Abstract
A filtering system for swimming pools includes a cylindrical filter housing in which a filter bag is supported in a perforated liner. A skimmer housing is mounted on the cylindrical housing and skims water off of the surface of the pool, which communicates to the inlet chamber through a perforated skimmer basket which catches debris floating on the surface of the pool water. The main drain of the pool is connected directly to the inlet chamber. An outlet of the cylindrical housing communicates directly with the inlet port of a pump that returns filtered water to the pool.

Swimming pool filter comprising a housing having an inlet chamber for receiving water from said swimming pool for filtering and an outlet chamber, a skimmer inlet extending across the surface of the water in said pool, said skimmer inlet communicating with said inlet chamber, and a pump having an inlet communicated with the outlet chamber, said housing having an inner circumferential surface, a perforated liner offset from said inner circumferential surface of the housing, and a filter bag supported by said liner and having an open end receiving water from said skimmer inlet and from said main drain inlet, said pump drawing water from said inlet chamber through said filter bag and said perforated liner whereby the water is filtered by said filter bag.
Swimming pool filter system comprising a filter and a pump, said filter including a housing having an outlet chamber and an inlet chamber for receiving water from said swimming pool for filtering and an outlet chamber, said housing including a skimmer inlet extending across the surface of the water in said pool and communicating water in said pool into said inlet chamber, said inlet chamber being separated from said outlet chamber by filtering media, said pump having an inlet port communicated to the outlet chamber of said housing and a discharge port for returning filtered water to said pool.
Fluid filter assembly comprising a circumferential housing defining a volume therewithin, said housing including a pair of inlet ports and an outlet port, a filtering media within said housing dividing said volume into an inlet chamber communicated with said inlet ports and an outlet chamber communicated with said outlet port, and a perforated basket within said housing between said inlet ports for straining fluid communicated through one of said inlet ports before passing to said filtering media while allowing fluid communicated through the other inlet port to bypass said basket and pass directly to said filtering media.
