Round Aluminium Wall Vent with Fixed Grille – 400 mm – RAL 9003

The round Econox wall vent, made from aluminium and featuring a fixed grille, is specifically designed for air extraction in commercial interior spaces such as offices, schools, and retail outlets. The fixed grille ensures a stable, consistent, and predictable air distribution.

Practical Information

The wall vent has a diameter of 400 mm. The mounting frame is made from galvanized steel, and the grille is crafted from extruded aluminium, preventing deformation during installation, then powder-coated in RAL 9003.

Installation and Applications

The grille has a free passage area of 92% and is equipped with an EPDM sealing ring on the air connection, providing an airtight and vibration-free connection to the ventilation duct—without the need for additional tape or sealant. The vent can be easily installed in a round wall opening with a diameter of 400 mm.
