A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally comprises z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.

A removal system is provided with a separating element for separating contaminants contained in a fluid and with a removal aid for removing the separating element from a housing. The separating element has an end disk arranged at an end face of the separating element. The end disk has a central recess. The removal aid has a grip section and at least two locking fingers. The locking fingers extend along a center axis of the removal aid away from the grip section. Each locking finger has a hook element that serves for engaging behind the end disk of the separating element radially outside of an end disk area that delimits in radial outward direction immediately the central recess. A removal aid for such a removal system is provided.

A fluid filter has a filter housing with inlet opening for fluid to be cleaned and outlet opening for cleaned fluid. A filter element arranged in an element receptacle of the filter housing separates inlet opening from outlet opening. The filter housing has a housing body with an installation opening to the element receptacle, through which the filter element in an installation direction is introduced into the element receptacle. The filter housing has a housing cover for closing the installation opening. The installation opening is arranged in a transverse side of the housing body that is lateral relative to the housing axis. The filter housing has a sealing surface, surrounding the housing axis at least partially circumferentially, for contacting a seal of the filter element. The filter element has a seal support device for the seal and the filter housing has a pressing device for the seal support device.

A room air purifier including upper and lower portions with the lower portion including a detachable floor panel. The upper portion and the floor panel may respectively include integrated resilient upper and lower gaskets configured so that with an air filter removably installed in the room air purifier and with the floor panel attached to a lower housing piece of the lower portion of the room air purifier, the upper portion of the room air purifier, and the floor panel, apply pressure to the air filter through the upper and lower gaskets.

A filter arrangement for filtering dust-laden air generated by a hand-guided power tool having a motor features a filter cartridge having a hollow casing with a longitudinal extension along a longitudinal axis, a hollow filter element located inside the hollow casing, having a longitudinal extension along the longitudinal axis, an air inlet port in the hollow casing, pneumatically connected to the power tool to allow the dust-laden air generated by the power tool to flow into the hollow casing, and an air outlet port in the hollow casing, to allow filtered air to leave the filter cartridge. An external chamber of the filter cartridge is formed between the hollow casing and the hollow filter element. An internal chamber is formed inside the hollow filter element. The internal chamber is closed by a conical head portion at a first end of the internal chamber facing towards the air inlet port. The external chamber is in pneumatic connection with the air inlet port and the internal chamber at a second end opposite to the first end is in pneumatic connection with the air outlet port. The filter arrangement includes an active airflow generating device being in pneumatic connection with the air outlet port and the internal chamber of the filter cartridge in order to generate or support the airflow through the filter cartridge.

An air cleaner includes a case, an air inlet, an air outlet, a grill covering the air inlet to filter airborne oil droplets, a fan to suction air through the air inlet and discharge air out of the air outlet, a roll filter provided between the grill and the fan to filter oil mist, and a filter roller to cut the roll filter. The roll filter includes a roller and a filter sheet wound around the roller, and the filter sheet may be unwound to extend behind the grill. When the filter sheet becomes dirty, the roll filter is further unwound so that a clean section is provided behind the grill, and the filter cutter may cut off the dirty section. During cutting, a clamp holds down the filter sheet. The case includes a slit through which the dirty section of the filter sheet passes for discarding.

A filter equipment includes a main body portion which has a hollow columnar structure with an open upper portion and a closed lower portion, and has a plurality of air inlets formed on a side surface to be spaced apart at regular intervals; a top cap which is detachably attached to an upper opening surface of the main body portion, and has a doughnut structure having a width corresponding to that of the filter portion in a plan view, a magnetic member attached to a lower surface of an air vent by a magnetically detachable structure being mounted on an upper surface of the top cap; a filter portion which has a hollow columnar structure corresponding to an inner peripheral surface of a main body portion, has a doughnut structure having a width corresponding to the lower surface of the top cap, has a structure that is in close contact with the lower surface of the top cap, purifies the air drawn in from the air inlet of the main body portion and then makes the purified airflow through a central opening portion of the top cap to the air vent; and a safety wire which is mounted inside the main body portion and extends by a predetermined length to be combined with one side of the top cap.
