Plastic Grit #40110
Primarily used to strip aluminum and fiberglass. Great for stripping paint, light oxidation and surface
rust. Recommended for use in blast cabinets because it creates very little dust. Works quickly, last a
long time and increases visibility within the cabinet. (10 Lb. container)
Walnut Shells #40112
Walnut shells are recommended for use on “soft” surfaces such as aluminum, glass, wood, and
other areas where no pitting is desired. Leaves a smooth, dull finish. (10 Lb. container)
TROUBLESHOOTING TIPS
PROBLEM/CAUSE POSSIBLE SOLUTION
Surging of blast flow:
Air pressure too low Check pressure gauge on compressor
Too much media
Excessive media consumption:
Media valve open too far Close slightly
Air pressure too low Check pressure gauge on compressor
Clogging and plugging of blast flow:
Debris in media Purge and screen
Media size too large Use smaller grit size
Nozzle plugs Use larger nozzle
Nozzle plugs Adjust media valve 40200
Wet media Dry media, drain water from air
Moisture in abrasive media:
Wet media Change or use dry media
Water in air Drain water from air lines
Water in tank Empty, dry out and refill
Humid weather:
Moderate humidity Keep media as dry as possible
Moderate humidity Use drier or moisture separator
High humidity Avoid that period of use if possible
Overtaxed compressor:
Compressor too small Restrict time used
Nozzle size too large Use smaller size
Too many leaks in plumbing Seal and tighten plumbing
Holes in abrasive hose Replace hose
Air filter on compressor plugged Clean
Lack of air pressure:
Compressor too small Use smaller nozzle
Supply valves not on full position Open valves
Nozzle size too large Use smaller size
Leaks in plumbing Seal and tighten plumbing
