Sightproof Louver

Application and Design

SES-202 is a sightproof louver designed to protect air intake
and exhaust openings in building exterior walls. Design
incorporates Chevron style blades to prevent maximum
resistance to visual see through. The SES-202 is an extremely
efficient louver with AMCA LICENSED PERFORMANCE
DATA enabling designers to select and apply with confidence.

Free Air Velocity

Model SES-202 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

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 SES-202 is 516 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.
