General Information &
Specifications
The Compressed Air Cooler from Condux International cools compressed air from a
maximum temperature of 250°F (121°C), to within 5°F (3°C) of the ambient
temperature (Figure 1). The compressed air cooler is intended for use with the
Condux Fiber Optic Cable Blower to help prevent heat damage to the fiber optic
cable during installation (Figure 2).
A. SPECIFICATIONS
1. Minimum ambient operating temperature: 41°F (5°C).
2. Maximum ambient operating temperature: 140°F (60°C).
3. Minimum inlet operating temperature: 41°F (5°C).
4. Maximum inlet operating temperature: 250°F (121°C).
5. Maximum operating pressure: 135 psi (9.3 bar).
6. Always use in a well lit area with a light intensity of at least 200 lux.
7. Machine weight: 136 lbs (61.7 kg).
8. Maximum noise reading: 90.7 dbA.
9. Maximum flowrate: 400 SCFM (11326 SLM).
10. Only portable air compressors with its own isolation and dump valve must
be used and must be locked in the closed position when changing hoses.
The relief valve on the portable air compressor should not be rated over
the maximum operating pressure of the air cooler.
Set-up and Operation
A. PLACE AIR COOLER
Place air cooler on flat and level surfaces on a slope less than 10 degrees, which are
free of heavy dust and debris to avoid flying debris emitted from the cooling fan.
Never place the air cooler below gantries, power lines or walkways where there might
be a risk of falling objects.
B. NEVER STEP ON AIR COOLER
The air cooler must not be used as a step and hoses which are connected to the
cooler must not be located where personnel will be at a risk of tripping over them.

C. CHECK FAN
Check fan blade before set-up to make sure it is free of obstruction (Figure 3). Blade
should rotate counterclockwise when Compressed Air Cooler is running.
!CAUTION: Never lean over or look down into the cooling fan when
operating the air cooler.
D. ADJUST FAN MOTOR
The air cooler is equipped with an OSHA approved lockout valve. In the closed
position, the valve blocks air to the pneumatic fan motor. A padlock can be placed
on lockout valve to prevent unauthorized usage. Push lockout slide down to unlock
(Figure 4).
E. ADD LUBRICANT FOR FAN MOTOR
Remove lubricator shatter guard by pushing it up and turning clockwise. Remove
reservoir. Fill lubricator reservoir with SAE 10 weight detergent oil. Replace reservoir
and shatter guard (Figure 5).
F. CONNECT HOSES
Secure compressor hose to inlet pipe on Compressed Air Cooler. Secure Fiber Optic
Cable Blower hose to outlet pipe on Compressed Air Cooler (Figure 6).
!WARNING: System under pressure. Use safety clips on all
pneumatic hose connections. Always wear personal protective
equipment.

G. OPERATE
Start air compressor.
H. ADJUST FAN MOTOR PRESSURE
NOTE: Fan motor, lubricator and pressure are all factory pre-set, but do require
monitoring at all times.
Turn clockwise to increase pressure or counterclockwise to decrease pressure.
Fan motor pressure should be 35 psi (2.4 bar). When reducing pressure, first set
pressure below desired level and slowly increase pressure until desired level is
achieved. Once proper pressure level is set, turn locknut down to set pressure
(Figure 7).
!CAUTION: Operate pneumatic fan motor at 35 psi (2.4 bar).
Operating Compressed Air Cooler above 35 psi (2.4 bar) can cause
damage to unit.
I. ADJUST FAN MOTOR LUBRICATOR
Lubricate fan motor at approximately one drop SAE 10 weight detergent oil per
minute. Turn oil adjustment knob (the small one) counterclockwise to increase and
clockwise to decrease oil delivery. Monitor unit for excess oil drainage or slow
performance. Adjust oil delivery accordingly (Figure 8).
!IMPORTANT: When adjusting the lubricator, the valve only has to be turned
1/8 of a turn, it is very, very sensitive. If it is turned farther, oil will blow out of
the top of the fan. Operator wants only 1 drop of oil per minute.
J. MONITOR
Continue to monitor air pressure and oil
delivery to pneumatic motor (Figure 9).
!WARNING: Inlet pipe is HOT.
Touching inlet pipe could result in
serious personal injury.
!WARNING: Heat transfer surface
(grill) is HOT. Touching the heat
transfer surface could result in
serious personal injury.

Regular Service
It is necessary to perform the following steps
once per work shift
to ensure the
proper function of the Compressed Air Cooler.
!WARNING: System under pressure. Do not attempt to service air
cooler until air power is disconnected, the system has
depressurized, and all components have cooled.
A. EMPTY FAN MOTOR MOISTURE SEPARATOR
Open drain valve by pushing white slide valve in on fan motor moisture separator.
Allow to drain (Figure 10).
NOTE: Monitor water level of moisture separator regularly and keep levels
below baffle.
B. EMPTY BLOWER MOISTURE SEPARATOR
Loosen blower moisture separator drain valve by turning counterclockwise, allow to
drain (Figure 11).
!IMPORTANT: Monitor and drain moisture separators at least
once per work
shift
to prevent water from freezing inside air cooler or causing corrosion.
Depending on usage and environmental conditions, moisture separators may
need to be drained more often.

Maintenance and Cleaning
Regular maintenance is necessary to keep the compressed air cooler running
properly. It is advised to clean the entire unit thoroughly on a regular basis.
!IMPORTANT: Do not clean with caustic cleaners.
A. INSPECT AND CLEAN UNIT
Inspect unit regularly for loose bolts and connections, rust and corrosion, and a dirty
or clogged heat transfer surface. Tighten loose bolts and connections. Loosen dirt
and dust from heat transfer surface with a brush, then remove with pressurized air.
B. CLEAN FAN
Keep fan shroud, fan, and motor free of dirt and grease to ensure proper function.
C. CHECK FAN MOTOR MOISTURE SEPARATOR FILTER
Remove fan motor moisture separator reservoir by pressing up and turning clockwise.
Check filter element and replace when dirty (Figure 12).
