Additional instructions Concerning explosion
protection according to Guideline 94/9/EG
 contains instructions for the unit’s
transportation, installation, start-up, operation,
shut-down, storage, maintenance and
disposal,
 must have been read and properly understood
by operating and maintenance staff before
beginning any work with or on the unit.
 must be complied with and
 must be at hand where the unit is installed.
Operating and maintenance personnel
Operating and maintenance personnel for G-BH1
units must be trained and authorised for the work
to be carried out.
Work on electrical installations may only be
carried out by an electrics specialist.
An electrics specialist is someone who can
evaluate and identify potential risks for the
assigned task as a result of their technical
training, knowledge and experience as well as
knowledge about relevant regulations.
G-BH1 units
 create a vacuum or overpressure.
 are used to extract, deliver and compress the
following gases / vapours:
− all dry and damp gases which are not
explosive, combustible, aggressive or
poisonous,
−
air or air-vapour mixtures.
− in the case of aggressive or poisonous
gases / vapours, please consult the
manufacturer.
− the gases / vapours must be free of solid
matter.
Small quantities of light suspended matter
or liquids can be conveyed along too.
 are suitable for a deep vacuum range.
 are equipped with RL 94/9/EG three-phase
drive motors. For more detailed information
please consult the motor manufacturer’s
accompanying operating instructions.
 are available in two constructions:
− Construction for normal requirements
− Construction for higher corrosion-resistance
and hygiene requirements (only 2BV2 070.
2BV2 071 and 2BV5 ..)
 are designed for industrial plants.
 are designed for continuous operation.
When operating the units, the limiting values
listed in chapter 3 operating manual
610.44440.40.000 "Technical Data" are to be
complied with.
Scope of application for units according to
Guideline 94/9/EG
Inside area of explosion prevention design
G-BH1 units are suitable for conveying
gases/vapours where a potentially explosive
atmosphere is occasionally expected to be
present.
This specification includes category 2G for the
internal space of the units.
If the specified maximum temperatures are
complied with, the units are suitable for
temperature class T4.
Surrounding area
When rating the device category, both the place
where it is installed and its internal space must
be taken into consideration.
Installing G-BH1 units for category 2G is allowed
for areas where potentially explosive gases /
vapours are expected to occur occasionally.
