The RESEARCH PRODUCTS 6724 is a rectangular zone damper with an integrated synchronous motor, designed for residential and light commercial HVAC zoning systems. Built with an aluminum frame and blade construction with a galvanized finish, this damper operates on a power-closed, spring-open principle, meaning it closes under motor power and returns to the open position by spring action on power loss. The motor runs on 24 volts AC at 60 Hz, drawing 6 watts and 10 VA. Side mounting accommodates standard duct installations. Licensed HVAC technicians and zoning contractors install this damper as part of multi-zone forced-air systems.
The 6724 is suited for residential and light commercial forced-air duct zoning applications. Its rectangular shape fits standard rectangular duct openings where individual zone control is required. The flexible link design used in residential sizes accommodates minor misalignment during installation. This damper is a component in zoning control systems that divide a single air handler or furnace into independently controlled temperature zones, reducing energy use and improving comfort. It is appropriate for new construction and retrofit zoning projects in single-family and light commercial buildings.
Designed as an OEM-style replacement or new-installation zone damper for residential and light commercial rectangular duct zoning systems using 24-volt AC zone control panels.
Zone dampers are installed by licensed HVAC technicians as part of a complete zoning system including a zone control panel, thermostats, and bypass provisions. De-energize the air handler and zone control panel before wiring the motor leads. Refer to the zone panel manufacturer wiring diagram for proper connection of the 24-volt control circuit. Verify static pressure in the duct system does not exceed the 1 in-WC rating before commissioning.
