SED-501
Application and Design
SED-501 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-501 is an extremely efficient louver with AMCA
LICENSED PERFORMANCE DATA enabling designers to select and
apply with confidence.

Test size 48 in. x 48 in. Test duration of 15 min.
Model SED-501 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.
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.
*
The beginning point of water
penetration for Model SED-501 is 1134 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.
