Diffusers - Systemair

Supply and return air diffusers are manufactured from extruded aluminium profiles or sheet steel.

The shaping of the diffusers depends on the scope of use and types of installation. Rectangular, circular, linear and other special designs are available.

Diffusers are available with fixed or adjustable air discharge shape and air flow resistance.

The diffusers can be equipped by optional accessories such as plenum boxes or deflectors.

Anodized satin finish or painted to RAL9003 as standard are suitable for most installations for high-end finish. Other colours can be ordered as well.
