Greenheck SEH-401 Installation Manual

Sightproof Louver

Drainable Head

Application and Design

SEH-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 horizontal Chevron style blades to provide maximum resistance to rain and weather. The SEH401 is an extremely efficient louver with AMCA LICENSED PERFORMANCE DATA enabling designers to select and apply with confidence.

Free Air Velocity

Model SEH-401 resistance to airflow (pressure drop) varies depending on louver application (air intake or air exhaust). Free area velocities (shown) are higher than average velocity through the overall louver size. See louver selection information.

Free Area Velocity

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 SEH-401 is 765 fpm free area velocity.

The beginning point of water

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.
