Problem Possible Solution
Blast flow surges. 1. Air pressure too low. Increase air pressure.
2. Too much media. Adjust media valve.
Excessive media consumption. 1. Media valve open to far. Close slightly.
2. Air pressure too low. Increase air pressure.
Clogging and plugging of blast flow. 1. Excessive debris in media. Purge and filter.
2. Media size too large. Use smaller grit size.
3. Nozzle plugging. Use larger nozzle.
4. Nozzle plugging. Adjust media valve.
5. Wet media. Dry media. Drain water from water trap.
