Variair Unit 100% Oil Free Screw Vacuum Pumps
| Dry operation | Sound enclosure standard |
| 2.1 speed regulation | Variable speed controlled |
| Direct drive – No drive transmission | Can be used in a Central System |
Driven directly by an integrated frequency inverter, these pumps no longer require any drive transmission. The area in which the units work is 100% oil-free. The integrated speed governor optimises the use of energy by matching delivery to actual demand. This creates high efficiency levels and minimises energy consumption. Suction air remains pulsation-free all of the time.
Various accessories, such as intake filter, non-return valve, sound absorbers as well as the air delivery and discharge system, are integrated in the completely soundproof cover structure.
