HJ-55 aluminium

The type HJ (Horizontal Jalousie) ventilation louvre is used in technical areas such as emergency power generator (UPS), combined heat and power (CHP), machine rooms, boiler houses and compressor buildings, with special requirements for air flow, low air resistance and rain resistance.

Characteristics:

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

The JAZO ventilation louvre type HJ 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. 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.
