Braeburn Systems 119114 Static Pressure Bypass Damper 14 Inches Diameter X 13.75 Inches Length

Product Description

The Braeburn Systems 119114 is a static pressure bypass damper designed for use in residential and light commercial HVAC duct systems. It measures 14 inches in diameter and 13.75 inches in length. HVAC technicians and installers use this damper to relieve excess static pressure in zoned duct systems. When zones close off, static pressure builds up in the supply duct. Without a bypass solution, that pressure can strain the blower, reduce system efficiency, and shorten equipment life. The 119114 opens automatically when pressure rises above the set threshold and redirects excess air back to the return side of the system or to an unconditioned space. This protects the air handler and keeps the system balanced. The damper uses a weighted arm sensor to detect pressure changes. No wiring, no control board, and no external sensors are required. The weighted arm responds directly to airflow pressure and adjusts the damper blade position on its own. This makes installation faster and eliminates the risk of wiring errors. The blade can be fine-tuned through a fully adjustable control, allowing the damper to be set to open at the correct pressure for the specific system. Long life precision bushings support smooth, consistent blade movement over years of use. Stiffening ribs are built into the damper body to add rigidity and resist flex under high airflow conditions. The unit is constructed from heavy gauge galvanized steel for durability in both supply and return duct applications. It can be mounted vertically or horizontally, and airflow direction can be set to left or right, giving installers flexibility in tight mechanical spaces. A high visibility damper position indicator lets technicians confirm blade status during setup and service without guessing or using additional tools. This bypass damper is a reliable, passive solution for static pressure management in zoned HVAC installations.

• Passive weighted arm sensor requires no wiring or external controls
• Fully adjustable blade control supports precise static pressure calibration
• Mounts vertically or horizontally with left or right airflow direction
