Zero Gravity Filtration Technology
Home > Zero Gravity Filtration Technology Cross filters are the result of years of research and development into the manufacture of a coil which can filter solid particles efficiently and minimise the use of liquid during backwashing.
The innovative design and manufacturing process produces a coil that has two distinct functions: Precise filtration
 Raised nodes on the surface of the coil ensure a precise filtration gap, allowing fluid to pass through but trapping any particles above the specified filtration rating.
Opening for cleaning
 Left:
A conventional coil, shown here extended, opens with uneven gaps along its length, presenting unequal openings to the flow during backwashing. Right: The patented ‘Zero Gravity’ coil opens evenly along its length during the backwash process. The result is complete and thorough cleaning with the minimum use of liquid. 100% cleaning with every backwash
 The ‘Zero Gravity’ coil design enables filter elements to be completely cleaned with every backwash, minimising backwash frequency and liquid use.
The aircraft quality stainless steel coil is assembled onto an all-stainless steel cage to produce the filter element that is integral to all of the Cross filter range. Filtration ratings
Filter elements are available in ten different micron ratings: 10, 20, 35, 50, 75, 100, 125, 150, 200 and 400 and are completely interchangeable. In heavily contaminated systems, it may be advantageous to install a set of coarse or 'commissioning' elements in the early stages of the filter operation and replace them with finer elements after the backwash frequency has stabilised. |
