Research Products 6723 Rectangular Zone Damper 24V Spring Open

Product Description

The RESEARCH PRODUCTS 6723 is a rectangular zone damper designed for use in forced-air HVAC zoning systems. It features an aluminum frame and blade construction with a 2-wire electrical connection for straightforward wiring. The motor operates on 24 VAC at 60 Hz, draws 6 watts, and is rated at 12 volt-amperes. The damper uses a power-closed, spring-open motor configuration, meaning it closes on an applied 24-volt signal and opens automatically when power is removed. Licensed HVAC technicians install this damper during zoning system commissioning or as a replacement in existing zoned ductwork.

This zone damper is suited for residential and light commercial forced-air zoning applications. It mounts from the side, making it compatible with rectangular duct runs where inline installation space is limited. The spring-open fail-safe design ensures airflow is restored to the zone if power or signal is interrupted, which is a common requirement in zoning system design. It is typically installed in conjunction with a zone control board and low-voltage thermostat wiring.

Key Features

• Power-closed, spring-open motor provides fail-safe airflow on power loss
• 2-wire electrical connection simplifies low-voltage wiring
• Aluminum frame and blade for lightweight, corrosion-resistant construction
• Side mounting configuration for flexible duct installation
• Rated to 1 inch water column maximum static pressure
• Motor operates at 24 VAC, 60 Hz, 6 W, 12 VA

Compatibility

Designed as an OEM-style replacement for rectangular zone dampers used in residential and light commercial forced-air HVAC zoning systems requiring a 24 VAC, 2-wire, power-closed spring-open damper actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control board before installing or replacing the damper. Secure the damper in the duct with sheet metal screws and verify the 2-wire low-voltage connection matches the zone board output terminals. Confirm system operation by cycling each zone and checking that dampers open and close correctly before restoring full system operation.
