Oil Rotary Vacuum Pump
VS Series
VS1501 / VS2401
アルバック
VS1501/VS2401 is classified as a single-stage rotary vane type oil vacuum pump.
The water-cooled and forced oil supply system ensures stable pumping performance even under heavy loads.
They are also designed for easy maintenance with a large oil level indicator.
Features
- Water Cooling and Forced Oil Supply System
The oil supply to the cylinder is satisfied even under heavy load operation, and more stable exhaust performance can be obtained than with the differential pressure oiling system. - Adoption of hydraulic oil anti-suck system
When the pump is stopped, the backflow of oil from the oil tank to the suction side can be suppressed. - Maintenance-friendly design
A large oil level gauge is used for easy monitoring of the oil condition, and a maintenance cover is provided for cleaning the oil tank and replacing the exhaust valve.
Applications
- Optical film vapor deposition system
- Thin film vapor deposition system for reflector
- Evaporation system for decorative moldings
- Evaporation Roll Coater systems
- In-line sputtering systems
- Vacuum Heat treatment furnace systems
- Vacuum Freeze-drying system
- Vacuum Leak testers
- Space chambers
