The Inner Air Blow Gun

has no pressure adjustment - it is used to sandblast larger
surfaces and elements.
•
Adjust the sandblasting intensity appropriately, depending on the type of object to be
cleaned.
•
For solid, thick-walled objects, the pressure may be near the maximum, which is 8.6 bar (125 psi).
•
For objects with openwork structure, it is recommended to lower the pressure to 5 bar (125 psi).
•
If despite lowering the pressure, the object becomes damaged, select lower pressure value
empirically, as appropriate.
