Atlas Copco Vacuum Technique

With the new oil-free DSS scroll vacuum pump, Atlas Copco
is expanding its range of dry industrial pumps. The robust, low-wear pump is particularly
suitable for vacuum generation in the rough vacuum range. A key feature of the
innovation is its simple and effective operating principle for gas handling. Inside the
pump there are two intermeshing, spiral-shaped screws made of aluminium. One spiral
screw is fixed, while the second one rotates to compress the gas inclusions.
Lower life cycle costs
The ergonomic vacuum pump is also characterized by low energy consumption, lower
life cycle costs and user-friendly operation. Due to the dry running of the pump, no oil
changes are necessary; there is also no need to replace the exhaust filters. Therefore the
overall maintenance requirements are relatively low. The reduced service and
maintenance costs can also be attributed to the fact that the removable front cover
simplifies access to the pump interior of the DSS scroll vacuum pump.
Predestined for pharmaceutical and food applications
Equipped with these properties and high-quality materials, the new development is
particularly suitable for applications in the pharmaceutical industry as well as in food
packaging and processing. In these and other industries, the pump will provide a stable
vacuum at an atmospheric pressure of up to 1 mbar and maximum productivity at low to
medium flow rates.

According to TÜV Rheinland "completely oil-free
"Another important feature of the DSS scroll vacuum pump is its complete freedom from
oil. It does not use any oil for sealing or cooling, so there is no risk of oil contamination,"
explains Alexander Frerichs, the responsible Atlas Copco Product Manager. To verify
and prove this, TÜV Rheinland has carried out extensive measurements of the aerosol oil
content in 2019. "No traces of oil whatsoever could be detected in the exhaust air stream,
which is a maximum of cleanliness and safety for the production environment and
people," emphasizes Alexander Frerichs. Based on the TÜV results, Atlas Copco's new
DSS scroll vacuum pump has been classified and certified in the top "Class 0".
