Adjustable Louver
Drainable Blade
Application and Design
EADC-601 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.

) Water Penetration (Standard Air - �075 lb/ft3)
Free Air Velocity
Model EADC-601 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-601 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.

EADC-601INSTALLATION DETAILS
Maximum Size and Installation Information
Maximum single section size for model EADC-601 is 60 in� W x 96 in� H� (without seals)� Larger openings require field assembly
of multiple louver panels to make up the overall opening size� Individual louver panels are designed to withstand a 25 PSF windload (please consult Greenheck if the louvers must withstand higher wind-loads)� Structural reinforcing members may be required
to adequately support and install multiple louver panels within a large opening� Structural reinforcing members along with any
associated installation hardware is not provided by Greenheck unless indicated otherwise by Greenheck� Additional information on
louver installation may be found in AMCA Publication #501, Louver Application Manual�
