Model ESJ-401RM 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

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.
water penetration for Model ESJ-401RM is 658 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.
