Abstract
A fluid filter comprising a housing having a central aperture formed in the bottom thereof, a filter element disposed in the housing and arranged to receive a flow of fluid to be filtered from an upstream side of the element to a downstream side thereof, and a fluid inlet and outlet manifold disposed at the bottom of the housing in communication with the central aperture for providing fluid inlet and outlet communication through said aperture with a fluid inlet and a fluid outlet.
Claims24
A fluid filter comprising:
- a housing having an upper opening:
- a movable filter element disposed in said housing defining an upstream space for containing incoming non-filtered fluid and a downstream space for containing outgoing filtered fluid, said upstream space in fluid communication with an inlet and a drain, and said downstream space in fluid communication with an outlet;
- and
- movement means for causing rotational movement of said filter element within said housing;
- wherein said filter element includes elongate filtering means for filtering non-filtered fluid, a central pipe extending axially substantially the length of said housing, and a filtrate collection space located in the upper interior region of said housing, said filtrate collection space being in fluid communication with said elongate filtering means and with one end of said pipe, the other end of said pipe being in fluid communication with said outlet;
- and
- wherein said movement means is connected to said filter element and extends through said upper opening external to said housing, whereby external movement of said movement means moves said filter element so as to permit separation of particles from said filtering element and effective regeneration or clean up of said filter element.

A fluid filter, comprising:
- a housing having an aperture in the bottom thereof;
- filter means for filtering the fluid, located within said housing and separating an upstream space containing incoming non-filtered fluid from a downstream space containing outgoing filtered fluid;
- movement means, penetrating through said housing and connected to said filter means, for causing rotational movement of said filter means within said housing;
- an external inlet, outlet and drain manifold, disposed below said housing and having a neck portion passing through said aperture in the bottom of said housing, said manifold having inlet and drain means in fluid communication with said upstream space through said bottom aperture, for passing incoming non-filtered fluid into the upstream space of said housing and for draining non-filtered fluid from said upstream space, when necessary, and outlet means in fluid communication with said downstream space through said bottom aperture, for passing outgoing filtered fluid out of the downstream space of said housing.

A fluid filter, comprising:
- a housing having a bottom wall with an aperture therein;
- filter means for filtering the fluid, located within said housing and separating an upstream space containing incoming non-filtered fluid from a downstream space containing outgoing filtered fluid;
- an external inlet, outlet and drain manifold, disposed below said housing and having a neck portion passing through said aperture in the bottom wall of said housing, said manifold sealingly engaging the bottom wall of said housing about the aperture therein;
- and
- collar means threadedly engaging said neck portion of said manifold which extends into said housing for holding said manifold in sealing engagement with said housing;
- wherein said manifold has inlet and drain means in fluid communication with said upstream space through said bottom aperture, for passing incoming non-filtered fluid into the upstream space of said housing and for draining non-filtered fluid from said upstream space, when necessary, and outlet means in fluid communication with said downstream space through said bottom aperture, for passing outgoing filtered fluid out of the downstream space of said housing through said bottom aperture.
