Local exhaust ventilation – tackling potent VOCs head on

Case study - fume extraction

Their Challenge

Our client is a consultant mechanical engineer seeking a solution on behalf of their client. They needed to find a suitable local exhaust ventilation (LEV) system to keep their clients’ workers safe, by safely extracting a range of volatile organic compounds (VOCs) that were produced in their work processes, including:

  • Dimethylsulfoxide (DMSO)

  • Dimethylformamide

  • Ethyl Acetate

  • Maleic Anhydride (MAH)

  • Styrene

  • Acetone

  • Methyl-Ethyl-Ketone

Our Solution

We recommended a customised version of Aerservices’ ICAF. This heavy-duty, mobile filtered fume extractor is particularly suited to industry use, and is designed for high concentrations of fumes and particulate.

Usually, the ICAF comes standard with a set of 5 multi-stage filters, including a total of 24kg of active carbon. The four sides of the unit’s filter box each contain five filter plates, giving a total of 20 filters.

For this client, we replaced the standard filters with specialised Aerservices filters, to only include two filters each side (a total of 8 filters). This new configuration was made up of four flat filters and four special active carbon filters (at 23.1 kg each). Yep, that’s over 92kg of active carbon filters!

We also recommended two ARMOTECH externally supported aluminium articulated arms, Ø125mm by 3 metre long, allowing for use by two workers side by side.

Their Satisfaction

Our client said their client was very satisfied with the ICAF unit we supplied, as it performed exactly the outcome they needed for their ventilation requirements.

They are now currently looking for purchasing additional units.
