The recessed core diffuser is used for horizontal air distribution whilst the flush face style is more suitable for vertical air distribution when mounted at higher levels.

GDL's range of high-quality displacement diffusers are designed to introduce cool clean air into the occupied zone at low level.

The diffuser includes an integral baffle, which can be adjusted to provide horizontal or vertical discharge patterns.

Rapid air velocity and temperature differential reduction allows high air changes whilst maintaining comfort criteria in the occupied zone.

The diffuser offers both discreet ceiling integration and excellent performance unique to swirl diffusers.

Its adjustable vanes offer the flexibility required to overcome problems with the supply of warm and cool air into a modern office application.

Adjustable vanes offer the flexibility required to overcome problems with the supply of warm and cool air into a modern office application.

The rapid reduction in both air velocity and temperature differential lead to very comfortable conditions within the occupied zone.

Essential for operating theatres, laboratories and clean rooms. Suitable for ceiling mounting in multiple units.
