PPB-346 – Portable Sandblaster – 3.5 cu ft (300 lb.)

IST Portable Pressure Blaster PPB 346 is robust and durable sandblasting equipment designed for outdoor applications. 3.5 cubic feet tank capacity steady blasting autonomy and great mobility. Concave shape makes it easy to hold abrasive media and fill the vessel.

IST sanding pot with continuous-pressure system is ideal for frequent on/off operations. Sub-slab depressurization system extends blasting autonomy by filling tank while machine is in standby. Abrasive metering valve provides precise and controlled flow of abrasive.
