Greenheck ESS-502D Installation Manual
Miami-Dade Qualified
Sightproof Louver
Application and Design
ESS-502D is an extruded aluminum sightproof louver designed
to protect air intake and exhaust openings in building exteriors
specifically for applications requiring extremely high structural design
loadings. Design characteristics meet the performance criteria
established by the Florida Building Code and Miami-Dade County.
Tested in accordance with and passes TAS 201 (Large Missile
Impact), TAS 202 (Uniform Static Air Pressure) and TAS 203 (Cyclic
Wind Loading). The ESS-502D may be installed in a location where
the space behind the louver is designed to accept water penetration
and houses water resistant/water proof equipment, components or
supplies.

Free Area Velocity
Model ESS-502D resistance to airflow (pressure drop)
varies de12941.1 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
information.
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 ESS-
502D is 1057 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.
