2 General
OEN series
Area of application
For oil and emulsion mist, glutinous dusts.
Principle of operation
The contaminated air is extracted by the collection unit (hose, hood) and is transported to the filter unit via a pipe or a
flexible hose. In the first chamber of the housing, the oil and cooling lubricant drops are agglomerated and coalesced by
expanding the air (drops combine and grow). During this process, the majority of the drops remain in the expansion
chamber/oil catch tray; the resulting liquid can be drained via a drain valve. The remaining oil and cooling lubricant
particulates are filtered out in the second and third filter levels. The fourth filter level (H13 class particle filter) filters the
ultra-fine particles and contaminants out of the air so that the air is fully non-hazardous and can be circulated back into
the work area or, depending on the application, diverted outdoors through a line.
FPV series
Area of application
Pre-filtering of dry dusts such as those from the milling, drilling, grinding, or laser processing of materials which are not
glutinous and which have not been oiled.
A pre-coating of the filter cartridges with Precofix 200 allows even glutinous substances to be extracted, such as those
produced during laser processing of plastics, wood and rubber.
Principle of operation
The contaminated air is extracted using specially suited collection elements and transported into the filter cartridge pre-
separator by a pipe, a flexible hose or a suction arm. There the dust particles are filtered out by a cleanable filter
cartridge. The filter cartridge can be cleaned by hand using a compressed air gun or using the filter cleaning module, on
which a cleaning interval can be set. The dust particles separated in this manner are collected in a dust collector and can
be disposed of easily and, if required, with little contamination. The cleaned air is then circulated back into the workspace
or, depending on the application, diverted outdoors through a line.
Extraction cabinet
Area of application
The system is intended for the extraction and filtering of substances which arise during work in the cabinet. However no
explosive or flammable substances may be processed, such as solvents, etc. An ATEX-design extraction cabinet must be
ordered for this purpose.
Principle of operation
The work is performed under the extractor hood. A blower is used to extract the dust. The solid substances contained in
the contaminated air remain trapped in the pre-filter and particle filter. The gaseous portion is filtered by the optional
activated carbon (available separately) a then either circulated back into the work area or, depending on the application,
diverted outdoors through a line.
Molecular sieve:
To eliminate or minimise gaseous contaminants or unpleasant odours which can arise from a wide range of production
processes, it is advisable to work with molecular sieves, such as activated carbon. Due to the formation of ultra-fine pores
and capillary systems, the surface measures up to 1,500 m² per gram of activated carbon. This produces an excellent
adsorption efficiency and a large storage capacity, which leads to long service lives.
