6.5 cu ft Stationary Pneumatic Blast Pot – Short-Cycle Pressure Release System with APV II (Tungsten Carbide Sleeve & Combination Valve), 1-1/2″ Piping with Big Gun Moisture Separator

Part Number: 888-0431-33954PB-E
Pressure Rating: 150 PSI (10.3 BAR)
Capacity: 6.5 cu ft (185 Liters)

Overview

The Pirate Brand® 6.5 cu ft Short-Cycle Stationary Pneumatic Blast Pot is engineered to deliver smooth, efficient, and reliable blasting for short-duration applications.
Equipped with a Short-Cycle Pressure Release System, APV II (Tungsten Carbide Sleeve), and Combination Valve, it retains the fast refilling advantages of a pressure release system while preventing overfilling and sealing issues common in rapid on/off blasting cycles.

Designed for continuous industrial use, this model maintains pressure between short blasts, ensuring faster restarts, reduced wear, and improved productivity in high-frequency operations.

Short-Cycle System Advantage

The Short-Cycle System Saver is purpose-built for operators blasting in intervals of under 10 minutes.
Standard pressure release (SPR) blast pots automatically refill when depressurized, which can lead to abrasive overfill and pop-up seal damage during frequent cycling. The Short-Cycle System eliminates this issue by keeping the pot pressurized between cycles and featuring a remote blow-down button for quick depressurization and refilling when needed.

This ensures reliable sealing, reduced downtime, and extended component life — perfect for blast rooms, maintenance facilities, and high-cycle production environments.

Key Features & Benefits

• Short-Cycle Pressure Release System – Maintains pressurization between cycles; blow-down initiated by remote palm button.

• Low-Maintenance Design – Simple, durable pneumatic system for easy in-field service.

• Big Gun Full Flow System – Delivers unrestricted airflow and abrasive flow, maximizing performance and minimizing pressure loss.

• APV II (Automatic Plunger Valve II) – Premium metering valve with solid tungsten carbide sleeve for superior wear resistance and precise control.

• Combination Valve Design – Dual-function operation automatically stops blasting and relieves pressure when activated.

• Big Gun Moisture Separator – Removes moisture and debris from the air supply to prevent clogging and abrasive contamination.

• 1-1/2″ Galvanized Piping – Corrosion-resistant for long-term reliability in harsh environments.

• Union End Ball Valve – Enables maintenance without dumping the vessel.

• 9″ Adjustable Spider Assembly – Adapts to different abrasive types and ensures consistent pop-up sealing.

• Skirted Pop-Up Gasket – Enhances sealing reliability and prevents abrasive “burping.”

• Full Load Lifting Eyes – Safe handling and transport during setup or maintenance.

Specifications

Performance Notes
