Transfer Grille with Sound Attenuation – 100/125/160 mm – RAL 9003

The Econox transfer grille is specially designed for the quiet airflow transfer between adjacent spaces such as offices, meeting rooms, and sanitary areas. The transfer grille ensures constant air circulation and pressure balancing without direct air supply or exhaust from outside. Thanks to the integrated acoustic attenuation, sound transmission between rooms is minimised. This model has an effective diameter of 160 mm, making it universally compatible with wall openings of 100, 125, and 160 mm.

Practical Information

The transfer grille has a diameter of 160 mm, allowing the same grille to fit round wall openings of 100, 125, or 160 mm. The front panels and bayonet lock are made of galvanized steel, powder-coated in RAL 9003 as standard. The insulation has a cleanable surface coating and consists of 100% recycled, hypoallergenic, and water-repellent PET material.

Installation and Applications

The transfer grille consists of two front panels with integrated sound-absorbing material and a bayonet lock, enabling airtight installation within the wall. As the grille fits wall openings of 100, 125, and 160 mm, this single model covers multiple project sizes without compromising the appearance.
