<p>The sterilization unit is designed for installation upstream of dental surgery apparatus, and comprises a set of mechanical filters (2) located in series on the compressed air supply line (12) to the apparatus, at least one of which guaranteeing low permeability and ensuring absolute filtration of pathogenic particle sizes, and a further set of filters (3) on the water supply line (11) similar in all respects to the air filters; the option also exists of treating the water supply with at least one ultraviolet device (3), instead of filters, in which case the supply line (11) will be fashioned in a material transparent to ultraviolet radiation so that the unsterilized water can be fully exposed to the emitted rays.</p> |
