Booster Pump for Sterisil Water Systems – for builds with <65 PSI source pressure. A booster pump is recommended when the incoming water pressure is less than 65 PSI, or there is an elevation change between the G4 and the dental operatories/dispensing faucets. For direct feed applications, if the chair furthest from the system is more than 50 feet, a booster pump may be needed to maintain adequate water pressure at the handpiece. Works with: • Sterisil® AC+ Autoclave Water System • Sterisil® G4 Autoclave and Dental Water System • Sterisil® G5 Intelligent Autoclave & Dental Water Purification and Treatment System Space Requirements: 7″H x 4″ D
