Swirl Diffuser – Floor Aluminium (SDFA)

Swirl Diffuser – Floor Aluminium (SDFA)




The SDFA swirl diffuser floor aluminium combines a robust floor grille with a swirl effect diffuser, which is suitable for cooling or heating on supply or exhaust air systems.

The diffuser face incorporates a series of straight slots, which provides a high induction swirl air pattern and with a low plenum pressure, making it ideal for most applications under pressurised under-floor air distribution systems.

The inner grille section is removable for access and maintenance.

Cleverly incorporated into the design is a manual air damper, which is easily adjusted by simply rotating the diffuser face.

The SDFA is supplied in a standard nominal size of 200mm diameter.


The SDFA is constructed from high quality linished aluminium material.
