EDFLB-FL Linear diffusers for air extraction with slot and filter
Description
The EDFLB-FL series diffusers are designed exclusively for return air applications in environments with large surface areas and relatively low ceiling heights.
They are equipped with an internal filter, secured by magnetic fixing, and are suitable for air extraction in offices, open-plan spaces, banks, large hotel lobbies, business centers, retail stores, courthouses, and similar applications.
The diffusers are manufactured from extruded aluminum profiles, engineered to achieve a highly aerodynamic and aesthetically refined design. Standard lengths are 800, 1000, 1500, and 2000 mm, available with a minimum of 3 and a maximum of 4 slots.
The standard finish is painted in RAL 9016; upon request, other रंग finishes are available using epoxy powder coating, electrostatically applied and oven-cured. This type of coating ensures high resistance to impact and abrasion, maintaining its aesthetic properties over time.
The diffuser is fixed to the plenum by means of concealed mounting bridges. It is equipped with dedicated internal tabs within the blade assembly, allowing the core to be opened like a hinged panel, enabling filter replacement without removing the entire diffuser.
