Available43 products
HVAC diffusers install onto the ends of ducts and help spread conditioned air throughout a room. Some diffusers feature vents that create smooth airflow that travels along walls and ceilings before mixing with the interior air. Other diffusers use an array of small openings to disperse and mix the conditioned air into the interior space. This lowers the number of vents needed to regulate air quality and reduces the parts and labor to install them. Diffusers can be square or round, depending on the desired interior appearance.

Square Cone Diffusers
Square cone diffusers distribute conditioned air by forcing it through an array of narrow vents. As the air passes through these openings, it is focused and projects further into the interior space. This helps mix the conditioned air and spread it over a greater area than standard HVAC vents or registers.

Square Plaque Diffusers
Square plaque diffusers spread conditioned air through an interior space by channeling it through a narrow opening around their perimeters. Compared to a cone or perforated diffuser, they have a much cleaner appearance that blends in with the ceiling while offering similar performance.
