Abstract
A filter assembly for filtering water in an aquatic structure having a housing with a flow inlet and a flow outlet and filter media between the flow inlet and the flow outlet. A vortex distributor is supported in the housing to distribute fluid evenly over the filter media and partially separate debris from the fluid. The vortex distributor has a conically shaped body portion with an upper side, a lower side and a vortex opening. The vortex opening is substantially centered in the body portion and a plurality of vanes are supported on the upper side of the body portion around the vortex opening, the vanes curving away from the vortex opening to form a substantially planar upper surface.
Claims19
A filter assembly for filtering water in an aquatic structure, comprising:
- a housing having a flow inlet and a flow outlet;
- filter media supported in the housing between the flow inlet and the flow outlet so that fluid entering the flow inlet will flow through the filter media and out the flow outlet;
- and
- means supported in the housing for distributing the fluid substantially evenly through the filter media.
A filter assembly for filtering a fluid such as water in an aquatic structure, comprising:
- a canister housing having a flow inlet and a flow outlet;
- filter means disposed in the canister housing between the flow inlet and the flow outlet for filtering fluid passing from the flow inlet to the flow outlet;
- means supported in the canister housing for distributing the fluid substantially evenly over the filter means and for separating debris from the fluid entering the flow inlet.
A filter assembly for filtering a fluid such as water in an aquatic structure, comprising:
- a canister housing having a flow inlet and a flow outlet;
- filter media disposed in the canister housing between the flow inlet and the flow outlet so that fluid entering the flow inlet will flow through the filter means and out the flow outlet;
- a vortex distributor having fluid communication between the flow inlet and the filter media and supported in the canister housing distributing fluid substantially evenly over the filter media at least partially separating debris from the fluid entering the flow inlet, the vortex distributor comprising:
- a body portion substantially conically shaped and having an upper side and a lower side, and having a vortex opening with fluid communication between the upper side and the lower side;
- and
- a plurality of vanes supported on the upper side of the body portion.
In a filter assembly having a housing with a flow inlet and a flow outlet, filter media supported for fluid flow there through from the flow inlet to the flow outlet, an improved fluid flow distributor comprising:
- a body portion that is substantially conically shaped and having an upstream side and a downstream side with a substantially centrally disposed flow passageway opening providing fluid communication between the upstream side and the downstream side;
- and
- a plurality of vanes extending from the body portion on the upstream side, the vanes extending from near proximity to the flow passageway and radially curving away from the flow passageway, the vanes disposed to direct the fluid flow to be substantially evenly distributed through the filter media.
