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.
