Lubrina 2 automatically performs maintenance (lubrication and cleaning) of handpieces which are essential for daily practice. Because the lubrication amount and service time suitable for each handpiece are programmed into Lubrina 2, it can automatically perform maintenance of up to four handpieces in a short time. The clean air-blow system implements lubrication and cleaning of the inside of the handpiece thoroughly, and provides stable maintenance without variations by staff which can occur during manual lubrication. Lubrina 2 accepts multiple brands of spray lubricant.
