GAS-TIGHT BLOWERS FOR
ADDITIVE MANUFACTURING
METHODS
In selective laser melting (SLM)
a stable inert gas atmosphere
must be ensured within the
built chamber of the machine. A
specified temperature range is
also essential. Only under these
conditions can high quality
components be produced. It is
further necessary to remove metal
splash and smoke developing
during the melting process.
At formnext (hall 3.0, stand H
69) Gebr. Becker GmbH will be
presenting two blower types
developed precisely for these
and similar applications. The key
dif-ference to other series is the
gas-tight design which permits
the precise control of the gas
flow as well as the removal of
contamination from the process.
In combi-nation with also gas-
tight heat exchangers from the
programme of Gebr. Becker they
also create the conditions for an
exact temperature control of the
additive manufacturing process.
For plants with a small built
chamber the gas-tight and speed-
controlled VASF side channel
blowers of size
1.50 are ideal (figure 1). They are
of a highly com-pact construction
and can be easily integrated in
the plants, enabling the flow
management of the inert gas in
the closed circuit and low energy
operation as required.
• Vibration Sensors (IEPE + 4-20mA)
• Test & Measurement Sensors
• Hazardous Area Vibration Sensors
• Seismic Sensors
• Hydrophones
• Vector Sensors
• Proximity Probes
• Vibration Switches
For larger plants in additive
manufacturing and the
correspondingly higher volume
flows of inert gas the gas-tight
side channel blower VARIAIR
SV 300 is used. Here too, the
speed-controlled energy-efficient
drive enables the delivery rate
to be adapted to the actual
requirements.
Both blowers are designed for
24/7 industrial operation and
proven worldwide in numerous
demanding applications. Due to
their gas-tight design they are
suitable for the requirements of
additive manufacturing in high-
grade atmospheres.
