Air purifier

A train station has at least one transportation route for traffic of vehicles, wherein the at least one transportation route is provided with a vehicle tunnel. At least one public waiting area is arranged adjacent to the at least one transportation route. An enclosure is provided in which the at least one public waiting area is arranged, wherein the enclosure has at least one side wall. At least one ambient air purification arrangement for purifying ambient air is provided that has one or more filter units for separating solid, liquid or gaseous ambient air pollutants from the ambient air. The one or more filter units are arranged at and/or in the at least one side wall of the enclosure.

Train station, in particular a tunnel-type train station, and use of a filter unit in a train station

A filter device for ambient air filtration has a blower housing with air inlet and air outlet. A device for generating an air flow is arranged in the blower housing and generates an air flow in operation from air inlet to air outlet. A flexible air conducting hose is provided with a first open end connected to the air outlet of the blower housing and with a second closed end. The flexible air conducting hose has openings arranged between first open end and second closed end. Filter elements are arranged in the openings, respectively. The filter elements separate a raw side inside the air conducting hose from a clean side downstream of the filter element. The air conducting hose is inflated in operation of the device by the air flow. The flexible air conducting hose has a reduced air permeability compared to the air permeability of the filter elements.

Filter device, air conducting hose with filter element, tunnel, and use of the filter device

An ambient air purifying device has a blower housing with air inlet and air outlet. In the blower housing, a flow generating device is arranged generating an air flow from air inlet to air outlet. Between air inlet and air outlet, a filter device is arranged with filter elements arranged relative to each other in a V shape. The blower housing has a servicing door through which the blower housing interior is accessible. The filter device has a filter element support held at the blower housing and supporting the filter elements. The filter element support is pivotably supported about an axis at the blower housing. The filter element support is transferrable from an operating state, in which it is completely inside the blower housing, into a servicing state, in which it projects at least partially through the servicing door from the blower housing, by pivoting about the axis.

Ambient air purifying device and use of a filter element in an ambient air purifying device

A road vehicle with a vehicle frame and a rear axle connected to the vehicle frame is provided with an ambient air purification device with filter elements for removing dust, particulate matter, and gases from ambient air. The ambient air purification device is arranged transverse to a longitudinal vehicle axis in an exterior region of the road vehicle at a vehicle rear of the road vehicle in an underfloor region such that at least the filter elements are arranged behind the rear axle of the road vehicle in a travel direction of the road vehicle. The ambient air purification device is received in an installation space of the vehicle frame. The ambient air purification device is flowed through in longitudinal vehicle direction. A free outflow zone of the ambient air purification device is arranged, in travel direction of the road vehicle, behind the ambient air purification device.

An environmental air cleaning device for a road vehicle removes dust, particulate matter, and/or gases from environmental air. The environmental air cleaning device has one or more filter elements. The environmental air cleaning device is provided with a mounting device that rigidly couples to a vehicle-side mounting device for roof loads. A road vehicle with such an environmental air cleaning device is provided.
