The Greenheck models LBP / LDP are louvered penthouse
powered roof exhaust fans. The LBP / LDP are designed
specifically for general clean air exhaust on life safety and
critical facilities. The backward inclined centrifugal wheel is
enclosed in the SDLE (severe duty louvered enclosure) which
is constructed completely of Miami-Dade Approved louvers
model ESD-603 and passes all Miami-Dade and Florida
Building Code requirements (TAS-201/202/203). The louvered
enclosure is designed to meet all static, cyclic and missile impact requirements for high
wind and hurricane zones. The structural steel interior, extruded aluminum blades and high
strength frame provide the added strength required to withstand design pressures of up to
140 psf. It ships mounted to a standard 24 inch tall SD (Severe Duty) 12 gauge steel curb
and tie downs to the roof are not required.
