Research Products 6108 Barometric Pressure Relief Damper

Product Description

The RESEARCH PRODUCTS 6108 is a round barometric pressure relief damper designed to equalize static pressure in forced-air duct systems. When duct pressure rises above a set threshold, the damper opens to relieve excess pressure and protect equipment from over-pressurization. Standing at 10.75 inches in height, this round-profile damper fits standard residential and light commercial duct installations. It is typically installed by licensed HVAC technicians during system commissioning or duct modification work.

The 6108 is suited for use in residential and light commercial forced-air HVAC systems where balanced static pressure is critical to system performance and equipment longevity. It is commonly installed in supply or return duct runs where zoning, variable-speed equipment, or tight duct configurations create pressure imbalances. The round shape allows direct integration into circular duct runs without adapters in many standard configurations.

Key Features

• Round profile for direct integration into circular duct runs
• Barometric relief action responds passively to duct pressure changes without powered actuation
• 10.75-inch height accommodates standard residential duct system profiles
• Helps protect HVAC equipment from over-pressurization in zoned or variable-speed systems

Compatibility

Designed as an OEM-style barometric pressure relief damper for residential and light commercial forced-air duct systems requiring passive static pressure management.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler or furnace and set the thermostat to off before working on the duct system. The damper should be mounted in a section of ductwork accessible for future inspection and cleaned of debris before fitting. Follow local mechanical codes and ACCA Manual D guidelines when sizing and positioning pressure relief components in the duct system.
