Research Products 6812 Rectangular Zone Damper with Motor

Product Description

The RESEARCH PRODUCTS 6812 is a rectangular zone damper with an integrated synchronous motor, designed for zoned HVAC distribution systems in residential and light commercial applications. The damper operates on a power-closed, spring-open actuation sequence, meaning the motor drives the blade to the closed position and the spring returns it to open on power loss — a fail-safe configuration common in residential zoning. The motor runs at 24 volts AC at 60 Hz, drawing 6 watts and 10 VA. The frame and blade are constructed from aluminum with a galvanized finish for corrosion resistance in ductwork environments. Licensed HVAC technicians and sheet metal contractors are the primary installers of this component.

The 6812 is suited for residential zoning installations and light commercial HVAC systems where rectangular duct configurations are used. It mounts from the bottom of the duct section. The power-closed, spring-open design integrates with standard 24-volt zone control boards, making it compatible with conventional residential zoning panels that switch low-voltage power to open or close individual zones. The aluminum frame and blade construction keep the assembly lightweight while maintaining structural integrity in forced-air duct systems.

Key Features

• Power-closed, spring-open actuation provides fail-safe open operation on loss of 24-volt control signal
• Synchronous motor rated at 24 volts AC, 60 Hz, 6 watts, 10 VA for compatibility with standard zone control transformers
• Aluminum frame and blade construction with galvanized finish for durability in ductwork
• Rectangular shape fits standard rectangular duct configurations used in residential and light commercial systems
• Bottom-mounting design for straightforward installation in accessible duct runs
• Pressure rating of 1 inch water column (in-WC) suitable for residential forced-air system static pressures

Compatibility

Designed as an OEM-style zone damper replacement or new installation component for residential and light commercial rectangular duct zoning systems using 24-volt AC control wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut off the air handling unit and de-energize the 24-volt control circuit at the zone panel or transformer before making wiring connections. Verify duct dimensions match the damper frame size before mounting, and secure the unit per local mechanical codes. Do not apply power to the motor outside the specified 24-volt AC, 60 Hz supply to avoid motor damage.
