Free Air Velocity
Model FSJ-402 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.
The beginning point of water penetration for Model FSJ-402 is
*
839 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.
