Horizontal Packed Bed Cross-Flow Fume Scrubber

With decades of experience in the design, manufacture and installation of fume scrubbers we know precisely which fume scrubber will achieve the required outcome for extract applications. Contact us and we will willingly guide you through the process. Our Horizontal Packed Bed fume scrubber is of particular use when multiple stage scrubbing is required or when headroom is limited.

Our Horizontal Packed Bed fume scrubber has the added advantage of minimising pressure drop due to its cross-flow design. This also allows lower irrigation rates, reducing liquor and power consumption.

A typical application of our horizontal fume scrubber is the two-stage control of odours from by-product or food processing units. In many cases acid/alkali scrubbing is followed by oxidation or simple water washing to achieve the desired outlet concentrations.

APMG’s products are manufactured by time-served tradesmen in the plastic fabrication department of our Manchester factory.

Operating principles

Gas enters via a flanged inlet connection to be cooled and saturated by liquor (recycle) from the front bed sprays. These have the dual purpose of removing dust, cooling the gas and maintaining the front face of the bed free from solids.

The gas then passes horizontally through one or more series of packed beds, which are irrigated from above. This allows the gas to be washed with chemically different liquids if required.

Disentrainment of liquor is achieved by passing the gas through a dry section of packing prior to exiting via the stack/fan in a clean but saturated condition. The base of the unit forms an integral recycle tank. We vary the dimensions to suit individual space limitations.


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.
