Rotary Airlocks - Rotolok

Rotary airlocks, also known as rotary valves or feeders, control the flow of bulk materials while maintaining an effective air seal in pneumatic conveying systems. Installed beneath hoppers, bins, cyclones, and dust collectors, they ensure consistent material discharge while minimizing air leakage and preserving system efficiency. Available in multiple configurations, including round flange, square flange, drop-through, and blow-through designs, rotary airlocks are suitable for handling powders, granules, and pellets across food, pharmaceutical, plastics, chemical, and industrial applications. Durable construction and precision engineering deliver reliable, long-term performance in demanding environments.
