PRI-SAVER Option
Optional vacuum source that saves water and energy
Why should you add the PRI-SAVER™ option?
HOW DOES THE PRI-Saver SAVE WATER?
Because the system decreases water consumption by up to 97% compared to a water ejector vacuum system.
HOW DOES PRI-Saver SAVE ENERGY?
- Operates on only 110 volts.
- Built into the sterilizer – doesn’t take up space in the service area.
- Notably reduces condensation inside the chamber.
- Reduces ambient noise compared to vacuum pump.
- Minimizes cycle times.
- Solves low inlet pressure, significantly improving the sterilizer’s performance.
- Optional vacuum source that saves water and energy.
