Greenheck Fan UL 762 - Manual

Inline grease exhaust fans are excellent alternative for kitchen applications when roof or wall mounted ventilators
are not practical. The TCB with UL 76 grease option is designed to withstand the demands of high temperature
kitchen grease exhaust and high-pressure duct washes.
Continuously welded housing and integral duct flanges
provide air and water tight design.
Bearing cover gasketed and includes a labyrinth shaft seal
to prevent moisture leakage during normal operation and
while cleaning with high pressure solvents.
Continuously welded belt tube keeps the belts and
bearings clean.
Two threaded drain connections are located 90° from the
motor location to allow for removal of grease and moisture.
UL 76 is concerned with fans
designed for removal of smoke and
grease laden vapors with airstream
temperatures up to 300°F.

extraction options. Take advantage of Greenheck’s
expertise in providing a total solution in kitchen
ventilation equipment.
A Tough Package to Beat
Leak Resistant Construction Features
Inline grease exhaust fans should be installed near the end of the duct run to reduce sound at the hood.
Inline fan must be securely bolted to the exhaust duct per NFPA-96 guidelines. Greenheck’s companion flanges
are recommended for ease of installation.
Grease exhaust fans and ductwork must maintain 18 inches (46 cm) minimum clearance to combustible
material. If the ductwork and fan are insulated, the inspection door must be accessible for maintenance.
A minimum of 10 ft. (3.0 m) of clearance must be kept from the fan outlet to adjacent buildings, property lines,
or the closest point of any air intake or operable window at or below the plane of the exhaust termination.
Greenheck recommends that all inline grease applications be reviewed by your local code official to ensure
compliance with NFPA, IMC, and other local codes. •
