A f filter assembly includes a primary filter; a secondary filter into which the primary filter is detachably inserted; a case detachably coupled to the primary filter and comprising a plurality of air inlet holes; and at least one blade being rotatably coupled to the secondary filter and configured to compresses first foreign substances collected in the primary filter based on the primary filter moving in a first direction in which the primary filter is drawn out from the secondary filter.

A control system integrated into an industrial dust collector. The system comprising at least one programmable processing unit which communicates with a plurality of sensors located in the dust collector to provide data of the collector's behavior with feedback allowing real-time modifications to the operating parameters defined during the design. Additionally, a service-life prediction element of used-filters based on a reference chart is included.

A filter assembly for separating and removing a liquid from a compressed fluid stream includes a filter element for separating the liquid from the fluid, a purge valve, and an elongated valve operator for actuating the purge valve. The top of the filter element has a shroud that decreases the flow area of the entering fluid stream to induce a vortex of the fluid, allowing the liquid to separate from the fluid. The purge valve is located at the bottom of the filter element for draining the separated liquid. The elongated valve operator axially extends through the filter element and is moveable by an actuating piston located at the top of the filter element, in response to elevated pressure in the filter assembly. The filtered air is dried through a desiccant body and then outputted from the filter assembly to be used in an air brake system.

A filter holder (2) for a filter element (3) that has an oval-shaped cross section transverse to a longitudinal direction (LR) thereof, with a receiving section (19) for receiving the filter element (3), a fluid inlet (24) for allowing fluid (L) to be filtered into the filter holder (2), and a fluid outlet (25) for letting the fluid (L) filtered with the aid of the filter element (3) out of the filter holder (2), wherein the fluid inlet (24) is arranged such that an inflow direction (E) of the fluid (L) to be filtered is oriented in the direction of a lateral surface (29) of the filter element (3) that can be received in the receiving section (19), whereby the fluid (L) to be filtered flows tangentially around the filter element (3) that can be received in the receiving section (19) in order to separate particles (33) contained in the fluid (L) to be filtered on a wall (30) of the receiving section (19) with the aid of centrifugal force.

A filter receptacle (2) for a filter element (3) that, transversely to a longitudinal direction (LR) thereof, has an oval cross section, said filter receptacle having a receiving portion (19) for receiving the filter element (3), a fluid inlet (24) for allowing fluid to be filtered (L) into the filter receptacle (2), and a fluid outlet (25) for discharging the fluid (L) filtered with the aid of the filter element (3) from the filter receptacle (2), wherein the fluid outlet (25) is arranged such that an outflow direction (A) of the filtered fluid (L) from the fluid outlet (25) is oriented parallel to the longitudinal direction (LR) of the filter element (3), and wherein the fluid outlet (25) has a circular cross section facing away from the filter element (3) and an oval cross section facing toward the filter element (3).

A bathroom management apparatus may include a case having an air suction port formed in an upper portion of a front surface thereof, a first air discharge port formed in a lower portion of the front surface thereof, and a second air discharge port formed in a lower surface thereof. A suction vane opens or closes the air suction port, and first and second discharge vanes opens or closes the first and second air discharge ports, respectively. A duct is provided in the case to connect the air suction port, the first air discharge port and the second air discharge port to one another. A blowing fan is provided in the duct to suck air through the air suction port and blow the air to the first air discharge port and the second air discharge port. A heater heats the air in the duct.

A vertical furnace includes a chamber intended for receiving a loading column an inlet channel for fresh gas, arranged at an upper end of the chamber, the loading column comprising an upper portion, and a central portion for supporting a plurality of substrates. The vertical furnace further comprises a trapping device made of at least one material suitable for trapping all or part of the contaminants present in the fresh gas. The trapping device includes a circular part arranged on the upper part of the loading column, the circular part comprising fins regularly distributed over an upper surface of the circular part in order to increase the contact surface of the trapping device with the fresh gas.

The inventive concepts provide apparatuses for transferring a substrate and/or apparatuses for processing a substrate including the same. The substrate transferring apparatus including a chamber, a filter assembly disposed in a chamber to provide external air into the chamber, and an additional assembly including a moisture removing part and a purge gas providing part sequentially stacked on the filter assembly may be provided. The filter assembly may be coupled to the additional assembly.

A control system integrated into an industrial dust collector. The system has at least one programmable processing unit that communicates with a plurality of sensors located in the dust collector to provide data of the collector's behavior with feedback allowing real-time modifications to the operating parameters defined during the design. Additionally, a service-life prediction element of used-filters based on a reference chart is included.

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. 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.
