Greenheck EADC-401 Installation Manual
Adjustable Louver
Drainable Blade
Application and Design
EADC-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 sill conceals the actuator and the adjustable blades are always
motorized.

Free Air Velocity
Model EADC-401 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.
Test size 48 in. x 48 in. Test duration of 15 min.
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 EADC-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.
