3085NM: OBD w/Plate (Controls by Others)

Submittal Form


The Young Regulator 3085-NM is an opposed blade rectangular damper designed for low pressure, forced air, HVAC systems. A 5″ wide plate with an extended shaft makes this an ideal solution for control contractors to install their own actuator and HVAC controls. Individual synthetic blade bushings provide smooth, quiet operation for the life of the damper. This is a high free area damper for lower pressure drop across the damper.
The damper is only 2 1/8″ wide with the blades contained within the frame, ideal where space limited. It is easily installed into the duct work by cutting a 2 1/4″ slot and slipping the damper inside. The damper is secured to the side of the duct with 4 screws.
