ABSTRACT:
A cartridge-filter cleaning spinner comprises a handheld spindle rod that can accommodate a variety of filter sizes. The spindle rod has two inward pointing slip-ring hand-tightened hubs. A cartridge filter is loaded on the spindle rod by removing one of the slip-ring hand-tightened hubs, slipping the cartridge filter onto the spindle snug against the other slip-ring hand-tightened hub, and then reinstalling the first slip-ring hand-tightened hub on the spindle rod. The cartridge filter is then free to spin around while the spindle rod handles themselves remain stationary. A water jet from a garden hose is then directed at one end of the cartridge filter to one side so the cartridge filter begins spinning. The water jet is then worked down slowly to the opposite end while keeping the spinning action going. The process is then repeated, but with the water jet directed to the other side so the cartridge filter spins in the opposite direction. This helps both sides of the longitudinal outside pleats of the cartridge filter material to come clean. The cleaning is accomplished by centrifugal action and does not involve backwashing.
