Diffusers and Grilles

Diffusers and grilles are used to control and direct airflow in heating, ventilation, and air conditioning (HVAC) systems. Industrial diffusers (HVAC diffusers, diffuser dampers) are also used in industrial air-dispersion applications. Product categories include two-way diffusers, four-way diffusers, and radial vane diffusers. With each type of product, a rugged metal frame surrounds an array of vanes or blades. These blades are positioned to achieve the most effective airflow for the application. Each blade is held in place by its own tensioning device. Diffusers with single-skin blades and airfoil blades are commonly available.
