Ewc Controls END-8X24 Nd Motorized Damper 8x24 in 24V

Product Description

The EWC CONTROLS END-8X24 is a rectangular motorized damper designed for zone control and air quality applications in forced-air HVAC systems. Measuring 8 inches by 24 inches, it operates on 24 volts and connects to the actuator motor via a 3-wire configuration. The motor mounts on the bottom of the damper assembly, and an onboard LED indicator provides a clear visual status reference during commissioning and troubleshooting. Licensed HVAC technicians typically install this damper as part of a zoned duct system to regulate airflow to individual areas of a building.

This damper is suited for rectangular duct runs in residential and light commercial zoning systems where independent room or zone control is required. It is typically installed in main trunk lines or branch ducts as part of an air quality or zone control strategy. The 24-volt operating voltage makes it compatible with standard low-voltage zone control panels and thermostats commonly used in multi-zone HVAC installations.

Key Features

• Rectangular form factor sized at 8 inches by 24 inches for standard duct fitment
• 24-volt operation integrates with low-voltage zone control panels
• 3-wire motor connection supports standard open/close or modulating control wiring
• Bottom motor mount provides accessible actuator placement in tight duct runs
• Onboard LED indicator aids commissioning and status verification
• Designed for air quality and zone control applications

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zone control wiring and duct modification. Shut down the air handler and de-energize the zone control panel before cutting into ductwork or connecting wiring. Secure the damper frame to the duct with sheet metal screws and verify the motor mount orientation matches the installation clearances. Confirm damper blade travel is unobstructed and LED status is active before restoring system power.
