5.1 FUNCTION A•mist10C
Contaminated air is sucked into the inlet on the
side of the assembled unit. For this version of the
A•mist10C unit, the ltering process occurs in one
stage only. There are dierent lter cassettes to suit
dierent applications available. Depending on the
type of the chosen cassette, the constant collecting
eciency varies from 83 up to 93%. Thanks to the
continuous draining of the lter cassette, the unit
can be operated without interruption 24-7. The
returned oil is collected at the bottom of the lter
for recycling.
The air is then extracted through the fan, after
which it is usually clean enough to be returned
directly to the premises.
An electronic manometer indicates when the lter
cassette needs to be washed or replaced. A signal
from the electronic manometer can also be transfe-
rred from the unit to somewhere externally.
5.2 FUNCTION A•mist10C WITH HEPA
Contaminated air is sucked into the inlet on the
side of the assembled unit. For this version of the
A•mist10C unit, the ltering process occurs in two
stages. Thanks to the continuous draining of the
Absolent lter cassettes, the unit can be operated
without interruption 24-7. The returned oil is col-
lected at the bottom of the lter for recycling.
The air is then extracted through the fan, after
which it is ltered once more in an HEPA H13 cas-
sette. The HEPA cassette oers a guaranteed and
consistent collecting eciency of 99.99% arresting
mpps (most penetrating particles approx. 0.14 µm.
The air is now usually clean enough to be returned
directly to the premises.
An electronic manometer indicates when the lter
cassette needs to be washed or replaced. A signal
from the electronic manometer can also be transfe-
rred from the unit to somewhere externally.

9.2 SERVICE SCHEDULE
9.1 GENERAL
Preventive maintenance and regular service extend the life span and ensure that the lter unit
maintains its performance.
To facilitate inspection of the lter cassette status, Absolent supplies an electronic pressure mo-
nitor, A•monitor, as standard equipment. It is positioned on the front of the lter unit as shown
below:
More information about the electronic pressure monitor can be
found in chapter 10.
1) The lter cassettes should be checked once a month during the rst six months that the lter unit is in use. The service interval can
then be adapted accordingly, but inspection intervals must be no longer than six months. Note that when the yellow LED is lit, the
inspection interval must take place more frequently as the pressure drop now increases quicker.
2) The bottom section and drainage should be checked once a month during the rst six months the lter unit is in use. The service in-
terval can then be adapted accordingly.

ELECTRONIC PRESSURE MONITOR
10
10.1 FUNCTION DESCRIPTION
An electronic pressure manometer A•monitor is supplied as standard along with all A•mist10C lter
units.
The pressure monitor is delivered factory preset and contains the following features:
OPTICAL DISPLAY OVER EACH FILTER STAGE
The present pressure drop over each lter stage is monitored:
Filter 1 - Filterstage 1, ie S3B1/595 alt. S3B3/595. See also 11.2.
Filter 2 - Filterstage 2, ie HEPA Filter. See also 11.2
LED INDICATION
A green LED lamp is lit as long as the lter cassette is working within the preset pressure
range. When the yellow lamp is lit, call your service contact to replace or wash the lter
stage (only valid for lter stage 1). When the red LED lamp is lit, the pressure drop is too
high for the lter unit.
HOUR COUNTER DEVICE
An hour-counter device is also included in our standard equipment.
It measures and monitors the operation time in hours for the lter unit.
PLEASE NOTE!
If a lter stage is used even though the red LED-lamp is lit, the lter unit gives a reduced air volume. Note
however, that the lter unit will not be damaged when operated with a clogged lter stage.
Handling during service is described under“Changing the lter”.

11.5 WORN OUT FILTER CASSETTES
When the lter cassette is worn out it has to be taken care of in an environmental-friendly way.
The sheet metal casing and the aluminum separators can be recycled.
Clean ltermedia can be sent to disposal facilities, but when it contains oil and particles from the
process, local regulations for disposal or incineration need to be followed.
If the oil is washed from the cassette, it can usually be sent for landll.
11.6 TO CLEAN FILTER CASSETTES
Filter stage 1 can be washed several times*). Wash with water-based degreasing agent in a
chamber washer (pict. A), max. permissible water temperature: 90°C.
After washing, the lter must be left to dry until it no longer drips before it can be used again
(Figure D). The lter continues to dry in the lter unit.
The Absolute lter (HEPA) is not washable and must be replaced when the pressure drop exceeds
the ”service required”level.
If you do not have a chamber washer, you can place the lter cassette in a tub lled with
water mixed with a water-based degreasing agent for 4-8 hours. Remove the cassette from the
tub and allow the lter cassette to nish dripping before you ush it clean with a high-pressure
washer.
Be careful not to damage the separators when you spray them under high pressure. The result of
this cleaning method is doubtful and should therefore be tested from case to case.
Check that the sealing strip is undamaged before you ret the lter cassette. The sealing strip
must face upward.
*) Depending on the type of impurities it is exposed to, the useful life of the lter may reduce after wasching, when
compared with a new lter.

