The water is blocked from entering the duct with air speed up to 3 m/s. The product also blocks the view into the inside of the duct. The product is ideal for building facade ventilation transitions for air supply or extract.Highlights• Proven design for effective rain water separation• Robustness and mechanical stability• Vast colour and surface finish range availableDesignPZZNS is manufactured from galvanized steel sheet. The product consists of an outer frame, an inner frame with a build in ledge, blades with 90 mm spacing and can be equipped by an "S" welded mesh screen (raster 10 mm × 10 mm) and "UR" mounting frame. The product is provided without any additional surface finish as standard and can be powder painted to any RAL code specified by customer.
