Air-In® supply air valves and noise reducers increase the comfort of living and save energy.
Air-In® supply air valves and noise reducers offer superior noise reduction values and the draught-free air quantities.

OUTER GRILLES FOR THE AIR-IN® WALL VALVES

The Air-In® Outer grille is made of durable galvanised steel sheet of high quality. The outer grille allows the flow of air on both sides of the valve. It is installed bevelled side up, thereby preventing the entry of rain water in the structures.

The outer grille is available in all RAL colours, blending in with the other external structures of the house.

The same basic model of the Air-In® Outer grille can be used with all Air-In® Wall valves. Only the size of the installation ring changes according to the valve type.

AIR-IN® STORM GRILLE

The Air-In® Storm grille is manufactured for use as the outer grille of supply air valves in mechanical and gravitational ventilation systems. Our model suited for mechanical heat recovery systems is larger than the storm grille used for gravitational systems.

The structure of the storm-protected outer grille completely prevents the entry of water and snow into the lead-through duct. It also removes pressure shocks caused by wind and prevents draught caused by air flowing through the apartment.

The material is powder-coated, galvanised steel sheet.
