Greenheck EAD-401 Installation Manual
Adjustable Louver
Drainable Blade
Application and Design
EAD-401 is an adjustable louver designed to protect air intake and
exhaust openings in building exterior walls that require tight air shut
off. Design incorporates a drainable head member and adjustable
drainable blades to channel water to the jambs which guides
the water through vertical downspouts for escape at the sill. The
EAD-401 is an extremely efficient louver with AMCA LICENSED
PERFORMANCE DATA enabling designers to select and apply
with confidence.

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 EAD-401 is 920 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.
