Research Products 6816 Rectangular Zone Damper with Motor

Product Description

The RESEARCH PRODUCTS 6816 is a rectangular zone damper with an integrated synchronous motor, designed for use in residential and light commercial HVAC zoning systems. Built from galvanized steel, the 6816 operates on a power-closed, spring-open actuator driven by a 24 VAC synchronous motor rated at 6 watts and 12 VA at 60 Hz. The bottom-mounting design and 1 inch water column pressure rating make it well suited for standard duct zoning installations. Licensed HVAC technicians and zoning system installers are the primary trade audience for this component. The damper measures 17-7/8 inches wide and 7.813 inches tall, covering common rectangular duct openings in both residential and light commercial applications.

The 6816 is intended for rectangular duct zoning applications in residential forced-air systems and light commercial installations where multiple zones require independent airflow control. The power-closed, spring-open motor configuration provides a fail-safe that defaults to the open position on power loss, which is a standard requirement in many zoning system designs. Galvanized steel construction holds up to the interior duct environment over extended service cycles. This damper is appropriate for installation within supply or return duct runs as part of a multi-zone control system.

Key Features

• Power-closed, spring-open synchronous motor provides fail-safe open position on power loss
• 24 VAC at 60 Hz motor operation for compatibility with standard low-voltage zoning controls
• Galvanized steel construction for corrosion resistance in duct environments
• Bottom-mounting design for straightforward integration into rectangular duct runs
• 1 inch water column pressure rating suitable for residential and light commercial systems
• Rectangular form factor at 17-7/8 inches wide by 7.813 inches tall covers a common duct size range

Compatibility

Designed as an OEM-style zone damper for rectangular duct zoning applications in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and duct modification work. Shut down the air handler and de-energize the 24-volt control circuit before connecting or disconnecting the motor wiring. Secure the damper body to the duct using sheet metal screws at the bottom-mount flanges per the manufacturer installation guide. Verify damper blade operation and spring-open function before restoring system power and confirming zone control sequence.
