Greenheck SEH-202 Installation Manual
Sightproof Louver
Drainable Head
Application and Design
SEH-202 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 SEH-202 is an extremely efficient louver with
AMCA LICENSED PERFORMANCE DATA enabling designers to
select and apply with confidence.

Free area velocities (shown) are higher than average
velocity through the overall louver size. See louver selection

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-202 is 600 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.
