Abstract: A system for filtering water in a spa that provides safety and greater filtration. The system may include a filter secured to a core. The core may include first and second cages with a plurality of openings allowing water to freely pass through the filter and core while preventing larger objects from passing through. The first cage may provide an orientation feature to position the filter in one direction. The second cage may hold mineral cartridges. The core may be secured to a fitting that is secured to the suction line of a spa via a ratchet like engagement feature. The fitting and core prevent back out of the core unless manually overriding the arm on the core which engages fins on the fitting. The filter may be removed and replaced while the core remains in place providing safety to the user. A cap secures the whole assembly into place.

Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

Abstract: A device for cleaning liquids or gaseous media, having a cup-shaped or pot-shaped housing, having an exchangeable interior precipitating element, a medium inlet for medium to be cleaned, a medium outlet for cleaned medium and a housing cover, removably connected to the housing by a connection. The housing has a first circumferential connector and the housing cover has a compatible second circumferential connector, which can be engaged and disengaged by circumferential twisting relative to each other. The first connector or the second connector have at least one interruption extending in the connector axial direction and the precipitating element has at least one positioning arm which, in the installed state of the precipitating element and when the housing cover is connected to the housing, is received at least partially in the at least one connector interruption, in a position and orientation corresponding to the connector interruption.

Abstract: A liquid filter having a housing with a removable screw lid and an interchangeable filter unit, the housing having a discharge channel, wherein a closure valve which when installed is fixed to the housing, is axially adjustable between a closed position when the filter unit is installed and the lid is closed, and an open position when the lid is detached and the filter unit is removed, and wherein releasable coupling elements are provided between the lid or filter unit and the valve. The coupling elements engage to transmit torque and tensile forces, by rotation in the loosening direction of the lid, for as long as a seal of the valve which exerts a braking moment on the valve is located in the sealing seat. The coupling elements disengage when the seal has departed from the sealing seat and the valve is thereby freely rotatable about its longitudinal axis.
