J Blade

Application and Design

ESJ-401LT is a weather louver designed to protect air intake and exhaust openings in building exterior walls. Design incorporates J style blades, sloped sill and high free area to provide maximum resistance to rain and weather while providing minimum resistance to airflow. The ESJ-401LT is an extremely efficient louver with AMCA LICENSED PERFORMANCE DATA enabling designers to select and apply with confidence.

Free Air Velocity

Model ESJ-401LT 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.

penetration for Model ESJ-401LT 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.
