A method of cleaning a complex powder transfer system including providing a powder transfer system having a washing fluid source, a spray device valve in fluid communication with the washing fluid source, a backflush valve in fluid communication with the washing fluid source, a receiving device having an upper chamber, a lower chamber, and a membrane filter disposed between the upper and lower chambers. The method includes opening the backflush valve to initiate a backflush cycle, running the backflush cycle to wash the upper chamber with a fluid, and closing the backflush valve after the backflush cycle completes. The method includes opening the spray device valve to initiate a spray device cycle, running the spray device cycle to wash the lower chamber with fluid, and closing the spray device valve after the spray device cycle completes. The method includes opening a pressure valve to provide PCA to the receiving container.

A secondary filter element for a filter system for filtering a gaseous fluid, in particular for a self-cleaning intake air filter system of a motor, has a filter medium which in the intended operation is flowed through by the fluid from an intended inflow side to an intended outflow side. The secondary filter element has a support element covering the filter medium at the intended inflow side. A filter system with such a secondary filter element is provided.

Embodiments herein relate to filtration systems that can pulse clean filter elements selectively, in specific patterns, to enhance cleaning efficacy. In an embodiment, a filtration system is included having a plurality of filter element mounts configured to retain filter elements, a compressed gas supply, and a plurality of valves in fluid communication with the compressed gas supply. The system further including a control circuit configured to control actuation of the plurality of valves. The system can operate in a first mode and a second mode. Wherein operating in a first mode includes opening valves according to a first valve actuation pattern and operating in a second mode includes opening valves according to a second valve actuation pattern. The system can be configured to periodically switch from the first mode to the second mode and compare the efficacy of the two modes. Other embodiments are also included herein.

Systems, methods, apparatuses, and devices for removal of undesired materials are disclosed. Production of desired materials may result in the production of undesired materials. The systems, methods, apparatuses, and devices, may provide for removal of the undesired materials from various environments (e.g., industrial, commercial, residential, natural, etc.). The undesired materials may be removed in a substantially continuous manner and may limit or prevent contamination of an ambient environment with the undesired materials. The undesired materials may be removed with high-pressure vacuum through a fluid flow path that keeps the undesired materials from the ambient environment.
