Independent supply system The SANASPRAY disinfection system consists of a pressurised 2-litre container that allows distilled water (with added sanitising fluids if required) to be used for the cup and all the dentists module instrument sprays and the assistants syringe. The system thus allows water to be fed independently from the mains supply, especially useful where dental units are installed in areas where the water supply is particularly hard. Convenient and versatile The tank is placed outside the unit body, making it easily accessible to the assistant. A second, optional, tank is provided for rapid circuit sanitisation using the BIOSTER S system. The use of Peroxy Ag+ disinfectant is recommended on account of its proven effectiveness. The SANASPRAY hygiene system is available as an optional on the S280TRC, S320TR, S220TR and S300 dental units.
