Greenheck EHM-601 Installation Manual
Hidden Mullion Louver
Dual Drainable Blade
Application and Design
EHM-601 is a weather louver designed to protect air intake and
exhaust openings in building exterior walls. Design incorporates
drain gutters in the head member and horizontal blades to
channel water to the jambs where water is further channeled
through vertical downspouts and out at the sloped sill. The EHM601 is an extremely efficient louver with AMCA LICENSED
PERFORMANCE DATA enabling designers to select and apply
with confidence.

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 EHM-601 is 1065 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.
