Media flow is intermittent or air only flows out of the tip?

Results are taking too long?

Too much media is being released with low pressure?

Material continues to flow after the foot pedal is released?

    • Keep the tanks full with material to decrease the bleed time.

For I/O Units — All handpieces are blasting at once?

  • Make sure to depressurize each tank when you are done using it by switching to “OFF/FILL” before switching to the next tank or leaving the station.
