Using a portable diesel air compressor, that emits hot and humid air, can affect the quality of your dry ice and hinder the efficiency of your blasting setup.
When compressed air with moisture is introduced to dry ice, small water-ice particles begin to form. This then causes dry ice bridging, where dry ice sticks to itself, and potential clogging in the blast stream. Lastly, since water-ice is more dense than dry ice, it could cause potential damage to the surface you are blasting.
The Cold Jet After Cooler is specifically designed to cool the air and eliminate moisture, resulting in enhanced dry ice blasting performance.
