EDFL/B-FL Linear diffusers for air extraction with slot and filter

Home General catalogue Air Diffusion Air Diffusers Edfl B Fl Linear Diffusers For Air Extraction With Slot And Filter

Description:

“Diffusers of EDFL / B-FL serie can be exclusi­vely used for air extraction in environments that also have very large surfaces, but with relatively limited heights. They have a filter inside and the fixing is by magnets and they are used to extract the air from offices, open spaces, banks, lar­ge halls of hotels, business centers, shops, courts, etc.
They are built using extruded aluminium profiles to obtain an highly aerodynamic and aesthetically pleasing design, with standard lengths of 800-1000-1500- 2000 mm for a minimum of 3 and a maximum of 4 slots. The standard painting is RAL 9016 and, on request, they can be painted with other colours, with powders based on epoxy resins placed electrostatically and dried in the oven. This kind of painting is resistant to any impact and abrasion, and maintains its aesthetic characteristics over time. The fixing of the diffuser to the plenum is carried out using non-visible moun­ting bridges. The diffusers are provided with special tabs inside the fins pack that allow a “book opening” to replace the filter without dismantle the whole diffuser.
