VS-42 steel / stainless steel

Article number: 1024

The safety ventilation louvre type VS (Vertical Safety), a vertically placed HS louvre, is suitable for the natural ventilation of transformer rooms and other technical areas. The louvre has the additional advantage that the water resistance is even better. The types of VS louvres are very suitable for placement in an inclined roof surface. Available with burglar-resistance certification RC3, this louvre retains its properties:

  • rainproof
  • (dust) snow and dust resistant
  • safe-proof
  • burglar-resistant RC3
  • flame-extinguishing
  • mouse-tight
  • maintenance-free
  • one metallic whole for grounding
  • vandal-proof and condensate-draining

    As a result, people, animals, equipment and machines are optimally protected.

The various components of the JAZO air vents are combined and completely welded. As a result, a metallic whole is created, as a result of which requirements with respect to grounding can be met in a simple manner. One earth-litze is sufficient. There is a choice of various types of framing profiles. Mounting the ventilation louvre is possible in every architectural detail.
