  • Filter device, air conducting hose with filter element, tunnel, and use of the filter device
    Patent number: 11958009
    Abstract: 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.
