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 FAJ-402 is

* 691 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.
