Automatically performs maintenance (cleaning and lubrication) of dental handpieces, which are essential for daily practice. Can perform maintenance for up to 4 handpieces at one time. By employing the dual solenoid valves system and a clean-air dedicated conduit, the system can supply clean air without a mix of oil. During the water removal process before lubrication, the system removes the water in the head, which maximises lubrication results and minimises idling period before practice. Oil consumption is reduced by 4 times compared to manual procedure, allowing for faster maintenance with excellent cost savings. Front door can be removed for improved access. Incorporates a built-in oil mist suction mechanism to prevent aerosol diffusion when in use. Compatible with handpieces and cleaning or lubrication products from other manufacturers.
