Tab. 3-4 Drive fluid requirements
Drive with compressed air
Maximator gas boosters generally do not need a compressed air oiler as they are
treated with special grease during installation. However, after the first time an
oiler is used, the drive fluid should always be oiled. In case a compressed air oiler
is used, the oil must comply with DIN 51524 - ISO VG 32 specifications.
If dry or very dry compressed air is used, a gas booster with FEC option is recom-
mended.
Drive with nitrogen
As standard, all Maximator gas boosters can be operated with nitrogen. This is
equivalent to operation with dry or very dry compressed air.
Drive with other gases
A drive using other gases or gas mixtures (e.g. natural gas) is principally possible.
The gas mixtures used must not be ignitable. The gas mixtures used must not be
chemically unstable. The suitability of the drive fluid must be checked. Special
materials or drive variants must possibly be used (e.g. drive with exhaust air port
line). Maximator will be happy to support you with this.
