ROTARY AIRLOCK EDF
Free fall rotary airlock
with self-cleaning rotor
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.
Options:
- 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.
