Field of application
- For use in low vacuum ranges up to 100 mbar (a) or 900 mbar pressure differential.
- Vacuum intake capacity: up to 120 m³/min
Application examples
- Mobile use, e.g. in tanker trucks and suction vehicles
How it works
If vacuum (yellow) occurs between the rotor and the casing, ambient air (blue) enters the blower block via so-called pre-inlet channels as the rotors continue to turn.
The two volume flows subsequently combine and the arising compression heat is dissipated throughout a much larger volume of trapped air.
This approach therefore achieves the same discharge temperatures that are produced by normal blower blocks.
