Dust collection systems require the proper airflow to operate correctly. Without the correct air flow, dust will not be removed from collection points and the collection equipment (baghouse, cartridge collectors, cyclones, etc.) will not operate with maximum efficiency. However, if too much air is being pulled through the system, a variety of issues might ensue, such as product being lost, removal efficiency lowered, utility usage increased.

Five Major Air Leakage Issues That Cause Problems to Your Dust Collection System
When selecting the airlock for your dust collector, it is important to think about air leakage. A little air leakage through the airlock isn’t a usually a big deal with many baghouse applications, but air leakage can cause major issues with some applications. So it is important that you identify if your system will have issues with air leakage and then select the proper airlock valve.
Reduce Air Leakage with the Aerodyne Double Dump Valve
When your dust collectors are having issues, one of the first places to look is the airlock valve. Often times, dust is hygroscopic and when outside air leaks into the system, humidity follows. This can cause the dust to absorb the humidity and become sticky or harden like cement. This can lead to plugged filters, hoppers and damage to rotary valves. While rotary valves are the industry standard airlock, they constantly allow air leakage. A low leakage valve is required. Double dump valves however are very low leakage, since there is no direct connection to the outside atmosphere. The valve always isolates the conditions above it from the conditions below it. This minimizes air leakage, thereby minimizing humidity from affecting the dust.
