Linear retracting diffuser in anti-condensate PVC with damper, insulated plenum and side baffles

Project Wind
Air diffusion

Linear retracting diffuser in anti-condensate PVC with damper, insulated plenum and side baffles. Available with 20 or 30 mm slot in black or white.
With a unique, original design, the plenum is made of galvanised metal sheet coated with closed-cell polyethylene.
This retracting linear diffuser combines design and function, blending perfectly into any room, with uniform air diffusion and high thermal induction.
This innovative diffuser is made from PVC which, in contrast to aluminium, due to its physical characteristics does not produce condensate; this avoids the formation of fungi, mould and bacteria inside the diffuser and ensures excellent wall insulation.
The inlet collars are included in the pack are must be assembled according to installation needs.
The plenum has other built-in installation boxes for additional ducts and MVHR ducts, break as needed.
The damper is used to control the required amount of air and can be calibrated using a screwdriver.
Housings are obtained from inside the profiles to enable the mounting of adjustable PVC baffles.
