WOODDRYER SYSTEM specification sheet.

Glass-fiber self closing louver.

Wooddryer System self closing louver is made of glass-fiber for maximum protection against corrosion. The louver is normally placed directly in front of the exhaust fan in the area with the most condensation and highest chance of corrosion. The blades on the louver are linked to insure proper closing, even with a small difference in static pressure on both sides of the louver. The louver should only be placed in front of an exhaust fan since the heavy duty design requires a higher than usual air pressure to open. This makes the louver very suitable to be placed by the exhaust fans
