  • Page 7: Description & Operation

    Description & Operation Filter Assembly General Description (Figure 1) The B SERIES self-cleaning filter enables high quality filtration from grades of 50-400 micron from various types of water sources such as sewage, reservoirs, rivers, lakes, and wells. The B SERIES filter contains the following parts: 1.
  • Page 8 SERIES Filter Operation General Description (Figure 1) Water enters the filter through the “Inlet” (1). The water then reaches the fine screen (2), which purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen. As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine Screen (2) and its external section.
