This range of filters operates in the same way and is produced in the same materials as the manual mesh filters. The difference comes in the filtration level, which here is far greater. Filtration is achieved through the physical retention of larger particles by the filter element, which for this type of filter is perforated stainless steel plate. The filter element is cleaned manually (though the process can be automated). High efficiency is guaranteed thanks to the large filter area and reduced load loss.
