A fluid filter removal device includes a fluid catch configured to circumscribe an outer surface of a fluid filter, a filter spacer configured to maintain a minimum separation between the outer surface of the fluid filter and an inner surface of the fluid catch when at least a portion of the fluid filter is circumscribed by the fluid catch, and a fluid filter sheath, fixed and hydraulically sealed to the fluid catch proximate the filter exit end of the fluid catch. The fluid filter removal device provides a device and method for removal of oil or fuel filters, and to contain contaminated fluids, on automotive, heavy and other types of equipment to eliminate contamination to the environment as well as contamination to vehicles and users changing a fluid filter.

This invention is directed to a filter removal tool comprising: a cup configured to engage with a filter so that rotating the cup rotates the filter; a shaft having a bore and extending through the cup at a proximal end of the cup; a puncture cap removably attached to the shaft and configured to be received in the cup and to puncture the filter when the shaft transitions from a first position to a second position; a lateral puncture cap opening defined in the puncture cap in fluid communication with the bore; and, a removal tool portion carried by the cup configured to receive a tool for rotating the cup.

A filter module for a gravity-based water purification device is provided. A filter module for a gravity-based water purification device, according to one embodiment of the present invention, comprises: a support frame including a loop-shaped edge member, which includes an empty space of which both sides are open, and a dividing member, which is coupled to the edge member so as to enable the empty space to be divided into a plurality of storage spaces; a pair of filtering members which are formed in a plate shape having a predetermined area, and which are coupled to the support frame so as to enable filtered water to be produced from raw water moving from the outside toward the plurality of storage spaces; and water-collecting ports for discharging, to the outside, the filtered water stored in the plurality of storage spaces, wherein the plurality of storage spaces communicate with each other through at least one communication passage formed at the dividing member.

The invention pertains to a water filter unit with an integrated lifting system, comprising a water filter, at least two lifting pillars, at least two sleeves and a slide connector wherein the sleeves are attached at the corners of the water filter, the length axis of the sleeves being perpendicular to the mounting surface of the water filter, the lifting pillars are arranged to fit inside the sleeves, wherein the length axis of the lifting pillars coincide with the length axis of the sleeves, such that the sleeves may slide along the lifting pillars, thereby forming at least two lifting pillar and sleeve pairs, wherein the at least two pairs are connected to at least one lifting aid for lifting the water filter unit from an operative position to a raised position, and the slide connector comprises a filter side connector connected to the water filter unit arranged for connection to an external source thereby forming a fluid connection between the water filter unit and the external source when the water filter unit is lowered into the operative position. Furthermore, the invention discloses a lifting system for a water filter unit.

An adaptor device for retrofitting in a filter housing is disclosed. The adaptor device allows the filter to be retrofitted with a plurality of filter elements, thereby improving its filtering efficiency.

A device and method for determining a filter element is approaching an end of life obtains vacuum data corresponding to a vacuum at a filter element, and concludes the filter element is approaching an end of life based on the vacuum data as it relates to time in service. The end of life of the filter element may be based on detection of a knee in a vacuum curve derived from the vacuum data, high and low vacuum measurements over a specific time period deviating from one another by more than a prescribed amount, or high and low vacuum curves derived from the vacuum data trending apart from one another by more than a prescribed amount.

The present disclosure provides a filter tray and filter tray assembly with removable filter media. The filter tray may include a quick-release retainer or spring-clip pivotally engaged with the tray and engageable with the tray to form a pressure fit over a filter medium. The filter tray may further include or interface to a handle extension and/or a removeable handle for manipulation of the filter tray, including removing and replacing the filter tray in a deep fryer cooking system.

An in-tank filter assembly for an industrial fluid reservoir tank includes a two piece filter assembly mount comprising an upper filter mount and a lower tank extension member; an element and bypass plate; a bypass structure within the element and bypass plate; a filter element mount coupled to the element and bypass plate; the disposable filter element removably coupled to the filter element mount, wherein the filter assembly forms a bowl-less in tank return line filter having inside-out flow; and an inlet closing valve configured to selectively close off the inlet and biased toward a closed position, wherein the inlet closing valve is configured to automatically close off the inlet when the disposable filter element is removed from the filter element mount.

A catch basin stormwater filtering apparatus includes a support frame and a filter medium supported by the support frame. The support frame includes a planar upper plate and a planar lower plate disposed below and in close proximity to the upper plate. The upper and lower plates have substantially the same outer dimensions, and the support frame defines a central opening. The filter medium is in the shape of a basket and includes lateral side walls of which adjacent walls are joined together, and a bottom wall, the lateral side walls defining a top opening which is disposed in alignment with the central opening of the support frame. The filter medium also includes a flange that extends outwardly from the lateral side walls at the top opening of the filter medium. The flange is interposed between and adhesively joined to the upper plate and the lower plate of the support frame.
