Oil service in record timeW&H has succeeded in decreasing the maintenance process to a record time of just 10 seconds

An innovative system

The oil is nebulized before being blasted through the instrument at high pressure. This removes soiling from the inside of the instrument even more effectively. Thanks to the fine mist, every single part of the gear is wetted without having to set the gear parts into motion. All aerosols are removed from the process chambers through active suction and an integrated HEPA filter.
