Overview

The Portable 6.5 cu ft E-Series Pneumatic Blast Pot – Pressure Hold System is a heavy-duty abrasive blasting solution designed for contractors demanding efficiency, control, and reliability.
The Pressure Hold System maintains pressure between blasting cycles, reducing air and abrasive waste while delivering faster restarts and smoother operation.

Equipped with the Automatic Pinch Valve and X-TREME DUTY™ Metering Tube, this model provides superior wear resistance and precise media flow.
The 1-1/4″ galvanized piping and built-in heavy-duty moisture separator ensure corrosion resistance and dry air delivery for consistent blasting performance across industrial environments.

⚙️ Note: Not for use with steel grit (pneumatic control handle can jam). For steel abrasive applications, use an electric control version.
