Key features
Why the Dry Screw Vacuum Pump
- Oil-free vacuum – suitable for clean processes.
- Low maintenance compared with oil-sealed pumps.
- Good energy efficiency for many industrial applications.
- Continuous operation capability.
- Can handle certain corrosive, solvent-laden, and particulate-containing gases, depending on pump design.
- Good chemical resistance when appropriate materials/coatings are used.
