Air cannons for resolving bulk material flow issues
Solve bridging and rat-holing issues in bulk material storage with powerful air blasts, ensuring consistent flow and reducing downtime in your production line.

Enhances Material Flow and Prevents Blockages
The GUNJET PG Air Cannons from WAMGROUP are expertly engineered to tackle material flow challenges, ensuring uninterrupted operations across various industries. With an electro-pneumatic or fully pneumatic operation, these cannons inject high-pressure gas bursts up to 6 bar, effectively collapsing bridging and rat-holing in silos and hoppers. Ideal for applications involving fibres, shavings, flakes, and more, they maintain steady flow for end-products, including fish feed pellets, cocoa powder, and wood chips. Their robust design, with galvanized steel and aluminium components, ensures durability for both indoor and outdoor installations. Available in multiple sizes, these cannons integrate seamlessly into existing systems, complete with mounting plates for quick setup. Choose GUNJET PG Air Cannons for reliable material management and enhance your processing line efficiency.
