5.1 Intended use
The negative pressure unit Compact 25.000 was built for the filtration of non-condensing
asbestos contaminated air, in temperature range up +45 °C, with external exhaust for the
air. During asbestos sanitation works within closed rooms, it must be avoided that
asbestos fibres leave the sanitation area and in this way endanger humans and the
environment. For these reasons, the sanitation areas (also called dirty area) have to be
separated from the clean area with the help of a negative pressure unit and kept under
dynamic negative pressure.
An integrated filtering system establishes the conditions that the asbestos concentration
in the exhausted air does not exceed max. 1000f/m³. The exhausted air is blown in the
open air.
The device is not appropriate for the filtration of flammable gas or dust.
