Dry Dust Filters

41 Machines for sale (view all)

Important for safety and comfort for many manufacturers, dust extraction systems are required to collect the by-product dust that is produced by manufacturing processes. To manage the most common type of dust, dry dust extractors are perfect for filtering heavy dust with large particle sizes.

Available in two designs, the extractors Riley Surface World stocks come with filters or cartridges to separate the dust from the air. Both types of dust collector have their own cleaning system to discharge the dust they collect, dry dust extractors with filters typically have a shaker cycle while cartridges would reverse pulse, the dust collecting in a hopper below.

Our warehouse stocking quality machines from trusted OEMs like Donaldson Torit, Filtex & Camfil Farr.

Wet Dust Filters

For dust that is light, sticky or combustible, wet dust extractors are the safest and COSHH approved method for filtering. The particles of dust in these types of air are either too small, adhesive or explosive to be able to be processed in a dry dust extractor. Wet Dust Extractors are available in three designs; cyclonic, centrifugal-type scrubbers & Venturi scrubbers.

Cyclonic and centrifugal scrubbers process the air by directing it around the circular interior of the machines, combining it with water by spray nozzles & misters. The finer the water application at this stage the more thorough the dust extraction process. With the dust from the air wet, gravity pulls the captured dust down to the bottom of the main chamber into a sludge tank.

In wet scrubbers, dust particles & water droplets are forced together in a process called impingement to collect the dust.

The quality brands Riley Surface World frequently stocks include Carter Environmental to Climavent.

Fume Extraction Fans & Scrubbers

Extraction of odours, chemical and hazardous fumes from processes such as chemical process lines, blow-off systems, welding, drying of inks and paint, paint booths or mist and vapour from industrial parts washers or other wet processes is critical for a safe environment.

A fume extraction system uses a fan inducing a negative draft to pull fumes and dust particles into a contained filtration system. Fans are often constructed from chemical resistant materials such as PVC/GRP and Polypropylene for situations where chemical fumes are being extracted.

Fume scrubbers act to filter and neutralise fumes. There are various ways this can be achieved depending on the fumes involved. This might be using water/liquids to absorb chemicals or passing fumes through materials like carbon filters.
