A mist collection and separation assembly is disclosed for improved operability and maintainability. The assembly includes a rotor disposed concentrically within a housing and powered by an electrical motor that generates suction, drawing mist from a target environment into a rotor interior cavity. The mist impacts a rotor surface and reverses direction, causing liquid and potential particulate content to separate due to inertia. Separated matter drains through designated housing ports, while clean air is exhausted. The assembly operates filter-free, reducing maintenance and cost. Vertical orientation enhances separation via gravity, and grooved rotor surfaces facilitate drainage. Wetted internal housing surfaces enable passive self-cleaning through molecular adhesion of submicron particles. Optional removable filters may be included for improved reliability.

Embodiments of the present disclosure provide a natural gas separation device, the device comprising a tank, providing with an air inlet, an exhaust port, and a liquid discharge port; a liquid separation assembly, disposed in the tank and dividing an internal space of the tank into a front separation chamber and a liquid recovery chamber, the liquid separation assembly being provided with a liquid return channel for connecting the front separation chamber and the liquid recovery chamber; and a solid separation assembly, disposed in the front separation chamber and connected to the liquid separation assembly.

A docking station has an openable dirt collection region which, during an evacuation operation of the docking station, receives dirt that is transferred from a surface cleaning apparatus; and a lock having a locked position in which the dirt collection region is secured in a closed position, and an unlocked position in which the dirt collection region is openable. During the evacuation operation, the lock is inhibited from moving to the unlocked position.

The invention relates to a liquid separator for separating liquid from a gas-liquid mixture, having a housing, an inlet, an outlet, a flow path connecting the inlet to the outlet, and a separating device, arranged in the flow path, for liquid separation, wherein a wall body is attached to the inner side of a housing portion adjoining the outlet, surrounds an annular collar projecting into the housing from the outlet, and extends towards a liquid outlet, wherein the wall body, together with a wall of the housing, defines a flow channel so that liquid collected at the outlet can be discharged through the flow channel via the liquid outlet.

An apparatus for machining composite-material workpieces containing metal and non-metal has at least one machine which is used to machine the composite-material workpieces and which isolates shavings containing metal and non-metal or isolates other particles, and a suction and cleaning device for air contaminated with such particles. The suction and cleaning device has a fan and, arranged in fluidic sequence for multi-stage cleaning of the contaminated air, a cyclone separation stage, at least two mechanical filter stages and an activated carbon filter stage. The cyclone separation stage has a packet of at least three, preferably at least six, individual cyclones fluidically connected in parallel, which are arranged around a feed which supplies them via a distribution star. The individual cyclones have upwardly directed outlets for cleaned air; and above the outlets of the individual cyclones, a first of the mechanical filter stages is arranged engaging around the allocated feed.
