A DuraFilter system is mounted on the mobile unit, which can be equipped with a plastic extraction arm, such as the Flex or UltraFlex, or a flexible hose. For welding on the spot, mobile units are ideal. Standard on the system is a filter indicator, which shows if the extraction is still satisfactory or if the filter needs to be changed.
