The most common and eပ¸ective method of collecting oil mist / oil smoke is at the source, i.e. directly
at the metalworking machine. This is possible both in the case of completely enclosed machines and
open machines.
In an enclosed machine, sub-atmospheric pressure is created in the space where the machining
operations take place. The oil-laden air is sucked out of the enclosure and conveyed through a duct
to the filter unit. A∀er the air has been filtered, it is returned to the premises or flows further to a heat
exchanger.
