Information
Description
The AX-65 is an air cooled oil diffusion pump designed for bench top and small scale applications. The air cooled finned boiler provides high pumping speed and great performance without the need for a chiller. This makes the AX-65 a cost effective yet high performance oil diffusion pump.
Features
- High performance specifications means higher, cleaner vacuum levels
- Fluid-level sight glass provides quick indication of pump fluid status at all times
- The wide range of available pump configuration and flange combinations optimizes pump performance and fit for your application
- Compact design makes integration into space-limited equipment easy
- Full thermal protection guards against all over-temperature conditions
- “Pump-ready” thermal switch sends a signal when pump is operational
- Finned, vertical boiler promotes stable pumping, especially of light gases
- Three-stage fractionating jet with ejector stage purifies pumping fluid, giving higher fore pressure tolerance
