xplosion-proof extraction arms are designed
for extraction the dust particles and gases arising during technological processes, whereby, (de-
pending on the local and operational conditions)
exists the occurrence of explosive atmos-
phere
, i.e. a mixture of flammable substances
– in a form of dust particles and gases with the
air, in atmospheric conditions, in case of which (after the ingnition) the burning mass expands
within the whole rest of the not burnt mixture.
Do not apply the extraction arms for corrosive aggressive atmospheres and for environ-
ments containing viscous dusts
.
