Ventilation / grille elements made of steel

Franzen field elements

Ventilation and grille elements, which ensure permanent air exchange, offer additional protection. Depending on requirements, Franzen ISN-1 and Franzen ISN-2 internal doors and Franzen ASN-1 and Franzen ASN-2 external doors can be fitted with either gill ventilation, louvre ventilation or bar grilles.

With the steel ventilation elements, Franzen offers a further customisation option for doors & gates.

Louvre ventilation with enhanced burglar resistance

The louvre vents can be equipped with burglar resistance up to class RC4 in accordance with EN 1627-1630. They can be installed either in the corresponding Franzen ESN-1 burglar resistance doors or as a fixed ventilation element directly in the wall.

Franzen field elements with gill ventilation or bar grilles can be equipped with burglar resistance up to class RC2.

Individually configurable

The elements can also be equipped with additional options and are available in galvanised and primed, powder-coated versions. The louvre and gill vents are opaque, puncture-proof and rain-repellent. They can also be fitted with insect or bird screens.
