Contaminated air is sucked into the inlet in the bottom section of the assembled units and passes
through an Absolent filter where most of the oil particles are arrested. Before the filter becomes sa
-
turated with oil, the oil is drained down to the bottom of the unit that serves as a collection vessel.
The oil is then conveyed back to the machine, to a receptacle or to a central purification system.
The air passes on through another Absolent filter, where any remaining larger particles are ar
-
rested (

and higher). The air is then sucked through a H13 HEPA, which makes it so clean
that it usually can be returned directly to the premises.
5.6 Installation
1.
Place the filter unit at its point of destination and bold it to the
floor.
2.
Open the service door and check that the filter cassettes are
secured. The filter cassettes are properly secured when the
re-
tainer arms point upwards. If a filter cassette has become loose
during the transport, secure it and close the service door. (How
to secure: see 12.3)
.
3. Connect the drainage. Connect a liquid trap to the drainage
(see fig 1). It is important that air is not sucked backward th
-
rough the drainage so it blocks the return oil. Instead of a liquid
trap, it is possible to connect a hose that empties under the
surface of liquid in an open bucket or to an airtight receptacle.
For available liquid traps, see ”13 - Accessories”.
4. Connect the suction pipe with a control damper. When using a
branch pipe the recommended connection is a 30° elbow, as
this gives a low pressure drop for the entire installation.
5.
The next step is to connect the filter unit to electricity. For more
information on handling, see 8. ”Electrical connection”.
