ABSTRACT:
A fluid filter which comprises a canister having an open end and a closed end, the canister sealing to an adapter body to prevent leakage between the canister and the adapter body, the adapter body having a plurality of angled fluid inlet ports extending through the adapter assembly body into the cavity formed by the canister and the adapter body assembly, a threaded fluid outlet port extending through the adapter body, a threaded ring adapter for adapting the outlet port to a variety of filter receptacles, a multistage wire mesh filter element having a weave which is designed to prevent fluid contaminants from passing through the filter element while inhibiting the contaminant particles from becoming lodged in the filter mesh, the fluid inlet ports in the adapter body being formed at an angle to create a tornado type turbine fluid motion within the canister to suspend contaminants which are blocked from passage through the screen in the fluid and allow such contaminants to settle in the canister out of the flow path of fluid being filtered, a sediment chamber formed in the canister by a sediment trap, a relief valve assembly in the canister to allow fluid to bypass the filter element in the event the filter element becomes clogged, an anti-siphon valve in the fluid filter to prevent unfiltered fluid from being flushed from the filter, a switch for warning of a filter which needs to be removed and cleaned, and a magnetized drain plug to assist with contaminant removal from the fluid and allow the canister to be drained prior to removal to reduce injury and spillage.
