Features & Benefits:

  • Trough-style openings can be designed to fit dust collectors, hoppers, bins, silos and screw conveyors.
  • Higher capacity with a smaller overall height for tight space engineered solutions.
  • Tighter clearances enable NFPA compliance despite larger capacity outputs (since NFPA clearances can be challenging in larger airlocks).
  • With independent drives, issues or a breakdown in one compartment can be contained and allow other compartments to continue operating.
  • Common parts in a unique housing mean no special maintenance requirements. Spare parts are readily available (whereas spares for larger airlocks can have a longer lead time).
  • Separate airlock compartments allow for intermittent feeds — two, three or four rotors can run simultaneously or independently for multi-line feeds.
  • More compact design than other valves of its kind, which reduces stack-up in silos and dust collectors.
  • Direct drives in each compartment allow for independent operation.


  • Use to break up large pneumatic conveying systems into smaller, more manageable systems.
  • Can be equipped with one elongated blow-through adapter to feed one system or multiple blow-through adapters for different line feeds.
  • Equip with one large pressure blower package or several smaller ones for multiple systems.
