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. A rotary airlock is also important in the pneumatic conveying industry, where the product is regulated into a pressure or vacuum conveying line while minimizing air leakage. With Rotolok there are no double standards, all our standard valves and airlocks are precision machined for close tolerances and minimal eccentricities.
