EQUIPMENT SUPPORTS AND CURB EXTENSIONS
Models GESS and GESR
These equipment supports are designed for use on both insulated (GESR) and
non-insulated (GESS) flat roof decks. A variety of sizes and widths are available.
Models GESS and GESR are available in welded aluminum or galvanized steel.
Available in heights of 8, 12 and 14 inches and widths of 4, 6 and 8 inches.
Models GPE and GPEX
Both curb extension models mount between the fan and roof curb. Heights range
from 12 up to 24 inches. Models consist of welded aluminum or galvanized steel.
The GPE is designed with an access door to provide easy access to the damper
and damper actuator as well as fulfilling additional height requirements. The GPEX
is also designed to provide additional height requirements without an access door.
Model GESI
This equipment support is designed for use on a flat or single pitched roof.
Standard construction consists of welded galvanized steel with an option for
aluminum in a variety of lengths to match the size of your equipment. Model GESI
has heights ranging from 8 to 18 inches and widths of 4, 6, or 8 inches are available.
Model VCE
The VCE vented curb extension is typically used in kitchen applications, where the
vents allow hot air and gases to escape between the ductwork and the roof curb.
Designed for use with an 8-inch high roof curb and Accurex’s model XRUB, XRUBS
or XRUD fan to provide the required 40-inch minimum discharge height above the
roof (per NFPA 96). Model VCE is available in galvanized steel or aluminum.
Model ISB
Insect screen bases are available for applications where the building must be free
of insects, as in food processing operations. Insect screen bases mount between
the supply fan and the roof curb and provide an additional 6 inches of height. Two
bolted access doors are provided for removal and cleaning of the screen. Model
ISB is constructed of galvanized steel or aluminum with a fine mesh screen made
of aluminum or stainless steel.
Adapters and Reducers
Used to adapt or reduce the standard fan curb cap dimensions to a
non-standard specified curb size, within 10 inches of standard. Adapters
and reducers are most commonly used to match new fans to existing
roof curbs. Construction consists of welded galvanized steel or aluminum.
