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 Air Velocity
Model EACA-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

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.
