Research Products 6824 Rectangular Zone Damper 24V 2-wire

Product Description

The RESEARCH PRODUCTS 6824 is a rectangular zone damper designed for forced-air HVAC zoning systems. It controls airflow to individual zones by opening and closing on demand, allowing independent temperature control in different areas of a building. The damper uses a power-closed, spring-open motor rated at 24 VAC, 60 Hz, 6 watts, and 12 volt-amps, which means the damper fails open on power loss — a fail-safe characteristic important in zoning applications. The aluminum frame and blade construction provides durability in ductwork environments. Installation requires a 2-wire electrical connection to a zone control panel or thermostat output. Licensed HVAC technicians are the intended installers for this component.

This zone damper is suited for residential and light commercial forced-air zoning applications where rectangular duct sections are used. It mounts from the bottom of the duct and integrates with standard 24-volt zoning control panels. The spring-open motor design ensures that airflow is maintained to the zone if power is interrupted, which supports safe and compliant system operation. Typical installations include multi-zone ducted systems where airflow must be modulated room by room or zone by zone based on thermostat demand.

Key Features

• Power-closed, spring-open motor ensures fail-open operation on power loss
• 24 VAC motor rated at 6 watts and 12 volt-amps for compatibility with standard zone control panels
• Aluminum frame and blade construction for lightweight, corrosion-resistant performance in ductwork
• 2-wire electrical connection simplifies wiring to zone controllers
• Bottom-mounting configuration for straightforward duct installation
• Maximum pressure rating of 1 inch water column (in-WC)

Compatibility

Designed as an OEM-style replacement or new-installation rectangular zone damper for 24-volt forced-air HVAC zoning systems using standard zone control panels.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoning system wiring and ductwork practices. Shut off power to the zone control panel and air handler before installing or replacing the damper. Verify that the duct pressure in the application does not exceed 1 inch water column to stay within the rated operating range. Follow local mechanical codes and the zone control panel manufacturer's wiring instructions when making low-voltage connections.
