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.
