Installation

The installation is performed by opening the special brackets present in the subframe or alternatively by fixing the latter to the wall or duct using screws.

EGQ1 - EGQ2: only for wall installation, ceiling installation is not recommended; closing by magnets.

EGQ3 - EGQ4: Closing with a screw.

Use

Suitable for the extraction of air.
Its nice design and the great effective section make it ideal in civil environment installation.
We recommend not to exceed the front speed of 1,5 m/s. Initial pressure drop lower than 40Pa.

Models

EGQ1: grille with filter;
EGQ2: grille with filter and damper;
EGQ3: grille with special counterframe fixed with hinges to the frame of the grille which allows a 80° opening for the easy maintenance of the filter;
