This means that the working medium to be cleaned not only flows through the filter in a certain direction, but also through the working medium to be cleaned the filter walls get inside the filter and are led away from there. As a result, most of the surface of the filter is available for filtering, so that the actual filter area is considerably enlarged. For this reason, the entire device can also be kept smaller.
