Frequently Asked Questions

What is the purpose of a ventilation grille with a pre-frame?

The ventilation grille allows for the renewal of stale air in a room and connects spaces to ventilation systems or ducts. The inclusion of the pre-frame is essential because it is installed first in the wall or duct, allowing the grille to be fixed cleanly and securely, as well as facilitating its subsequent removal for cleaning.

Can it be installed outdoors?

Although it features a durable metal finish, this model is primarily designed for indoor use. If you wish to place it outdoors, it is recommended to ensure it is not exposed to direct and constant harsh weather conditions to preserve its gray finish.

How is cleaning and maintenance performed?

Thanks to its pre-framed design, the grille can be easily removed. It is recommended to clean it periodically with a damp cloth and mild soap to remove accumulated dust, avoiding the use of abrasive products that could damage the metallic paint.
