Combination Louver/Damper
Airfoil Blade
Application and Design
EACA-601 is a combination louver/damper designed to protect air intake
and exhaust openings in building exterior walls that, at times, require tight
air shut off. Design incorporates a drainable head member, drainable
stationary blades and operable airfoil blades. When the operable blades are
open, airflow is permitted through the louver, when the blades are closed,
a tight seal is created to prevent the passage of air. The EACA-601 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 EACA-601 is 1221 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.
EACA-601INSTALLATION DETAILS
Maximum Size and Installation Information
The maximum single section size for the EACA-601 is 60 in. W x 96 in. H. 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 wind-load (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.
