Purpose and intended use
Since 1997, there is a new division of
hazardous dusts and their assigned vacuum
machines. These are regulated by IEC 60335-
2-69 (world wide) and by EN 60335-2-69
(European wide).
Dust Class M (medium). The dusts
which belong to this class are: dusts
with OEL values
1) > 0.1 mg/m³ as
well as saw dust. The machine is tested in its
entirety by vacuums for this dust class. The
maximum degree of permeability is 0.1% and
the disposal must be low dust.
Dust Class H (high). The dusts which
belong to this class are: dusts with
OEL values
1) , all carcinogenic dusts
and dusts which are mixed with pathogenic
agents. Vacuums for Dust Class H are tested
in their entirety and have a maximum degree
of permeability of 0.005%. The disposal must
be dust free.
These vacuums may be used for
picking up dusts from the Dust
Classes L, M and H as well as ex-
plosive dusts which makes a Series
Type 22 vacuum necessary. Included in these
classes are non-carcinogenic dusts with OEL
values > 0.1 mg/m³ and/or flammable dusts
in Zone 22.
The air flow in safety vacuum systems has to
be strictly controlled to achieve a minimum
flow rate of V
min
= 20 m/s in the suction hose.
