- Dry, contact-free operation without chamber lubricantsThe compression chamber operates without oil or grease. Lubrication is limited to the gearbox and bearings, which are separate from the chamber.
- Integrated bypass valveThe built-in bypass valve enables safe start-up with a backing pump and prevents motor overload at high pressure differences.
- Standard connection layout, version 01Different connection layouts are available in versions 01–04; version 01 is the standard configuration.
- Industrial electric motorThe flange-mounted electric motor complies with DIN EN 60034 and has IP55 protection and class F insulation.
