TRUaire GRD Accessories and Options

Multi-Shutter DampersFind all products with an optional multi-shutter damper

TruAire’s Multi-Shutter Dampers are the most common steel damper mechanisms used in our registers.  When you open and close the damper, the parallel blades move in unison, which affect airflow direction.


Opposed Blade DampersFind all products with an optional opposed blade damper

TruAire’s Opposed Blade Dampers are made of beautiful rock-solid aluminum and are an upgrade option for our registers.  OBD’s consist of paired rows of parallel blades that face, or “oppose” each other and the parallel blades open and close opposite of each other.  This creates a damper that controls and reduces the volume of the air without affecting airflow direction.

Radial DampersFind all products with an optional radial damper

TruAire’s Radial Dampers are made of circle-shaped steel and work exclusively on tbar commercial products.  Radial dampers consist of 3 or 4 sheet metal blades, fanned out to form the closed position.  In its open position these blades hide behind the front piece. Also referred to as a bow-tie damper, this damper is used in conjunction with the 2000 Series T-Bar Diffusers, particularly when the blades of the butterfly damper extend too far into the duct. Up to 14”. Click here for more information on the TRUaire 804 Radial Damper
