  If your Cold Jet Industrial Equipment blasts air but not dry ice, first ensure that the switch on the applicator is set to Air+Dry Ice (II) mode. Also, check if the trough door is open and close it. If you are using extended lengths of blast hose, verify that your feed rate and compressed air supply is sufficient to compensate. Finally, dry ice clogging the feeder chute can also cause this issue; in this case, follow the Unclog the Dry Ice Chute procedure.

Why Cold Jet Cleaning Equipment won't blast?

  Tracey RuizAug 20, 2025
  Your Cold Jet Cleaning Equipment may not blast due to several reasons. The air filter might be clogged, in which case you should remove the back cover and replace the filter element. Also, ensure that you pull the disable blast button out and flip the switch to deactivate safety. A clogged nozzle can also prevent blasting; try blasting with air only to unclog it.

  If your Cold Jet Cleaning Equipment blasts air but not shaved dry ice, try pushing the plate to the back of the trough and reinserting the dry ice block. Another possible solution is to open the Chute Access Port and blast with compressed air to break any clog.
