ABSTRACT:
Filters, particularly relative small filters, usually include a screening element which readily clogs or becomes partially blocked with material thus impeding the flow of liquid therethrough. The present invention comprises a cylindrical filter housing or bowl portion bisected by a vertically situated screen element situated at an angle to the direction of flow so that the flow of fluid tends to wash the screen and deposit the sediment at the base of the housing. Preferably the housing is formed of clear plastic or glass so that the screen condition can be viewed. The base of the screen element is angulated and lies on the base of the housing upon the inlet side thereof so that when removing the screen for cleaning, any sediment may be lifted clear of the housing as the screen is removed.
