Part Explanation
II: Equipment group (non mining equipment).
h: The letter ”h” as specied in EN ISO 80079-36
IIIC: Equipment of Group III is intended for use in places with an explosive dust atmos-
phere other than mines susceptible to redamp.
Equipment of Group III is subdivided according to the nature of the explosive dust
atmosphere for which it is intended.
Group III subdivisions:
• IIIA: suitable for combustible yings;
• IIIB: suitable for combustible yings and non-conductive dust;
• IIIC: suitable for combustible yings, non-conductive dust and conductive dust.
T130ºC The maximum surface temperature in degrees Celsius.
Dc: Equipment protection level Dc. Same as old 3D marking.
For explosive atmospheres, caused by mixtures of air and combustible dusts, the
equipment does not contain any eective ignition sources in normal operation.
-10ºC≤Ta≤40ºC Ambient temperature range.
Nederman 19.HB01X Certicate number. If the sign “X” is placed after the certicate number, it indicates
that the equipment is subject to specic conditions for safe use.
Special Conditions for Safe Use "X"
The FlexFilter EX is designed to be a part of a complete extraction system. A complete extraction system usually
includes a vacuum unit, connected piping and a control system as described in this manual. For the FlexFilter EX
to function properly and full necessary safety requirements as stated in the Declaration of Conformity, the com-
plete system must be assessed with regards to applicable safety standards and directives and comply with all
requirements described in this manual. The designer of the system as a whole, must guarantee correct function of
all interacting products or components and ensure that the complete system meets all necessary safety require-
ments.
Type of Protection constructional safety “c”
Technical documentation contains the information required to maintain the product safety.
