Heat Diffusers

Diffusers are used to distribute air evenly within your heating and cooling vents. They are designed to achieve better air mixing with less noise than standard registers and grilles. Diffusers are typically made of plastic, aluminum and steel and come in different styles like ceiling diffusers, plaque diffusers, cone diffusers and more. We’ve also got diffuser accessories like eggcrate grille panels, snap-on collars, return air grilles, backdraft dampers and flashing. Find everything you need to improve airflow in HVAC systems with diffusers, grilles and venting supplies from Zoro.
