INTRODUCTION
A Mini Cold Air Gun is a device that converts ltered, 100
psig (6.9 Bar) compressed air into a cold airstream.
The Mini Cold Air Gun consumes 8 SCFM (227 SLPM) of
compressed air and is perfect for a wide range of industrial
spot cooling and dry machining applications.
COMPRESSED AIR SUPPLY
The compressed air supply must be ltered to remove
water and dirt using a 5 micron or smaller lter. Failure
to use a lter may cause clogging (and freezing) of the
compressed air paths inside the Vortec product. Filter
recommendations are given in Table 1.
Filter elements must be changed on a regular basis.
Frequency of change is determined by the condition of
the compressed air supply. Filters should be installed in
the compressed air supply line as close as possible to the
Vortec product.
The appropriate size of compressed air supply line should
be selected to ensure optimal performance of the Vortec
product. Please refer to Table 2 to determine what supply
line size is recommended for your application. Contact
Vortec at 1-800-441-7475 for further assistance.
If water vapor is present in the compressed air supply, a
compressed air dryer may be necessary to prevent ice
formation on the inside of the Vortec product.
INSTALLATION
A Mini Cold Air Gun can be installed by directly plumbing to
the appropriately-sized hard piped compressed air source
that does not exceed 150 psig (10.3 Bar).
OPERATION
Mini Cold Air Guns are designed to create the maximum
amount of refrigeration when operated at 100 psig (6.9
Bar) to 150 psig (10.3 Bar) compressed air inlet pressure.
They will operate at lower pressures, but the amount of
refrigeration will be reduced as well as the compressed
air consumption. At compressed air conditions of 100 psig
(6.9 Bar) pressure and 70°F (21°C) air temperature, the
Mini Cold Air Guns will produce 350 btuh (102 watts) of
cooling by creating a total ow of 4 SCFM (113 SLPM) of
cold air at 10°F (-12°C). Do not restrict the ow of cold air
out of the exible nozzle(s).
MAINTENANCE
The Mini Cold Air Gun has no moving parts (other than the
adjustment knob), and requires only ltered compressed
air for proper operation. The Mini Cold Air Gun can be
disassembled for cleaning, if necessary, as shown above.
If the Gun has been disassembled for cleaning, the Cold
Cap must be reassembled tightly to ensure that the
Generator seats tightly against the body assembly. A loose
Cold Cap will reduce cooling capacity.
TROUBLESHOOTING
Insufficient airow may be caused by the following:
1. Undersized compressed air line size.
2. Compressed air pressure too low.
3. Partial or complete blockage of internal compressed air
path, due to dirt. See Maintenance section for cleaning
instructions; and Compressed Air Supply section for
lter recommendations.
4. Insufficient compressed air volume.
5. Loose cold cap. This may occur if not tightened properly
after disassembled for cleaning.
If trouble persists, please contact Vortec at 1-800-441-
7475.
LIMITED WARRANTY
Vortec compressed air products manufactured by ITW Air
Management will be replaced or repaired if found to be
defective due to manufacture defect within ten years from
the date of invoice.

details and limitations. ITW Air Management makes no
specic warranty merchantability or warrant of tness to a
particular purpose.
1. Do not operate the Mini Cold Air Gun at air pressures
above 150 psig (10.3 Bar).
2. Do not operate the Mini Cold Air Gun at line
temperatures above 110
