Grilles

Our wide selection of grilles, registers, diffusers, and accessories includes a variety of shapes and sizes to meet any application and budget requirement.

An effective HVAC system needs to be made up of the correct components, positioned perfectly in each room in a building to ensure an even air  distribution.

Grilles and Diffusers: What’s the difference?
Although grilles and diffusers job roles are similar, they do have some major differences.

Grilles can be used to either supply or return air, coming usually in a fixed blade. Grills are static and have fixed openings, the volume is constant as long as the fan volume is constant.

Grilles can be used for different applications and are often installed in vertical surfaces such as walls or doors.

Diffusers on the other hand can direct air in more directions than just up or down and, depending on the type of diffuser it is, can have several configurations which allow for multiple air pattern control.
