The aluminum safety ventilation grilles type HF (High Flow) are specially designed for the forced ventilation of technical rooms.
Characteristics:
• maintenance free

• vandal-proof and condensate-draining
This ensures optimum protection for people, animals, equipment and machines.
The JAZO ventilation grille type HF consists of a frame (frame) and single horizontal vanes (slats), with a leak sill. Each paddle is welded to the rear, creating a metallic whole that meets the requirements for the earthing of technical spaces. A single earth suffices.
