RON 410 is used in locations with particularly harsh climates (hurricanes, blizzards). The extra-strong welded construction provides maximum protection for ventilation shafts. It has the highest free area ratio among all external ventilation grilles.

Design

Rigid welded construction of sheet steel (stainless and cold-rolled steel) or aluminium. A perimeter flange is provided for wall mounting. Can be equipped with a self-regulating heating cable.

Coating

Painting is carried out by powder coating at the factory in colours from the international RAL scale. The polyester coating reliably protects the aluminium from oxidation and the paint itself from fading.

Size

Minimum recommended size 300x300 mm. Maximum recommended size 2000x2000 mm.

Installation

Surface-mounted, fixed through the grille flange
