Ewc Controls END-8X22 Nd Motorized Damper 8x22 in 24V

Product Description

The EWC CONTROLS END-8X22 is a rectangular motorized damper designed for HVAC zoning and air quality control applications. Measuring 8 inches by 22 inches, this damper accepts a 24-volt control signal and uses a 3-wire motor connection to modulate airflow through ductwork. The motor is bottom-mounted, and an integrated LED indicator light provides a clear visual reference for damper status during installation and service. Licensed HVAC technicians install this component as part of a zone control system to direct conditioned air where it is needed.

The END-8X22 is suited for residential and light commercial HVAC systems where zone dampers are used to balance or redirect airflow across multiple areas. Its rectangular profile fits standard rectangular duct openings at the 8-inch by 22-inch dimension, making it appropriate for trunk-line branch takeoffs and larger zone control runs. The 24-volt low-voltage control signal is compatible with typical zone control panels and thermostats used in forced-air zoning systems.

Key Features

• 24-volt operation compatible with standard HVAC zone control panels
• 3-wire motor connection for open, close, and common signals
• Bottom motor mount for installation flexibility in tight duct spaces
• Integrated LED indicator light for quick visual status confirmation
• Rectangular shape fits standard 8-inch by 22-inch duct openings

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular duct zoning systems operating on 24-volt low-voltage control circuits.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler and de-energize the zone control panel before connecting or disconnecting the damper motor wiring. Verify that the duct opening dimensions match the damper size before securing the unit in place. Follow all applicable local mechanical codes and manufacturer wiring diagrams when integrating the damper into the zone control system.
