Combination Louver/Damper
Drainable Blade
Application and Design
ECD-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 blades with exposed blade
linkage. 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 ECD-601 is an extremely efficient
louver with AMCA LICENSED PERFORMANCE DATA enabling
designers to select and apply with confidence.

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 ECD-601 is 1035 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.

ECD-601INSTALLATION DETAILS
Maximum Size and Installation Information
The maximum single section size for the ECD-601 is 120 in. W x 84 in. H or 84 in. W x 120 in. H (70 sq. ft). 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.
