EXPLOSION PROOF PORTABLE FAN MODELS: CVF-8X220 AND SVF-10X220
TECHNICAL
These fans have been designed for use in hazardous locations in accordance with the ATEX Directive 94/9/EC and the
applicable IECEx criteria. It is the user’s responsibility to determine the suitability of these fans for use in the intended
environment based on tested and approved ratings for the fans:
These fans manufactured by Air Systems International, Inc. conform to the relevant Essential Health and Safety Require-
ments of the European Machinery Directives and evaluated to:
DESCRIPTION OF FAN COMPONENTS
Model CVF-8X220 is comprised of an explosion-proof motor, conductive polyethylene blower housing, metal nger
guards, and external grounding lugs. Model SVF-10X220 contains the same components except the blower housing is
made of steel. The units have beeen tested by Intertek and assigned ATEX and IECEx certication numbers from the
ATEX notied body and IECEx certication body respectively.
The on/off switch is designed and built-in to each motor and a 10 meter power cable is installed with each fan. SPECIAL
CONDITION OF SAFE USE; power cable must be outtted with an explosion-proof plug that is approved for the hazard-
ous location that the fan will be used in. appleton manufatures the explosion-proof plug that complies with international
standards: en 60079-0, -1,7,61241-0,-1.

TECHNICAL INFORMATION, SET-UP, AND CARE
EXPLOSION-PROOF PORTABLE FAN MODELS: CVF-8X220 AND SVF-10X220
Start-Up And Installation
Secure a grounded electrical source that delivers 220vac, 50/60hz, and at a minimum 5 amps. If the blower is
going to be used in a hazardous location, make certain the proper plug is used and the electrical receptacle is
design to handle the plug rated for the hazardous location and in conformance with local electrical codes. Inspect
the blower to ensure all safety guards are in place and that the unit has not been damaged prior to use. Inspec-
tion and set-up should only be done by trained personnel in the proper use of this equipment. Make sure the
blower intake is not located near the exhaust of a gasoline or diesel engine; this will cause the blower to pull in
carbon monoxide and force it into the space that is being ventilated.
OPERATION
The blower is off when the on/off switch is fully depressed and the “power on” occurs when the switch is pulled
outward from the fan housing. These fan motors are equipped with automatic thermal overload switches which
may turn off the blower during operation. Once the fan motor cools, the motor will re-start automatically. If this
condition occurs, disconnect the fan from the electric source and determine the reason for motor overheating.
Check to make sure that: 1) the proper extension cord gauge is used 2) check the blower intake for debris that
may be clogging the air inlet or causing the fan blade to not rotate. Always use conductive anti-static ducting
when working in a hazard area. If using Air Systems’ ducting, attach the installed ground wires to the blower for
added static dissipation. If the Conductive Saddle Vent® device from Air Systems is being used, make sure the
duct is secured to the black Conductive Saddle Vent® properly. The entire ventilation system should be checked
above ground for conductivity prior to starting work; this can be done with an Ohm meter by touching the meter
lead to the farthest end of the duct and the other meter lead to the ground lug (or ground wire) on the blower. A
reading of less than 750K ohms will assure that static charges will move safely to the grounded source.
MAINTENANCE AND WARRANTY
Before each use, inspect the fan for proper nger guards being installed and that no debris is lodged in the blower
intake. Inspect the power cord for no breaks or exposed wire. Dust can accumulate on the inside of the blower
housing and fan blade. These can be blown with an air nozzle to remove excess dust. No other annual mainte-
nance is required. All Air Systems fans and blowers are warranted for one year from the date in purchase. Con-
tact your authorized dealer for any other repair or maintenance questions.

SAFETY PRECAUTIONS
READ AND FOLLOW ALL INSTRUCTIONS BELOW
All ventilation procedures should comply with regulations. Air quality should be tested prior to ventilating a
con ned space. Air quality should be tested continuously during con ned space occupancy to ensure a sta-
ble atmosphere and worker safety as atmospheric conditions can change rapidly. Additional procedures and
recommendations are available from federal, state, and local agencies. DO NOT operate these fan units in a
vertical position or with the  ange or guards removed.
Note: If volatile or explosive vapors are suspected, use Air Systems’ explosion proof in-line fan, Model: SVF-
10X220 or explosion proof contractors fans, Models: CVF-8X220 or CVF-12EX22.
Note: For con ned space ventilation in non-hazardous locations, use Air Systems’ con ned space ventilation
kit, Model SV-CUP. For hazardous locations use ventilation kit, Model SV-CUPCND along with one of the
above explosion proof blowers or fans.
WARNING
Fan and blower models with the “EX” or “X” designation are the
only models approved for use in hazardous locations. These
models are NOT approved for use in mines.

STEP 2)
Place fan in a clean fresh air environment. Note: Inspect fan for damaged or worn parts. Inspect all ducting and couplings
for possible air leaks prior to fan operation.
Note: Air quality of the conned space should be tested prior to ventilation. If air quality of the conned space is unaccept-
able, consult a trained professional.
STEP 3)
Install duct cuff to exhaust ange and tighten cinch strap. Keep bends and kinks in ducting to a minimum to maximize air
ow.
NOTE: The use of conductive ducting is recommended when operating in potentially explosive environments. Assure that
the fan is properly grounded before operating and the ground wire in the conductive ducting is attached to the fan and
Saddle Vent®, if used.
CAUTION
If explosive or volatile vapors are suspected or present, test the fan
for proper grounding using an ohm meter. All static electricity must
be removed from the fan and attached ducting prior to energizing the
fan. Conductive ducting should be tested semi-annually to assure
resistance (ohms) does not exceed 750k. If sufcient resistance is
not achieved, the duct should be removed from service.
STEP 4)
The “ON/OFF” switch is integrated in the motor. Pull the “ON/OFF” switch knob outward to turn the fan “ON”. The unit is
now operational. To turn the fan “OFF,” push the switch knob in toward the fan housing.

PROBLEM POSSIBLE CAUSE SOLUTION
Excessive vibration
Air intake blocked Turn fan off and clear debris from intake.
Possible internal damage
Turn off and inspect fan blades, shaft, and housing
for debris, damage, and loose screws.
Note: Never run fan for extended periods without
installing duct on the exhaust  ange.
Possible external damage Turn fan off and inspect for loose guards,
broken welds, etc.
Circuit breaker trips Voltage output insuf cient Test outlet with volt meter.
Automatic thermal over-
load in motor trips
Extension cord is not of suf cient
gauge
Eliminate extension cord and restart or
obtain extension cord of suf cient gauge
STEP 1)
Explosion-proof models should be tted with an ATEX/IECEx approved explosion-proof plug (Killark P/N ELAP15232) to
meet hazardous locations specications. The plug should not be disconnected or connected in a hazardous environment.
