper status during setup and service. HVAC technicians install this unit as part of zone control systems to regulate conditioned air delivery to individual spaces, improving system efficiency and comfort management.

This damper is suited for residential and light commercial forced-air duct systems where zone control or air quality management is required. The rectangular profile fits standard rectangular ductwork at the specified 10-inch by 18-inch opening. It is typically installed by licensed HVAC technicians during new construction zoning projects or as a retrofit component in existing duct systems requiring added zone control capability.

Key Features

• 24-volt operation compatible with standard low-voltage HVAC zoning controls
• Rectangular shape sized at 10 inches by 18 inches for direct duct integration
• Bottom-mounted motor for accessible installation in confined duct spaces
• 3-wire motor connection for straightforward wiring to zone control boards
• Integrated LED indicator light for visual damper status confirmation

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular forced-air duct systems requiring 24-volt zone control or air quality management.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Disconnect and lock out power to the air handler and zone control panel before beginning installation. Ensure the duct opening matches the 10-inch by 18-inch damper dimensions before mounting. Follow the zone controller manufacturer wiring diagram when connecting the 3-wire motor lead to avoid damage to the motor or control board.
