Research Products 6819 Rectangular Zone Damper 24V

Product Description

The RESEARCH PRODUCTS 6819 is a rectangular zone damper designed for use in residential and light commercial HVAC zoning systems. It controls airflow through ductwork by opening and closing on command from a zone control panel or thermostat. The damper uses a power-closed, spring-open motor rated at 24 VAC, 60 Hz, 6 watts, and 12 volt-amperes, with a 2-wire electrical connection that simplifies wiring at the damper. The aluminum frame and blade construction keeps the assembly lightweight while providing durable airflow control across multiple zones. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system.

This damper is suited for rectangular duct installations in residential forced-air zoning applications and light commercial systems requiring individual zone control. The bottom mounting configuration positions the motor on the underside of the duct, which is a common requirement in horizontal duct runs where access is needed from below. The spring-open motor design means the damper defaults to the open position on power loss, which is a standard fail-safe configuration in residential zoning. Maximum static pressure rating is 1 inch water column (in-WC), consistent with typical residential and light commercial duct system operating conditions.

Key Features

• Power-closed, spring-open motor provides automatic fail-safe open position on power loss
• 2-wire electrical connection reduces wiring complexity at the damper location
• Aluminum frame and blade construction for lightweight, corrosion-resistant durability
• Rated for 24 VAC at 60 Hz, compatible with standard low-voltage HVAC control systems
• Bottom mounting configuration for horizontal duct installation
• 1 inch water column maximum pressure rating suits residential and light commercial duct systems

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Disconnect power to the air handler and zone control panel before wiring or mounting the damper. Ensure the duct opening matches the damper frame dimensions before securing the unit in the bottom-mount position. Wiring should comply with NEC low-voltage requirements and the zone control manufacturer's wiring diagram.
