Description
PZZN is an external louver. The product is intended to protect the outside supply and exhaust wall openings against
rain water penetration. 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 available
Design
PZZN is manufactured from galvanized steel sheet. The product consists of an outer frame, an inner frame with a build
in ledge, blades with 45 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. The build in ledge avoids water penetration across the louver
frame. The welded mesh screen is intended to block larger inpurities (e.g. leaves). The mounting frame contains screw
openings for easy installation into the end of a duct and bendable legs for easy installation into a wall.
