Place the balloon over the inflating outlet. Slightly roll the neck of
the balloon over the inflating tip. This will insure the gas enters the
center of the balloon and the round shape of the balloon is
maintained during the inflation process. Tap the foot pedal or
press the inflation button. It is important to inflate a test balloon
at each adjustment until the desired size is produced.
Conwin’s Duplicator 2 Inflators feature a raised button on the
cycle switch to enable one-hand inflation. Workers can hold the
balloon over the filling outlet and activate the inflation cycle by
pressing the button with the base of their hand.
Set the Inflation Time
Reference the chart (see right) to determine the appropriate
number of seconds required for the inflation cycle. The digital
display will indicate number of seconds.
Set the Adjustable Regulator
Reference the size setting chart (Fig.1) to set the Duplicator 2 to
the appropriate pressure. The PSI setting on the chart
corresponds to the inlet pressure on the adjustable regulator. To
adjust the pressure, pull the black setting knob up to unlock and
turn it clockwise to increase the pressure and the size of the
balloon. Turn the knob counter-clockwise to decrease the
pressure and reduce the size of the balloon. When the unit is
set to the desired size, press the black knob down to lock it in
place.

The following settings should be used as guidelines for the Duplicator 2. Please note
that size settings will vary based on user preference, balloon color and manufacturer.
To adjust the size of balloon to your individual preference, it is necessary to inflate test
balloons.
PSI SETTINGS refer to the gauge located on the adjustable regulator connected to the
back of the Duplicator 2. The pressure setting controls the speed of inflation.
SECONDS SETTINGS refers to the tenth of a second increment readouts on the
digital display on the face plate of the Duplicator 2.
Important: To insure consistent balloon sizing when using helium or nitrogen,
check the size of the balloons every 1/3 of a cylinder of gas. If necessary, increase
the size of the balloon by either increasing the time setting or the inlet pressure on
the adjustable regulator.
Settings for 60/40 Helium/Air Outlet (optional)
The following settings should be used as guidelines when using the optional 60/40
Helium/Air Outlet with the Duplicator 2. The 60/40 Helium/Air Outlet is recommended
for use with 16” or larger balloons.

FOOT PEDAL
Tap the foot pedal to begin the inflation
cycle. When the system automatically
shuts-off, remove the balloons from
the outlets without allowing any of the
air to escape.

1) Set the Adjustable Regulator on the back of the Duplicator 2 to 80 PSI when
inflating foil balloons.
Foil Balloon Inflation
2) Place the foil balloon over the Foil Outlet. Pinch the neck of the balloon between
thumb and forefinger and press down on the outlet. Support the foil balloon in an
upright position until enough helium has entered the balloon to hold it up. This insures
the neck of the balloon does not fold over and restrict the flow of helium. When the
balloon has reached the proper pressure the Duplicator 2 will automatically shut off the
helium flow.
Close the cylinder valve or shut off the air compressor.
Most air compressors are factory set to automatically cycle on at 90 PSI and
automatically cycle off at 120 PSI. The Duplicator 2 must have a steady supply of
air or gas to produce equal size balloons. For accurate sizing, it is essential to work
within the limits of the cubic foot per minute capacity of the air compressor.
Important Guidelines When Using an Air Compressor
• Compressor must build up tank pressure before inflating balloons.
• The output setting on the air compressor should not exceed 80 PSI. If
the compressor is set higher than 80 PSI, the Duplicator 2 will outperform the
compressor’s storage tank capacity.
Air Compressor Required Specifications
• Primary Moisture Filter
• 20 Gallon Storage Tank
• Cycle Pressure: 90 PSI On - 120 PSI Off
• Compressed Air Availability: 6.5 Cubic Foot/Minute @ 90 PSI
• After each job, blow down the compressor to remove water collected
in the tank during compression. The Dual Sizer will require factory rework
and recalibration if moisture enters its system.
• Power surges will affect the accuracy of the Duplicator 2-line voltage must
be steady at 120 volts. Use a power strip with surge protection.
Recommendations For Use With An Air Compressor
Shutting Down the Duplicator 2

Release the pressure from the unit by pressing and holding the Foil Outlet
unitl all of the gas has escaped. Disconnect the supply hose and adjustable
regulator from the back of the unit. Remove regulator from the cylinder.
