 Blowing seals have been introduced to meet the specific needs of the pneumatic conveying industry and are a natural extension to the Rotary Airlock, both being used to regulate the flow of dry powder, dust or granular product, while maintaining an airlock. However, the Blowing Seal has distinct advantages for the specialist as it introduces high pressure conveying air through the valve body and rotor pocket ensuring - HIGH EFFICIENCY THROUGHPUT WITH LOW EFFECTIVE PRESSURE DROP. This is achieved by the fact that more blades are in contact for longer periods with the valve body resulting in less air leakage - and by blowing through the rotor each rotor pocket is efficiently emptied. The Rotolok range of seals are robustly constructed with an emphasis on close tolerances and minimal eccentricities, making the unit suitable for the majority of pneumatic conveying applications.
