It is used to feed the product regularly and without leaking out into pneumatic conveying pipes at the pneumatic conveying systems.

GENERAL DESCRIPTION

The PNA Series Pneumatic Air Lock feeds product regularly into pneumatic conveying pipes without leakage. It is essential for maintaining pressure differential between storage or process equipment and conveying lines handling cereals, oil seeds and by-products.

Every component is engineered for high standard quality in painted or unpainted versions. Safety precautions, accident prevention and environmental legislation receive special attention.


WORKING PRINCIPLE

Rotating vanes or cells isolate sections of the inlet and outlet while transferring product. This allows high-pressure air on one side while material discharges on the other without air loss, preserving system efficiency.


APPLICATION AREAS

  • Pneumatic conveying pickup and discharge points
  • Cyclone and filter product return lines
  • Grain and powder feeding to pressure lines

Rotary air locks maintain the pressure boundary between blowers and receiving equipment while feeding product at a steady rate. Chain coupling and grouped drive installation simplify alignment during plant commissioning and extension projects.


FEATURES & ADVANTAGES

  • Occupies less space
  • Easy erection including drive unit and chain coupling
  • Minimum maintenance
  • High efficiency sealing performance
