A cyclone for the separation of solid particles and/or at least one liquid from a fluid, featuring a housing, an inlet opening for introducing the fluid together with the solid particles and/or the at least one liquid into the housing, a discharge port for the solid particles and/or the at least one liquid, a dip tube for discharging the fluid from the housing, and at least two guide vanes. Each guiding vanes shows a geometrical form with at least three edges e1, e2, e3. Further, each guide vane is directly or indirectly fixed to the housing with at least one edge e3 at a fixing point, whereby an area a is defined as the cross-sectional area of the housing intersecting the fixed edges e3. In addition, each guide vane shows at least two edges e1 and e2 which are not fixed to the housing, whereby the first edge e1 has a distance d1 and the second edge e2 has a distance d2, and whereby d1<d2 to the centerline c of the housing. According to the invention, the first edge e1 shows a distance L1 to the area a and the second edge e2 shows a distance L2, whereby L2>1,25*L1.

A filter (10) has a port block (13) provided with: an inflow port (11) to which compressed air is supplied; and an outflow port (12) from which purified compressed air flows out. A filter container (14) is attached to the port block (13), and an element assembly (30) is disposed inside the filter element (31). The element assembly (30) has: a filter element (31); and an air guide member (41) provided inside the filter element (31). The compressed air filtered through the filter element (31) is guided to an inner surface of the air guide member (41) through a slit (46).

A separator unit includes a tank defining an internal volume and having an inlet and an outlet. An insert is provided within the tank, the insert including a down cylinder substantially centrally disposed within the tank and a baffle assembly at an external side of the down cylinder. The baffle assembly defines first and second inlet flumes for flowing incoming water from an external side of the down cylinder to an internal volume within the down cylinder. Inward ends of the first and second inlet flumes are positioned and oriented to create first and second vortex flows that progress downward within the internal volume, wherein a rotational direction of the first vortex flow is opposite a rotational direction of the second vortex flow in top plan view.

A separator apparatus is described for separating liquids and solids from a gas. The separator apparatus includes a reverse flow cyclone comprising a cylindrical section, a conical section, and a top, the cylindrical section having a feed inlet, the top having a gas outlet, and the conical section having a reject outlet at the bottom thereof. An axial cyclone is disposed in the cylindrical section, the axial cyclone oriented with a first end located proximate to the top of the apparatus and a second end opposite the first end, the axial cyclone having a tapered entrance fixture at the second end thereof and having a wall with a plurality of openings located between the first end of the axial cyclone and a midpoint of the axial cyclone. A drain plate is coupled to the cylindrical section below the openings of the axial cyclone.

An asymmetric inlet particle separator system (AIPS) includes a bifurcated duct system that defines an inlet for receiving inlet air. The bifurcated duct system includes a core air channel and a scavenge air channel and is configured to separate the inlet air into core air and scavenge air. The scavenge air channel includes a first plurality of turning vanes configured to turn the scavenge air in a first direction and a second plurality of turning vanes configured to turn the scavenge air in a second direction. The AIPS also includes an asymmetric scroll coupled to the scavenge air channel. The asymmetric scroll includes a first arm having a first arm length and a second arm having a second arm length that is different than the first arm length.

A cyclone filtering device includes first and second filters. The first filter includes a first filtering tube defining a first turbulence room, and has a coupling cover communicated with the first turbulence room and disposed for allowing passage of fluid, and a barrel seat defining a dust collecting room that is communicated with the first turbulence room. The second filter includes a second filtering tube defining a second turbulence room that is communicated with the first turbulence room, two end covers having an end opening that is communicated with the second turbulence room, and a capture member disposed in the second turbulence room and disposed for capturing substances that are entrained in the fluid.

An apparatus for contaminant reduction in a stream of compressed gas is disclosed. The apparatus includes an insert for directing the gas. The insert sits in a head portion which has an inlet leading to an inlet pathway for directing the gas towards the insert. The head portion also has an outlet leading from an outlet pathway for directing the gas from the insert towards the outlet. There is also a body portion sealed to the head portion for collecting contaminants removed from the gas. The insert includes a tubular portion connected to the head portion. Gas from the inlet pathway passes outside the tubular portion while gas going to the outlet passes inside the tubular portion. The insert has a baffle extending from the tubular portion for narrowing the gap between the insert and the body portion and has curved walls extending from the baffle causing the stream of gas to rotate thereby form a vortex.
