Our premier mobile pressure blasting system. The PT-100 has a large capacity, powerful blast system and all the power you need. The unit easily rolls on the large rubber-treaded wheels and with a 10 ft long hose, the user can work without the hassle of constantly moving the unit. Pressure blast systems utilize a pressure vessel or a "pot". Don't settle for any pressure vessel that does not carry an ASME (American Society of Mechanical Engineers) approval. Abrasive media is poured into the pot and then the pot is pressurized. The user then opens a valve and the pressure flows out of the pot carrying the abrasive with it. Pressure pots can be connected to a cabinet or they can be stand alone units like our PT-100 and PT-100-SK. Direct pressure units can reside on a blast cabinet or as with our units roll on heavy duty wheels. Direct pressure units provide sufficient energy to push any type of abrasive, at a lower pressure than siphon fed units.
