These spaces are effectively dead spaces or backwaters, so the collected contaminants are protected from the pressure in the flow channels - hence there are no problems with wash-off. The size of the channels is designed to be 110% of the entrance diameter, so that there is no ‘choke’ on the flow, and the pressure drop is negligable. Because the Magnom™ is immune to pressure, it can actually work on the suction side of powerful pumps - the only filter able to provide effective protection to this critical components. The collection areas are actually three dimensional spaces, and so the unit can collect and safely store several times the contaminant of a conventional barrier filter, and all without impeding flow. There are no moving parts to seize up, and no papers to split with disasterous consequences for down stream machinery.
