Gypsum Circle Diffusers

£ 70.00 (excl. VAT)

£ 84.00 (inc. VAT)

For an almost invisible requirement, frameless PCIRCLE diffusers are probably the most versatile solution, blending perfectly with the environment.

They can be plastered together with the wall or the ceiling and can be painted with the same paint as the entire surface.
The diffuser cap is supported by magnets that do not lose their strength for 95 years.

Can be used for both air supply and air extraction.

Suitable for plasterboard ceilings or walls. Once installed, the diffuser forms a permanent bond with the plasterboard, offering outstanding durability. It can be sanded and painted just like the surrounding surfaces. It leaves no visible frames or flanges between the diffuser and the surrounding surface, making it ideal for very clean and modern interior design styles.
Two slot versions also available for 160 & 200mm, ask for details.
Constructed from a gypsum composite body with industrial strength internal magnets, steel connector, rubber gasket and elastic fixing strap.
45mm diffuser depth.
Suitable for short throw applications..
Includes screws, fixing strap and plastic spacers.

The PCIRCLE version encourages a more lateral air distribution using the Coanda effect in its design. The standard CIRCLE version does not have this design feature.

Available in 100/125/160/200 connector diameters.
