Rotary airlock for uniform and continuous discharge of material from hoppers and dosing into transport or production systems. Available in diameters from 120 mm to 300 mm.
Precision-machined rotor of wear-resistant steel ensures high efficiency even under large pressure differentials in the pneumatic system
The airlock is built with very tight clearances between rotor and stator, making it highly efficient even at greater pressure differentials in the system.
Both housing and rotor are made of wear-resistant steel — ideal for abrasive materials such as sawdust, granules, flour and powders.
With an integrated frequency drive, the gear-motor speed — and thus the dosing capacity — is easily regulated without mechanical interventions.
Available in diameters from 120 mm to 300 mm — choose the optimal size according to your line capacity and hopper or cyclone dimensions.
Standardly installed beneath cyclones in pneumatic conveying systems, ensuring hermetic material discharge without air leakage.
Uniform and continuous dosing into the transport or production system ensures stable flow and prevents blockages in the line.
Material (granules, dust, sawdust) falls by gravity from the hopper or cyclone onto the airlock inlet. The rotor continuously rotates and receives material in the pockets between vanes.
The gear motor drives the rotor at a set speed. Material trapped between the rotor vanes and housing is conveyed from inlet to outlet — with minimal air passage.
At the outlet the rotor discharges material uniformly into the transport or production system. The frequency drive allows precise real-time capacity adjustment to match line requirements.
Rotary airlocks are manufactured to order according to specific system requirements. Feeder capacity depends on rotor diameter and motor-reducer speed. For accurate sizing and capacity selection, contact us with your material data and desired flow rate.
The frequency drive allows infinitely adjustable capacity from minimum to maximum — without stopping the line or mechanical intervention.
The tight clearance between rotor and housing prevents air leakage between pressure zones — critical in pneumatic conveying systems.
Rotor and housing of wear-resistant steel withstand prolonged contact with abrasive materials with minimal wear and infrequent service intervals.
Standard connections and compact design allow installation beneath existing cyclones, filters or hoppers without special civil works.
Diameters from 120 to 300 mm cover all capacities — from small laboratory lines to large industrial plants with high material throughput.
Simple construction without complex mechanisms means high reliability, fewer breakdowns and lower maintenance costs over the full equipment lifetime.
