4.2 ATEX products
All versions of TAV 50 are marked with the CE label.
Depending on the model and purpose of use, some
TAV 50 also have the EX symbol and category mark-
ing. All TAV 50 marked with the EX symbol are cat-
egory 3D equipment according to directive 2014/34/
EU. This means that models with the EX symbol may
be placed in areas classified as zone 22 according to
directive 1999/92/EC.
The manually operated TAV 50 MA is not marked with
the EX symbol as manually operated equipment does
NOT fall under the scope of the directive 2014/34/EU.
Even if the TAV 50 MA does not have the EX marking,
it is highly suitable for use in areas classified as zone
22 and share the same high level of protection as the
TAV 50 with EX marking.
NOTE!
TAV 50 MV-W and TAV 50 MV 24 V AC/DC does
not have the EX marking and may not be in-
stalled in classified areas.
4.3 Category limit
The function of the TAV 50 is to be a part of an extrac-
tion piping system. Even if the TAV 50 with EX symbol
is category 3D equipment for use in zone 22 (TAV 50
exterior), it can be used with a piping system intern-
ally classified as zone 20 or 21. As there is no intern-
al ignition source inside the TAV 50, it is to be con-
sidered as simple piping and does not fall under the
scope of the directive 2014/34/EU.
4.4 Permitted materials
The TAV 50 is only intended to be a part of an ex-
traction system transporting dust with the following
properties: MIE (Minimum Ignition Energy) > 3 mJ and
MIT (Minimum Ignition Temperature) > 205°C. Do not
extract items that may cause ignition or blocking.
