Hazardous Sidewall Propeller Fans
Hazardous sidewall propeller fan line is the ideal choice for
ventilating spaces containing flammable or explosive vapors,
gases, or dusts as defined under Article 500 of the National
Electrical Code (NEC). Direct drive exhaust fans can be
mounted in vertical or horizontal positions.
Performance spans the range between 604 to 6,317 cfm
(1026 to 10,733 m
3
/hr) with static pressures up to .5 in. wg
(125 Pa). Fan sizes range from 12 to 24 inches (305 to 610
mm). Regardless of fan size or performance all Greenheck
sidewall propeller fans are built to perform with the same high
standards of reliability and durability.
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 high winds or seismic
activity are present. If more information is needed,
contact a licensed professional engineer before moving
forward.
WARNING
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power
source can result in fire, shock or serious injury.
CAUTION
When servicing the fan, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.
CAUTION
Precaution should be taken in explosive atmospheres.
AVERTISSEMENT
Pour écarter les risques d’incendie, de choc électrique
ou de blessure grave, veiller à toujours débrancher,
verrouiller et étiqueter la source de courant avant
l’installation ou l’entretien.
ATTENTION
Lors de toute intervention sur la soufflante, le moteur
peut être suffisamment chaud pour provoquer une
douleur voire une blessure. Laisser le moteur refroidir
avant toute maintenance.
ATTENTION
Faire preuve de précaution dans les atmosphères
explosives.
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 propeller 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 propeller 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. Verify that the power source is compatible with the
equipment.
6. Never open access doors to a duct while the fan is
running.
