HS-50 aluminium

Article number: 1004

The aluminium safety ventilation louvres type HS (High Safety) are specially designed for the natural ventilation of transformer rooms and gas rooms.

Characteristics:

  • rainproof
  • (dust) snow and dust resistant
  • sand-resistant
  • safe-proof
  • 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 JAZO ventilation louvre type HS consists of a frame and single horizontal blades , with a leak sill. Each blade is welded to the front and / or rear in the frame, creating a metallic whole that meets the requirements for the grounding of technical areas. One earth-litze is sufficient.

There are various types of framing profiles and frame for a variety of mounting options. This makes it possible to assemble in every architectural detail.
