3.  Water ice buildup may continue inside the blast hose, to the nozzle.
4.  Water ice may break off inside the hose and lodge in the nozzle, 

causing a jam.

5.  Water ice, may exit the nozzle, and damage   the target surface.

If blasting continuously, an air dryer will 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, the air 
compressor needs to produce an air volume 10% greater than the blast 
system’s maximum required air volume.

To determine adequate air volume, blast while watching the pressure 
gauge.
• If the gauge drops slowly the compressor is insuficient.
• If the gauge drops quickly there is a restriction or the pipe is too small.
•  If the gauge stays steady then the compressor is adequate.

To maintain adequate pressure, the hose size from the compressor to the 
blast system needs to be 1 in (2.5 cm) in diameter.
