Fabricated Steel Adjustable Louver
Drainable Blade
Application and Design
FAD-602 is fabricated adjustable louver designed to protect
air intake and exhaust openings in building exterior walls that
requires 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 FAD-602 is an extremely efficient louver
with AMCA LICENSED PERFORMANCE DATA enabling
designers to select and apply with confidence.

Free Air Velocity
Model FAD-602 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.
The beginning point of water penetration for Model FAD-602 is
*
980 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.
