Drainable Blade Louvered Penthouse
Application and Design
ESD-635PD is a gravity intake or exhaust louvered penthouse. Model ESD-635PD incorporates high performance horizontal
drainable style blades. Meets the performance requirements 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). This system should be installed in a location where the enclosed area/room inside the penthouse
is designed to drain water penetrating into the area/room, and the area/room will house water resistant/proof equipment,
components and/or supplies. Roof curbs specifically designed for model ESD-635PD may be supplied by Greenheck as an
option. Qualified for installation onto concrete/masonry, steel stud, structural steel or wood substrate. Model ESD-635PD may
also be supplied as an equipment enclosure without hood members.

Performance data shown herein is a result of in-house airflow resistance testing procedures in an AMCA Accredited
Laboratory. The static pressure drops shown at given throat velocities include the pressure drop through the throat of the
product as well as through the louvers themselves. The recommended height shown herein allows for equal to or greater than
effective louver free area to that of the penthouse inside throat area. Increasing the product height will have minimal affect on
the static pressure drop. The static pressure drops shown do not include the effects of bird screen, insect screen or any other
appurtenance.
