USING PORTABLE AIR (85 - 500 HP / 64 - 373 KW)
Portable air compressors are mainly used for shop tools, not dry ice blasting units; therefore, they
are not able to cool or remove air moisture.
An after cooler and moisture trap/filter MUST be used. An after cooler with a 15 °F (-9 °C) approach
is required to reduce the discharge air temperature 180 °F (82 °C) to within 15 °F (-9 °C) of ambient
air temperature.
If an air cooler is not used:

Incoming air moisture will rapidly cool and freeze at the Aero V feeder.

Ice will accumulate in the feeder, distorting the air flow and seal.

Ice will break off inside the hose and lodge in the nozzle, causing a jam.

Ice may exit the nozzle and damage the target surface.
If blasting continuously, use an air dryer to further reduce the air moisture (dew point). Desiccant
dryers produce a dew point of -40 °F (-40 °C), resulting in a dew point low enough for continuous
blasting.
To verify the compressor is of adequate size for the Aero V, the air compressor needs to produce an
air volume 10% greater than the Aero V's maximum permissible air volume. To determine
adequate air volume, watch the pressure gauge while blasting.
 If the gauge drops slowly, the compressor is insufficient.

If the gauge drops quickly, there is a restriction or the pipe is too small.

If the gauge stays steady, then the compressor and piping are adequate.
To maintain adequate pressure, the hose size from the compressor to the Aero V needs to be 1" (25
mm) in diameter.
