Overflow grille with sound attenuation – 160 mm XL – RAL 9003
The Econox overflow grille is specially designed for the quiet transfer of air between adjacent spaces such as offices, meeting rooms, and sanitary areas. The overflow grille ensures constant air circulation and pressure compensation without direct supply or exhaust of outdoor air. Thanks to the integrated acoustic damping, sound transmission between rooms is minimised.
Practical information
The overflow grille has a diameter of 160 mm. The bayonet fitting and front parts are made from extruded aluminium, which prevents distortion during installation, and are then powder coated in RAL 9003.
Installation and applications
The overflow grille consists of two aluminium front parts with integrated sound-absorbing material and a bayonet fitting, allowing airtight installation in the wall. The grille can be easily fitted into a circular wall opening with a diameter of 160 mm.
