Road sweeper for cleaning e.g. road, has filter units cleaned with compressed air from compressed air tank in temporary or differential pressure controlled manner by clean gas-side quick-action valve attached in clean-gas chamber

摘要

The sweeper has a filter system integrated into a rough sweeping leveling container, where the system has a number of filter units (5) for cleaning vacuum air flow from particulate matter. The filter units are cleaned with compressed air from a compressed air tank in a temporary or differential pressure controlled manner by a clean gas-side quick-action valve (4) attached in a clean-gas chamber (2).
