Floor air grilles ALF
A rectangular floor air supply or exhaust ventilation grille made of aluminium, with fixed vanes set at an angle of 15 degrees. The ALF ventilation grilles are designed for low- and mediumpressure ventilation systems. They may be installed directly in the floor as end elements of ventilation ducts.
The frame and stationary vanes (insert) of the grilles are made out of anodised aluminium in natural colour. On order, it is possible to varnish them in another RAL colour. The vanes under standard version are made out of the profile which allows shaping the air outflow under the angle of 15 degrees. In the optional version, the vanes may be made out of brass or stainless steel profiles enabling to shape the air outflow under the angle of 0 degrees.
