Model FJ-M Fume Jet Fan
Model FJ-M is a pre-engineered, factory supplied combination of a
centrifugal blower with a discharge stack. Designed to follow ANSI Z9.2
standard for local exhaust systems. Fan offers extended discharge to reduce
and prevent exposure to harmful fumes. Performance capabilities range up
to 17,000 cmh and up to 5.8 in. wg. of static pressure.
FJ-M fans are available in 8 sizes with wheel diameters ranging from 315 -
710 mm. Each fan shall bear a permanently affixed manufacturer's engraved
metal nameplate containing the model number and individual serial number.
General Safety Information
Only qualified personnel should install this fan.
Personnel should have a clear understanding of these
instructions and should be aware of general safety
precautions. Improper installation can result in electric
shock, possible injury due to coming in contact with
moving parts, as well as other potential hazards. Other
considerations may be required if seismic activity
is present. If more information is needed, contact a
licensed professional engineer before moving forward.
1. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the National
Fire Protection Agency (NFPA), where applicable.
2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.
3. Motor must be securely and adequately grounded.
4. Do not spin fan wheel faster than max cataloged fan
RPM. Adjustments to fan speed significantly effects
motor load. If the fan RPM is changed, the motor
current should be checked to make sure it is not
exceeding the motor nameplate amps.
5. Do not allow the power cable to kink or come in
contact with oil, grease, hot surfaces or chemicals.
Replace cord immediately if damaged.
6. Verify that the power source is compatible with the
equipment.
7. Never open access doors to a duct while the fan is
running.
