Full Title
Full titles differ between systems:
IPC:
Filters with filtering elements which move during the filtering operation > with multiple filtering elements characterised by their mutual disposition > in parallel connection > concentrically or coaxially
CPC:
Filters with filtering elements which move during the filtering operation (filters comprising loose filtering material moving or fluidised during filtration B01D24/28 - B01D24/36; centrifuges B04B) > with multiple filtering elements characterised by their mutual disposition ( , B01D33/21 take precedence) > in parallel connection > concentrically or coaxially
No child classifications to compare. This is a leaf node in both IPC and CPC.
