Research Products 6827 Rectangular Zone Damper 24V

Product Description

The RESEARCH PRODUCTS 6827 is a rectangular zone damper designed for use in residential and light commercial HVAC zoning systems. It features an aluminum frame and blade construction with a power-closed, spring-open motor that operates on 24 VAC at 60 Hz, drawing 6 watts and 12 volt-amps. The 2-wire electrical connection simplifies wiring to zone control boards, and bottom mounting hardware allows straightforward installation into ductwork. This damper is installed by licensed HVAC technicians as part of a multi-zone forced-air system, where individual zones require independent airflow control to meet varying load demands.

The 6827 is suited for rectangular duct applications in zoned forced-air heating and cooling systems. The spring-open, power-closed motor configuration means the damper defaults to the open position when power is removed, which is a common fail-safe design in residential zoning applications. It is rated for a maximum static pressure of 1 inch water column, making it appropriate for typical residential forced-air ductwork operating pressures. HVAC contractors install this damper in trunk lines or branch ducts as directed by the zone control system layout.

Key Features

• Power-closed, spring-open motor defaults to open position on power loss for fail-safe airflow
• 24 VAC at 60 Hz motor operation compatible with standard low-voltage HVAC zone controllers
• 2-wire electrical connection simplifies integration with zone control boards
• Aluminum frame and blade construction for lightweight, corrosion-resistant performance
• Bottom mounting design for straightforward duct installation
• Rated to 1 inch water column maximum static pressure for residential duct systems

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular duct zoning applications in residential and light commercial forced-air HVAC systems using 24 VAC zone control wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control panel before wiring or mounting the damper. Ensure the duct opening matches the damper frame dimensions before securing with bottom mount hardware. Follow applicable mechanical and electrical codes, including NEC low-voltage wiring requirements, when connecting the 2-wire motor lead to the zone control board.
