The type HF (High Flow) ventilation louvre is used in technical rooms, such as in emergency power generator (UPS) rooms and combined heat and power (CHP) rooms, engine rooms, boiler houses and compressor buildings, where special requirements are set for air flow, low air pressure build-up, but where rain resistance is less important.

  • vandal-proof
  • water-retaining
  • low maintenance and one metallic unit for grounding

The JAZO ventilation louvre type HF consists of a frame and single horizontal blades with a leak seal at the bottom. Each blade is completely welded in the frame, creating a metallic whole that meets the requirements for the grounding of technical areas. There are various types of framing profiles and frame with a variety of mounting options. This makes it possible to assemble in every architectural detail.
