Function
The Vacuum Cleaner sucks dust and dirt from ventilation ducts, which has been re-
moved mechanically or by pressure air before. The section of the ventilation system
that has to be cleaned is sealed from the surroundings and kept at low pressure. This
is necessary to support the cleaning process and to prevent dust from entering into the
surrounding atmosphere. The Vacuum Cleaner is part of the under pressure system.
