6.5 cu ft Portable Pneumatic Sandblast Pot – Pressure Release System with MPV/Combination Valves, 1-1/2″ Piping & Big Gun Moisture Separator

Part Number: 888-0531-12914PB
Weight: 516.02 lbs
Warranty: 5-Year Limited / 10-Year Vessel Warranty

Overview

The 6.5 cu ft Portable Pneumatic Sandblast Pot – Big Gun System delivers extreme air and abrasive flow capacity for the most demanding industrial blasting operations.
Equipped with a 1-1/2″ full-flow piping system and Big Gun Moisture Separator, it provides zero-pressure-drop performance that maximizes productivity when using large #7 and #8 blast nozzles.

The Pressure Release System ensures smooth blowdown after each blast cycle, while the MPV/Combination Valve setup guarantees simple control, low maintenance, and reliable field performance.

This model is ideal for shipyards, structural steel, bridge restoration, and large-scale industrial surface preparation.
