Industrial weather grilles

The PŽA-P II industrial weather grille consists of a frame and individual blades. The frame is made of thin-walled profiles, profile blades are attached to the side frame. Larger grilles have partitions inserted between the individual rows of blades. The grilles can be installed in the pipes or by means of a wall frame in the wall. The weather grilles protect the outdoor intake and exhaust openings of ventilation equipment or ventilation openings of buildings and machinery. If necessary, the grilles can be supplemented with a screen against the entry of dirt (metal or nylon).

The grilles are used in all types of ventilation equipment. The maximum recommended air speed in the flow area is up to 6 ms-1.
