Dust Extraction Equipment Classes Explained



< 0.005% Dusts with maximum allowable concentrations (MAC) < 0.1 mg/m³

L Class is awarded to entry level extractors and is suitable for use with less hazardous dusts such as those generated from soft woods and gypsum in plasterboard. The filter is capable of extracting 99% of particles so is not suited for use with more hazardous dusts such as those from sanding paint, fibreglass or hardwood.

Recommended for: Soft woods | Gypsum | Corian

  • Very quiet at 67dB(A)


< 0.1% Dusts with maximum allowable concentrations (MAC) ≥ 0.1 mg/m³

M Class extractors are 99.9% efficient, meaning that only 0.1% particles might not be captured through the filters. M Class is the UK legal minimum as specified by the HSE for certain industries. Dust extractors rated as M Class will not necessarily offer greater filtration or suction performance but are generally better suited to trade users and will come fitted with safety features such as an alarm to notify the user when the filter is becoming clogged.

For Safely Working With Explosive Dusts

ATEX extractors are designed to handle potentially explosive dusts. Through the use of wet filters (and other methods), explosive dusts can be neutralised and removed safely.

With recent innovations in composite materials new binding resins are being introduced, some of which have explosive characteristics. This has led to an increased demand for ATEX extractors in our industry.
