in accordance with the
dust class ‘L’ as per EN 60335-2-69.
In order to protect the health of persons
working in a dental laboratory, the law re-
quires that specialised dust extractors must
be used.
National regulations state the MAK value
- maximum concentration of suspended
particles in the air.
Find out about the legal national threshold
value and the type of dust generated in
your laboratory.
