Multi-Cone Diffuser (Fixed and Adjustable) -


An attractive air diffuser for open plan areas


With excellent air handling capabilities, Multi Cone Diffusers are best suited to applications in airport terminals, warehouses and other large open plan areas.

With regard to mounting, Multi Cone Diffusers can be fitted into conventional ceilings and connected into ventilation systems with flexible ducting, or mounted to the end of rigid spiral ducting.

The aerodynamic design of internal components ensures the dreaded organ pipe effect is avoided, for the comfort of occupants.

Comfort is furthered using the special design of the internal cones and their mounting mechanisms. In much the same way as Air Valves, Multi Cone Diffuser cores can be screwed in to provide a targeted downward throw, or screwed out creating a traditional sideways throw.

Multi Cone Diffusers are standard finished in RAL9010 White with stove enamel paint.  Can be powder coated to any RAL/BS colour.
