REITHER® venturi scrubber

The REITHER® venturi scrubber, developed by Dr. Diplom-Ingenieur Reither, has a unique design of a double venturi enabling an efficient separation of the finest dust aerosols from 0.3 to 20 µm at very high efficiencies with reasonable pressure drop.

Venturi scrubber

The REITHER® venturi scrubber is designed for efficient separation of the finest dust aerosols. It is equipped with an adjustable throat cross section which maintains a constant pressure drop across the throat and therefore constant separation efficiency, independent of flow rate fluctuation.

See BAYER-REITHER® for a venturi scrubber including hybrid nozzles.


  • Gas flow : up to 250 000 m3/h
  • Particle size distribution : > 0.3 µm
  • Dust concentration : < 1 g/m3

Separation of

  • Superfine dusts (metallic, pigments, flue dust, smoke, silica dust)
  • Acid mists (HCl, H2SO4, H3POV…)
  • Salt aerosols (chloride, fluorides…)
  • Metal oxides (copper, zinc, lead, titanium…)
  • Non adhesive agents (Al(OH)3…)


  • Chemical manufacturing (incineration/boiler…)
  • Metallurgic industry (iron & steel, metal smelting, metal finishing & plating)
  • Pharmaceutical plant
  • Pesticides plant
  • Paint & coating industry
  • Food & beverage industry (atomizer, dryer…)


  • Simple and compact design
  • Cost effective
  • High collection efficiency on superfine dusts and aerosols with low pressure drop
  • Controllable on different flow patterns, dust loads, etc…
  • Simultaneous absorption of gaseous pollutants possible
  • Adjustable venturi throat – manual or automatic
  • Handles high inlet gas temperatures
  • Non-clogging
