Venturi Fume Scrubber

Based on decades of practical experience, APMG Plastics is able to supply a range of Venturi fume scrubber designs for use where very small (1 – 5 µ) or sub-micron (0.05 – 0.9 µ) particulates must be removed from the air stream. High pressure drops (1 Kpa – 12.5 Kpa) are required and the smaller the particulate the higher the pressure drop. 

Processes which would employ this type of fume scrubber are those where condensation of liquids or metallic vapours occurs or when chemical reactions result in the formation of a fine fume such as ammonium chloride.

Speak to our friendly team of experienced designers who can advise on which Venturi fume scrubber is appropriate for your needs. All our wet scrubbers are manufactured by time-served craftsmen in our Manchester-based factory.

Operating Principles

A Venturi fume scrubber consists of an external venture section and a separator. Gas and liquid streams are accelerated through the Venturi throat, causing the particulates and scrubbing liquor to agglomerate into droplets of sufficient size to be separated from the stream by the separator.

A major advantage of this type of unit is its simplicity with no internal devices that can block.


APMG Plastics also designs, manufactures and installs an extensive range of ductwork and vent fittings to complement our range of corrosion resistant Durafan extract fans. All pipework is manufactured to meet HVAC DW/154 Specification for Plastics Ductwork, which is the premier specification for PVC and PP-S ducting.
