The Mod-U-Blast® “P Series” Pressure Dry Blast Cabinets were engineered for maximum production (3 to 4 times faster than standard suction blasting - “S Series”). Mod-U-Blast Pressure Cabinets are equipped with a Pneumatic Valve for optimum safety and blast media flow, direction, and velocity (foot pedal operated). Pressure systems give the control needed to clean at gentle pressures (10 to 20 PSI) or aggressive cleaning as high as 110 PSI.
