Greenheck SED-401 Installation Manual

Sightproof Louver

Drainable Blade

Application and Design

SED-401 is a sightproof weather louver designed to protect air intake and exhaust openings in building exterior walls when visual see through prevention is needed. Design incorporates a drainable head member and drainable horizontal Chevron style blades to channel water to the jambs which guides the water through vertical downspouts for escape at the sill. The SED-401 is an extremely efficient louver with AMCA LICENSED PERFORMANCE DATA enabling designers to select and apply with confidence.

The AMCA Water Penetration Test provides a method for comparing various louver models and designs as to their efficiency in resisting the penetration of rainfall under specific laboratory test conditions. The beginning point of water penetration is defined as that velocity where the water penetration curve projects through .01 oz. of water (penetration) per sq. ft. of louver free area.

penetration for Model SED-401 is 747 fpm free area velocity.

These perfor mance ratings do not guarantee a louver to be weather proof or stormproof and should be used in combination with other factors including good engineering judgement in selecting louvers.
