  • COMPONENT FOR A FILTER UNIT, FILTER UNIT, AND AIR PURIFICATION SYSTEM
    Publication number: 20260158421
    Abstract: A component for a filter unit includes a nozzle element having a first diameter adjacent the filter unit, where the nozzle element has a second diameter, the second diameter being larger than the first diameter so that a resistance to an air flow from the filter unit is reduced by the nozzle element. The component for the filter unit includes an air-guide element configured to at least partially accelerate an air pulse into the filter unit in order to increase a cleaning performance in the filter unit.

  • COMPONENT FOR A FILTER UNIT
    Publication number: 20260145108
    Abstract: A component for a filter unit, where the component is arranged in an air stream that flows through the filter unit at least in part, and where the component comprises a plurality of profiles at least in a predetermined region. The plurality of profiles are arranged relative to one another on the basis of a predetermined pattern, where the plurality of profiles are configured at least in part to form a turbulent boundary layer in order to reduce a flow resistance of the air stream at the component.
