Heavy-Duty Self-Cleaning Rotary Valve Airlock

Rebuildable | Abrasion-Resistant | Designed to Eliminate Material Build-Up

Precision Machine & Manufacturing introduces the industry’s first rebuildable, abrasion-resistant, self-cleaning rotary valve airlock, purpose-built for handling sticky, fibrous, or compacting materials that typically clog standard airlocks.

Featuring a dual-rotor clean-out system, the synchronized lower rotor actively clears residual buildup from the upper rotor pockets—ensuring uninterrupted material flow, even in the most challenging environments.

Key Features:

  • NFPA-Upgradeable: Configurable to meet NFPA 69 & 85 compliance if/when needed.

  • Self-Cleaning Dual Rotors: Continuous pocket clearing prevents buildup and blockages.

  • Abrasion-Resistant Steel Alloy Construction: Special U.S. sourced, surface-hardened steel alloy, rated at nearly 60 Rockwell, ensures dependability and longevity

  • Rebuildable Design: Field-replaceable wear components for reduced downtime.

  • Consistent Throughput: Eliminates hang-ups, improves system flow.

  • High Efficiency: Maintains feed rates in tough, sticky, or wet material applications.
