LOUVER TYPE K8504 PRODUCT DESCRIPTION & DETAILS
AIROLITE LOUVER TYPE K8504
is a combination louver that incorporates drainable stationary and adjustable
blades in a single 4-inch (101.6 mm) deep frame. Combination louvers offer constant exterior appearance yet afford optimum control of intake and exhaust airflows through operation of the adjustable blade. When open, gutters incorporated in
the stationary blades and jamb frames provide excellent resistance to water penetration and high volume intake and exhaust
ventilation. When closed, dual durometer vinyl blade-edge gaskets effectively minimize air leakage and water penetration.
The continuous integral hinge construction enables this louver to be made in single sections up to 120-inches wide to achieve
maximum mullion spacing. The adjustable blade may be controlled with manually operated hand-cranks, pull-chains, fusible-link mechanisms, electric motors or pneumatic actuators. Louver Type K8504 is an extremely efficient combination
louver with AMCA Licensed air performance and water penetration ratings that enable designers to select and specify this
product with confidence. Please contact your local Airolite representative or the factory for assistance with the layout and
design of operator and support systems when required.

Free Air Velocity
Louver Type K8504 resistance to airflow is
shown with louver blades fully open. Resistance
(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.
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 point of zero
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 Louver
Type K8504 is 805 fpm free area velocity. These performance ratings
do not guarantee a louver to be weatherproof or stormproof and should
be used in combination with other factors including good engineering
judgement in selecting louvers.
