Free fall rotary airlock
with self-cleaning rotor

Airlock EDF
High reliability rotary airlock destined for sticky products that flows badly, these products can block partially or totally the rotor’s pockets reducing dramatically its geometrical capacity. 100 % effectivity. Equiped with 2 drived shafts (main rotor and scraper rotor). Taylor made designs. Inlet/outlet flanges square or rectangular. Used for dosage and pneumatic conveying of granular/powdered products. External bearings.
  • Frequency variation integrated in the electrical motor.
  • Thermal sensors and forced ventilation.
  • Mechanical variable speed drives.
  • Air inlets (Pneumatic conveying).
  • Connection for pneumatic conveying pipe.
  • Inlet deflector (for granular products).
  • Spin sensor.
