A cluster of closely spaced cyclones are arranged with their axes in parallel spaced relation, and cylindrical portions of the cyclones form rigid connections between parallel walls which define a chamber for directing fluid into corresponding tangential inlets within the cyclones. In one embodiment, the walls are formed by flanges molded as integral parts of the plastic cyclone bodies, and the flanges are interconnected by key members. In another embodiment, the walls are formed by flat plates which are rigidly connected by independently removable molded plastic bodies having integral threads. Each of the cyclones includes a replaceable apex cone section which may be ceramic and has an externally threaded portion projecting into an apex discharge chamber defined between an inner wall and a parallel spaced transparent outer wall. Each apex cone section is secured to the inner wall by a nut member, and the transparent outer wall is provided with an axially aligned opening and valve for each cyclone for introducing a back flushing fluid or to produce a vacuum at the apex end. The apex cone sections may be secured to the apex discharge housing by threaded sleeves which also form spacers between the walls of the housing and which support corresponding transparent rings. A ceramic probe is adjustable axially within each ring and has a conical inner end which cooperates with the apex end of the corresponding cyclone to define an adjustable annular discharge orifice. The opposite ends of the cyclones have molded plastic closures with vortex finders which project into a vortex chamber defined by a removable cover member. The vortex finders may also project into a tank connected to a vacuum source for deaerating liquid which is received within the tank.
