A particle separator for cleaning a gas stream loaded with particles may include a gas stream inlet at which the gas stream enters the particle separator with an inflow direction, a gas stream outlet at which the gas stream leaves the particle separator, a closed state in which gas flow from the gas stream inlet to the gas stream outlet is prevented except for a leakage flow, at least one opening condition in which, in addition to the leakage flow, a large volume flow is permitted from the gas stream inlet to the gas stream outlet, a deflection guide between the gas stream inlet and the gas stream outlet, which deflects the large volume flow and/or the leakage flow with respect to the inflow direction, and a textile arranged such that at least part of the deflected large-volume flow and/or the deflected leakage flow impinges on the textile.

A pressure tank condensation separator having an interior chamber forming a downflow path on a first side and an upflow path on a second side passing through horizontally positioned shelves; each shelf having at least one passageway positioned to cause a tortuous air path wherein moisture is separated and deposited on each shelf. The shelves are sloped, leading to drain holes for directing moisture collected to a purge valve. The removal of moisture is most beneficial to clean radar sensors, LIDAR and video cameras used on autonomous vehicles.

An impactor separator comprises a housing having an inlet receiving a gas-liquid stream and an outlet expelling a gas stream. The impactor separator also includes an impaction surface positioned within the housing and configured to separate liquid particles from the gas-liquid stream and a nozzle assembly positioned within the housing. The nozzle assembly includes a nozzle assembly housing portion and a plurality of nozzles extending through the nozzle assembly housing portion. Each of the plurality of nozzles includes a nozzle inlet and a nozzle outlet. The gas-liquid stream enters into the nozzle assembly housing portion, flows into the plurality of nozzles through the nozzle inlet and exits the plurality of nozzles through the nozzle outlet. The plurality of nozzles accelerates the gas-liquid stream toward the impaction surface.
