HS-42 steel / stainless steel
Article number: 1003
The safety ventilation louvres type HS (High Safety) are specially designed for additional burglary protection when naturally ventilating transformer and gas spaces. Available with class 2 and class 3 burglar resistance certification according to NEN-5096 and EN-1627, this louvre retains its properties:
- rainproof (see test data)
- (dust) snow and dust resistant (see test data)
- safe-proof
- burglar-resistant WK2 WK3 RC2 RC3
- Flame-extinguishing
- mouse-tight
- maintenance-free
- one metallic whole for grounding
- vandal-proof
- condensate drain
As a result, people, animals, equipment and machines are optimally protected.
The various components of the JAZO air vents are assembled and welded at the front and / or rear. 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. Also available in stainless steel.
