Overview

The Pirate Brand® 6.5 cu ft Short-Cycle Stationary Pneumatic Blast Pot is purpose-built for professional abrasive blasting applications requiring fast on-off cycling and consistent pressure retention.
This model features the Short-Cycle System Saver, engineered to prevent overfilling and pop-up seal damage commonly seen during frequent short-duration blasting.

Unlike standard pressure-release blasters, the short-cycle system remains pressurized between cycles, using a remote palm-button blow-down to safely depressurize and refill the vessel as needed. The result is smoother operation, reduced wear, and higher production efficiency.

Short-Cycle System Advantage

Standard SPR blasters depressurize automatically when the control handle is released – ideal for long-duration blasting, but prone to overfill during quick on-off use. The Short-Cycle System overcomes this limitation by:

• Keeping the blast pot pressurized between short cycles.

• Using a palm-button blow-down control to safely depressurize and refill on demand.

• Preventing abrasive burping and seal damage, extending valve and pop-up life.

• Maintaining consistent pressure for faster restarts and smoother blasting.

Perfect for blast rooms, high-frequency production environments, and maintenance operations requiring reliability and control.

Key Features & Benefits

• Short-Cycle Pressure Release System – Remains pressurized during idle periods; depressurizes when the palm-button is engaged.

• APV II Metering Valve with Tungsten Carbide Sleeve – Quadruple-seal plunger design resists wear and solves carry-over and jamming issues in low-pressure or steel-media blasting.

• Combination Valve Design – Dual-action system stops blasting and relieves pressure immediately when activated.

• Big Gun Full Flow System – Provides a zero-pressure-drop path for air and abrasive, maximizing nozzle performance.

• 1-1/2″ Galvanized Piping – Corrosion-resistant and heavy-duty construction for industrial longevity.

• Big Gun Moisture Separator – Ensures clean, dry air supply for consistent abrasive flow.

• Union End Ball Valve – Allows shut-off and service without emptying the vessel.

• 15′ Blow-Down Hose Assembly – Remote-mounted for operator convenience.

• 9″ Adjustable Spider – Supports multiple media sizes and prevents sealing issues in hopper-fed configurations.

• Skirted Pop-Up Gasket – Self-sealing design eliminates abrasive leakage and burping.

• Full Load Lifting Eyes – Facilitate safe handling and positioning of the unit.
