DESCRIPTION

Leistung’s auto cleaning filtration systems have a filter housing, a strainer element, a self-cleaning mechanism, supports and required accessories. The filter housing contains a wedge wire strainer element. Unfiltered fluid enters through inlet. Solids are deposited on the interior surface of the filtration screen of the strainer element and filtered fluid exits at the outlet. When the media requires cleaning (based on time set with fully automatic control or selected manually with semi-automatic control), a spring loaded cleaning disc (wiper) travels down and up, wiping the media clean of concentrated solids in both strokes. Once the debris are removed from the slotted screen, the cleaning disc directs the contaminant to the bottom of the housing and out of the flow path. This cleaning process happens while the filter remains in service, thereby maintaining process efficiency and reducing loss of valuable product. The operation of wiper can be controlled by an on/off switch and a speed controller. When the filter is provided with fully automatic operation control, additional feature such as timer based operation and automatic purging are also available.
