Overview
Roots screw units combine a Roots booster with a screw backing pump to improve pumping speed and reach deeper vacuum levels than a single backing pump alone.
Typical applications
- Vacuum drying
- Vacuum metallurgy
- Chemical recovery systems
- Pharmaceutical and fine chemical processes
- High-throughput evacuation
Key features
- Booster stage increases effective pumping speed
- Dry backing pump supports cleaner operation
- Packaged configuration simplifies installation
- Controls and protection logic can be integrated for stable operation
