Mechanical Booster Pumps (Roots Vacuum Pumps)
RA100
Motor Directly-coupled Mechanical Booster Pumps
Features
- Feature a compact footprint for easy integration into existing systems.
- The wetted surface won’t rust thanks to its aluminum alloy material.
- Because the internal shaft seal is a non-contact type, the maintenance interval is 2 or 3 times longer than the existing type.
- Operator can check two oil level at the same side, one at the oil supply port and the other at the drain port.
- Low noise, and low vibration.
Application
- Semiconductors, FPD
- Thin Film Coating
- Metals, Steel, Industrial Equipment
- Medical, Chemical, Pharmaceutical, Food
- Research and Development
