Ready-to-Connect Drop-Ceiling Diffusers

No additional fittings or collars needed—connect to round duct with the included collar. These diffusers fit in the grid of a drop ceiling to evenly disperse airflow and maintain a consistent temperature throughout the space.

Dampers with a butterfly opening/closing style open on a middle hinge. The removable handle adjusts the damper to control airflow and is easier to adjust than dampers with a radial opening/closing style.

Dampers with a radial opening/closing style open in a circle for more precise airflow than dampers with a butterfly opening/closing style.

Drop-Ceiling Diffusers

Diffusers

Grid

Perforated

Place these diffusers in the grid of a drop ceiling to evenly disperse airflow and maintain consistent temperature throughout the space. Connect to round duct with a snap-on collar (not included).

Grid diffusers are often used with cooling systems. They disperse a thin layer of air along the ceiling for even distribution.

Perforated diffusers have more openings than grid diffusers to release more air.

Ready-to-Connect Moisture-Resistant Drop-Ceiling Diffusers

A vapor barrier provides moisture protection as these diffusers evenly disperse airflow and maintain a consistent temperature throughout the space. No additional fittings or collars needed—connect to round duct with the included collar. Diffusers fit in the grid of a drop ceiling.

Diffusers with R-6 insulation thermal resistance maintain temperature more effectively than diffusers with R-1 thermal resistance.

Dampers with a radial opening/closing style open in a circle for more precise airflow than dampers with a butterfly opening/closing style.
