An air cleaner is provided. The air cleaner may include a first air cleaning module including a first fan, a first filter, and a first inlet through which air is suctioned in a radial into the first filter; a second air cleaning module provided over the first air cleaner including a second fan, a second filter, and a second inlet through which air is suctioned in the radial direction to the second filter; and an air flow controller coupled with the second air cleaning module and including a third fan to control a flow of the air discharged from the second air cleaning module.

Rotating coalescer elements that maximize the radial-projected separation surface area in a given (rotating) cylindrical volume, where flow to be cleaned is passing axially upward or downward through a separating media of the rotating coalescer element. Various example package assemblies are provided with various types of rotating configurations including cylindrical coiled media packs, frustum coiled media packs, concentric cylinders, coiled metal or polymer films with and without perforations, and/or alternating layers of different materials. The described rotating coalescers may be driven by hydraulic turbine, electric motor, belt, gear or by mounting on rotating machine components, such as rotating engine shafts or connected components.

Disclosed is an air cleaning machine, which mainly comprises a hollow tube body, a detect chip, an adsorbent material, a large shell body and two air outlet assemblies, the air circulation is formed through a plurality of holes disposed on an underside of the large shell body and a round hole disposed on the side of the large shell body, so the air is able to flow through via an air hole disposed on the one side of the fixing sheet of the hollow tube body. Thus, the detect chip arranged closely to the air hole of the fixing sheet on one side of the hollow tube body can detect the concentration of the suspended particles (PM2.5) in the air.

A coalescence filter including an inlet for supplying the gas to a filter element present in the coalescing filter, which filter element includes a coalescence medium for coalescing at least one disperse liquid phase during a displacement of a gas through the coalescence medium in a flow direction. The filter element downstream of the coalescence medium includes a drainage medium for draining the at least one coalesced disperse phase leaving the coalescence medium. The filter element contains a barrier layer positioned downstream of the coalescence medium, where the coalescence medium and the barrier layer are held at a distance from each other by one or more spacers to provide a drainage zone in the drainage layer of a drainage medium between a surface of the coalescence medium facing the barrier layer and the barrier layer for draining the coalesced disperse phase in a drainage direction.

An operation mode of an air cleaner is changed according to the degree of indoor air contamination and an indoor space condition, and one or more filters of the air cleaner can be easily cleaned. The air cleaner includes a housing, an inlet located at a lower part of the housing, a filter assembly, an outlet, and a brush unit. The filter assembly is located above the inlet, and a diameter of the filter assembly is gradually shortened in the direction from an upper part of the filter assembly to a lower part of the filter assembly. The discharge port is located above a second filter assembly. The brush unit is used to eliminate contaminants from an outer surface of the filter assembly.

An air cleaner is provided that may include a first air cleaning module including a first fan that generates air flow toward a first discharge outlet from a first suction inlet; a second air cleaning module including a second fan that generates air flow toward a second discharge outlet from a second suction inlet; and a divider provided between the first air cleaning module and the second air cleaning module, the divider being configured to block air discharged through the first discharge outlet from being suctioned into the second suction inlet.

The present invention provides an air purifier including a plurality of bi-directional fans, which are arranged to be misaligned in a vertical direction such that the discharge directions of discharge ports are different from each other.

An indoor unit includes axial-flow fans, which are provided on downstream of an air inlet. Further, a plurality of first bars are provided to the air inlet. In plan view, leading edge portions of blades of the axial-flow fan are inclined in a direction of rotation of the axial-flow fan from a rotary shaft side of the axial-flow fan to an outer peripheral side. Further, in plan view, the plurality of the first bars are inclined in a direction opposite to the direction of rotation of the axial-flow fan from the rotary shaft side of the axial-flow fan to the outer peripheral side.

An air purifier (1) with mount for a vehicle, wherein the air purifier (1) consists of a fan in a portable housing (2, 4, 5), which has at least one air intake region (45) for sucking air into the housing (2, 4, 5) and at least one air discharge region (50) for blowing the air out of the housing (2, 4, 5), wherein a cleaned discharge air flow (51) flows out into the passenger compartment, wherein the mount consists of an adapter plate (6) that can be detachably fixed in different positions in the interior of the motor vehicle, and wherein the air purifier (1) is rotatably mounted in the adapter plate (6).
