Heavy Duty Rotary Airlock


The prime function of a rotary airlock is to regulate the flow from one chamber to another while maintaining a good airlock condition. 

The product is mainly in dry powder or granular form. In the dust filtration field, a good airlock is essential on cyclone and bag filter applications in order that the manufacturers quoted high dust collection efficiencies can be maintained. 

Airlocks are also important in the pneumatic conveying industry, where product is regulated into a pressure or vacuum conveying line while minimising air leakage. 

With  there are no double standards, all our standard rotary valves and airlocks are precision machined for close tolerances and minimal eccentricities. Pressure is 0.2Mpa and temperatures to 380℃ are considered the norm and extreme pressures and temperatures can be accommodated with special designs. If your application requires such considerations contact our Engineering team.

Our standard Rotary Airlocks are available with circular or square inlets from 3" up to 20".

Heavy Duty Series Rotary Airlock Valve Features and Benefits


Speed’s Heavy Duty Rotary Airlocks are manufactured in accordance with NFPA 69 Standards for use as deflagration isolation by flame quenching and material blocking.

 All valves are manufactured in either Cast Iron or Stainless Steel from 6” to 24” diameter.  Airlocks come with 6-12 vane fabricated steel rotors with close tolerance to the housing bore and end covers with at least 2 vanes on each side of the valve housing in position of minimum clearance at all times.

 We offer special motors and switches as needed for the hazardous area environment.
