Greenheck EAH-690 Installation Manual

Adjustable Louver

J Blade

Application and Design

EAH-690 is an adjustable louver designed to protect air intake and exhaust openings in building exterior walls that require tight air shut off. Design incorporates a drainable head member and adjustable J style blades with a choice of full open blade angles. Blades can either be specified with blades rotating from 0º to 90º or 0º to 45º. The EAH-690 is an AMCA CERTIFIED LOUVER enabling designers to select and apply with confidence.

Free Air Velocity

Model EAH-690 resistance to airflow (pressure drop) varies depending on louver application (air intake or air exhaust) and blade position (either 45º or 90º blade angle). Free area velocities (shown) are higher than average velocity through the overall louver size. See louver selection information.

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 EAH-690 with blade angle at 45º is

The beginning point of water

1069 fpm free area velocity (blade angle at 90º is 618 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.
