Description :

Blow-Thru rotary airlock valves are ideal for the Pneumatic Conveying of free-flowing material in food, grain, chemical, milling, baking, plastics and pharmaceutical applications.

The Blow-thru Rotary Airlocks are tailored to address the unique requirements of the pneumatic conveying sector, serving as a logical extension of the traditional Rotary Airlock. These products are essential for controlling the flow of dry powder, dust, or granular materials while effectively maintaining an airlock within pneumatic conveying systems.

The "fanbao" Blow-Thru Airlock is engineered for easy installation in low headroom settings and for retrofitting existing rotary valves. In line with all "fanbao" Rotary Airlock Valves, the blow-through design showcases an innovative, larger vane pocket configuration. These expanded rotary vane pockets can accommodate up to 50% more volume, allowing the rotor to operate at lower speeds compared to rotary airlocks from other manufacturers. This not only boosts efficiency but also prolongs equipment lifespan.

The enhanced design minimizes air leakage, extends the valve's longevity, reduces maintenance requirements, and offers a higher return on investment. More blades come into contact with the valve body for extended periods, decreasing air leakage. Furthermore, the blowing through of each rotor pocket ensures efficient emptying.

The "fanbao" range of blow-thru airlocks boasts robust construction, emphasizing tight tolerances and minimal eccentricities, rendering them suitable for a wide array of pneumatic conveying applications. Available in sizes ranging from 3" to 20", these airlocks are specifically crafted for discharging into pneumatic conveying lines, making them ideal for free-flowing materials that benefit from assistance in clearing the rotor vane pockets.

such as a precision casting, CNC machining, compact design and universal mounting flanges allow for a versatile material handling rotary airlock valve product that can fit virtually every existing bolt hole pattern and replace any existing rotary valve.
