Greenheck ESD-403LT Installation Manual
Stationary Louver
Drainable Blade
Application and Design
ESD-403LT is a weather louver designed to protect air intake and
exhaust openings in building exterior walls. Design incorporates
a drainable head member and stationary horizontal blades to
channel water to the jambs which guides the water through vertical
downspouts for escape at the sill. The ESD-403LT is an extremely
efficient louver with AMCA LICENSED PERFORMANCE DATA
enabling designers to select and apply with confidence.

Free Air Velocity
Model ESD-403LT 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 ESD-403LT is 1007 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.
