OPTIONS AND ACCESSORIES XRED AND XREB
Roof Curbs – Prefabricated
roof curbs reduce installation
time and costs by ensuring
compatibility between the fan,
the curb and roof opening.
A wide variety of roof curbs
are available, including flanged,
pitched and sound absorbing.
Hinged Curb Cap with Cables (Field Installed) –
Mounted to the curb cap, allows the entire fan to tilt
away from curb for access to wheel and ductwork.
Includes restraint cables. Not available for high wind.
Hinged Base (Factory Mounted)
Allows for easy maintenance.
Hinge and restraining cables are
factory mounted to a subbase
attached directly to curb without
additional height added. Not
available for high wind.
Curb Seal – Foam seal between fan and curb to
ensure proper sealing when attached to a curb.
Curb Extensions – Extensions
raise the fan discharge above
the roofline and provide an
accessible mounting location
for dampers. Insect screen
bases, constructed with a
removable fine mesh, are recommended for
applications where insect entry must be prevented.
High Wind and Severe
Duty Roof Curbs
–
Provided as optional with models
XRED and XREB. The severe-
duty roof curb models can ship
separately to allow for final
finishing of the roof prior to
the fan arrival and installation.
• Model GPF – This roof curb is specifically designed
for high wind applications used on fan models XRED
and XREB. Standard height is 12 inches (305 mm),
fully welded straight sides with a 5-inch flashing
flange. GPF is available up to 24 inches (460 mm) in
height to meet greater height requirements.
• Model GPFHL – for heavy load applications. Its
construction is intended to support compression
loads exceeding 1,000 lbs (454 kg). GPFHL is
mounted directly to the roof deck structure, and
the roofing material is brought to the vertical
surface and sealed to the flashing flange. Additional
standard construction features include 14
gauge galvanized steel and internal vertical
support members.
• Model GPFHD – for supporting heavy load
equipment in severe-duty, high wind and seismic
applications. The double-thick flashing flange
provides an extremely durable surface to secure
the curb to the building structure. The roofing
material is brought to the vertical surface and
sealed to the flashing flange. Additional standard
construction features include 12 gauge galvanized
steel and internal vertical support members.
