dust extractor

Whether you are working on a commercial or residential job site, dust poses a significant health risk. Especially working with large quantities of certain materials.

Dust extraction is important and not just in keeping the work area clean and tidy. Small dust particles can penetrate deep into the lung tissue and become far more harmful to your airways.

Having the right dust extractor for the job and being meticulous in your cleaning is highly advised, alongside wearing the proper protective gear whilst working.

Different classes of extraction

The first aspect to consider is the class of the dust extractor.

In line with health and safety standards, there are different classes of dust extraction ranked by the percentage of extracted dust to pass out of the filter. The main classes are:

  • Class L – An extractor must not allow more than 1% of extracted dust to pass out of the filter to a “maximum allowable concentration” (MAK value) greater than 1 mg/m^3
  • Class M – An extractor must not allow more than 0.1% of extracted dust to pass out of the filter to a “maximum allowable concentration” (MAK value) greater than 0.1 mg/m^3
  • Class H – Must not allow more than 0.1% (can be as low as 0.005%) of extracted dust to pass out of the filter to a “maximum allowable concentration” (MAK value) less than 0.1 mg/ m^3

Class L extractors are suitable for most DIY and trade jobs that don’t require a higher performance of dust extraction. Class L dust extractors are a popular choice with our customers.

Class M is specifically for mineral dust, man-made wood based dust, oak and beech woods. They boast better filters, especially ideal for specialist work on residential sites with little or no ventilation.

Class H is used with anything that is a known carcinogen (i.e. asbestos) and is required for more heavy duty applications.

Why Dust Extraction is so important

The adverse effect dust particles can have on your health shouldn’t be ignored. A 2010 study* found that the relative risk of asthma for employees exposed to wood dust is 1.53x higher than among the general population.

The importance of having the correct dust extraction in place on the job site is vital for preventing potential breathing-related health conditions further down the line.
