Ewc Controls END-8X18 Nd Motorized Damper 8x18 in 24V

Product Description

The EWC CONTROLS END-8X18 is a rectangular motorized damper designed to control airflow in HVAC zoning and air quality applications. Measuring 8 inches by 18 inches, this damper operates on 24 volts and connects to the motor via a 3-wire harness. The bottom-mounted motor and integrated LED indicator light make wiring verification and system diagnostics straightforward during installation and service. HVAC technicians install this damper in ductwork as part of a zone control system, allowing independent airflow regulation to different areas of a building.

The END-8X18 is suited for residential and light commercial HVAC systems where air quality control and zone damping are required. Its rectangular profile fits standard rectangular duct openings at 8 by 18 inches. The 24-volt control signal is compatible with typical low-voltage zone control boards and thermostats commonly found in forced-air systems. This damper is appropriate for new installations and retrofit zoning projects in ducted air distribution systems.

Key Features

• Rectangular damper sized at 8 inches by 18 inches for standard duct fitment
• 24-volt operation compatible with low-voltage zone control systems
• 3-wire motor connection for straightforward wiring to zone controllers
• Bottom-mounted motor for accessible installation and servicing
• Integrated LED indicator light for visual status confirmation
• Designed for air quality and zone airflow control applications

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular duct systems requiring 24-volt zone control in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage control wiring and duct system design. Power down the zone control panel and air handler before making any wiring or duct connections. Ensure the damper is mounted with the motor in the bottom position as specified and that the 3-wire harness is routed clear of sharp duct edges. Follow applicable mechanical codes and the zone controller manufacturer wiring guidelines when integrating into an existing or new zoning system.
