The USGF is a leader in severe wind and severe grease applications.
The USGF is designed for high grease restaurant applications
exhausting grease laden air. The USGF has been subjected to
Miami-Dade test protocols TAS-201/202/203 for wind pressure and
missile impact. After extensive testing exceeding all standards the
USGF was still in operating condition. The USGF is UL / cUL listed for
restaurant exhaust with continuous operation at 400ºF. Constructed
entirely of steel, the USGF stands up to high levels of grease and
consistent cleaning. The non-stick Teflon coated wheel and clean out port allow
for easy cleaning of the fan and it comes standard with all the pieces required
to meet NFPA 96. The USGF has been specifically designed for extreme grease,
high wind and extreme weather applications. A fully welded all steel windband and
high strength steel curb cap with structural bracing on the interior provide the added
strength required to withstand winds of up to 150 mph. The USGF comes standard
