A separator system for separating drops and solid particles from an air inlet flow. The separator system includes an air inlet channel opening and a separating body which is internally installed. The separating body is arranged downstream of the air inlet channel opening so as to completely cover the air inlet channel opening and to extend flat in a mounting plane. The separating body is provided as a modular design and includes, in the mounting plane, at least one first separating part, and at least one second separating part which is arranged to be separate from the at least one first separating part.

A fastening module for connecting a filter system to an arched connecting surface with openings for a fluid has a connecting housing connectable in fluid communication to the filter system. Rigid individual channel pieces are arranged in the connecting housing and channels extend in the channel pieces. The channels correspond with the openings in the arched connecting surface. The channel pieces have connecting flanges to be connected to the openings in the arched connecting surface. The channel pieces are connected by flexible connecting regions with each other; with the connecting housing; or with each other and with the connecting housing. The fastening module is connected in fluid communication to the inlet region or outlet region of the filter system. A filter module for the filter system has substantially free intake across its cross section and enables an intake manifold-type distribution of a volume flow passing through the filter element.

A liquid separator comprises a vessel with an inlet for a liquid/gas mixture. The vessel defines a space sealed at the top by means of a lid in which is situated an outlet to discharge treated gas. A shield is provided in the space extending around the outlet as of the lid, and a filter element provided within the shield. An outlet zone is defined between the shield and the filter element, wherein the outlet zone is in connection with the outlet. The shield comprises a bottom wall with at least one inlet opening and connection means for attaching the filter element onto the bottom wall. The connection means is configured such that the filter element, in a mounted condition, extends around the inlet opening as from the bottom wall, within a chamber defined by the shield, the lid and the bottom wall.

Disclosed is a desiccant cartridge (10) for drying and de-oiling a gaseous fluid, and a method for flow guidance within the desiccant cartridge. The desiccant cartridge and a housing (12) having positioned therein an inner pot (28) in which an oil separating medium (50) for oil particles contained in the fluid and a desiccant (52) for drying the gaseous fluid are arranged one after the other in the direction of the housing longitudinal axis (14). The housing (12) has a housing base (18) having a centrally arranged inlet (20) for the fluid to be dried and de-oiled and having eccentrically arranged outlet openings (24) for the dried and de-oiled fluid. During normal operation of the desiccant cartridge (10), the gaseous fluid guided into the desiccant cartridge (10) via the central inlet (20) is first guided in a flow through the oil separating medium (50) and then through the desiccant (52).

A filter module is provided with a filter housing provided with an inflow opening. A filter element with an annular filter medium body with an elongate cross-sectional shape is arranged inside the filter housing. A flow path is defined between the inflow opening of the filter housing and an inflow side of the filter medium body. A swirl device is arranged in the flow path and impresses a swirl onto an incoming fluid. The swirl device is a part separate from an outer wall of the filter housing. The swirl device is arranged axially upstream of the inflow side of the filter medium body. The swirl device is provided with a displacement body arranged inside the filter housing adjacent to the inflow opening. The displacement body forms a flow guiding element.

A filter element is provided with an annular filter medium body and an end disk arranged at an end face of the annular filter medium body. Guide vanes are arranged adjacent to the end disk, wherein the guide vanes extend radially past an outer contour of the end disk and project into a flow path upstream of an inflow side of the annular filter medium body. The guide vanes are held at the end disk.

Radial seal filter assemblies and filter cartridges are described. According to various embodiments, a filter includes a housing that extends along an axis between first and second axial ends. A primary filter element is disposed in the housing and axially extends between first and second axial ends that respectively are adjacent the first and second axial ends of the housing, the primary filter element has a hollow interior and a first axial length. A secondary filter element is disposed in the hollow interior of the primary filter element, the secondary filter element having a second axial length, the second axial length being longer than the first axial length of the primary filter element. The filter further includes an end cap disposed on the second axial end of the primary filter element.

An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.

An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

Method and apparatus are disclosed for filter racks for blower coil units. An example filter rack for a blower coil unit includes a frame. The frame includes a rear frame structure, a front frame structure coupled to and spaced apart from the rear frame structure to define a slot that is configured to house a filter for filtering air flowing from a blow coil unit, and a side extending between the front frame structure and the rear frame structure. The side defines a first opening to the slot to enable the filter to be inserted into and removed from the slot. The example filter rack also includes a magnet fixed along the side and a panel configured to couple to the side via the magnet. The panel securely encloses the filter within the slot when coupled to the side and provides access to the slot when decoupled from the side.
