Rotolok introduced a low cost solution to dust collector rotary airlock needs. The Dust Collector Rotary Airlock is a lighter duty option for standard dust collection applications.

Constructed with a robust cast iron body and cast iron end covers. Bearings are inboard and shafts are sealed with lip seals. All valves are direct driven with a right angle gearbox and motor.

These valves have been engineered and designed solely as a low cost alternative for applications with pressure differentials of 3 psi or less. Available in sizes from 6″ to 12″ with round and square inlet.

The general market place covers Cyclones, Bag Houses and Gravity Feed applications with pressures around +/- 3 psi