US_CA/ A•mist_10C/UM2239-1
12.7 SPRAY SYSTEM
If the extracted particles are ”too dry” or if they
contain liquid particles with excessive viscosity
(sluggish), this drastically reduces the self-cleaning
capability and useful life of the lter unit.
To increase the liquid content in the extracted
particles and/or reduce the viscosity, small liquid
droplets are sprayed from a nozzle into the air.
The liquid added must be able to dissolve the
impurities separated in the lter. Water is used for
emulsions. The spray nozzle is mounted in the inlet
duct of the lter unit.
The spray nozzle is controlled by a time relay with
adjustable pause and spray period. For instructions
on safety, installation and maintenance, see the
separate instructions for use.

12.6 EXTENSION HOOD FOR AFTER-ASSEMBLY OF
HEPA
If the lter unit has been delivered without a HEPA
lter, it still can easily be retrotted later on.
A kit consisting of HEPA hood and HEPA cassette can
be ordered separately.

Malfunction Possible cause Action
Low capacity
(air ow)
The fan rotates in the wrong direc-
tion.
Check the fan’s direction of rotation (only
skilled personnel). See heading 13
With speed (rpm) regulation: The fan
speed (rpm) is set too low.
Check the fan speed (rpm) - (only skilled
personnel).
Too high pressure drop over one or
more lter cassettes.
Check the pressure drop. If any of the yellow
or red LED lamps are lit on the electronic
manometer, the lter cassette to which the
lamp relates needs to be replaced.
High pressure drop in the duct
system.
Check and possibly change the duct system.
Adjustable damper is closed or
incorrectly adjusted.
Check and possibly adjust the damper on
the suction pipe between the machine and
lter.
The ducts are not sealed or dirty. Check that there is no leakage from the suc-
tion pipe between the machine and lter.
Check that the ducting doesn’t contain dirt.
Abnormally short repla-
cement interval for the
HEPA lter:
An incorrectly positioned or dam-
aged sealing strip can result in
leakage past lter stage 1, resulting
in unltrated air reaching the HEPA
lter.
Check that lter stages 1 and 2 are tted
with the seal pointing upwards. Also check
that the sealing strip is undamaged.
Cassettes that are not secured can
result in air leakage past the lter
cassettes. Unltered air will then
reached the HEPA lter.
Check that lter stages 1 and 2 are secured
against the sealing frame correctly.
The lter cassette in stage 1 is not
optimised for the application in
question.
Check with Absolent that the correct lter
cassette is being used in lter stage 1 for the
application in question.
Abnormally short service
interval for the lter
stage 1:
The lter cassette in stage 1 is not
optimised for the application in
question.
Check with Absolent that the correct lter
cassette is used in lter stage 1 for the appli-
cation in question.
The lter cassettes have become
clogged on account of high viscosity
in the oil mist, which gives insu-
cient drainage.
If emulsions are used, lter clogging may
be due to the lter running when produc-
tion has stopped, which dries out the lter
cassette (water evaporates). Consequently,
switch o the lter unit when not in use. If
the uid in the process has a high viscosity,
it is necessary to apply uid with a spray
system (heading 12.9).
The lter cassettes have become
clogged.
Check that chips have not been drawn down
with the air into the lter unit. The problem
with chips can be solved by calibrating the
air ow or coarse ltering before the lter
unit. Also check that sticky particles have
not clogged lter stage no. 1 (for example, in
foundry applications). Contact Absolent for
appropriate measures.

Absolent always take full responsibility that the delivered product fulls the function and life time that
was guaranteed when purchased. This warranty is however only valid if the product is in its original con-
guration and only when original spare parts have been used when servicing or repairing the lter unit.
Some examples on why orignal parts are so important are shown below:
1. FAN MOTOR
In order to cope with the special assembly conguration in an Absolent unit the original motor is
supplied with special bearings and a bearing locking device.
Using the ”wrong” type of motor will increase the risk of breakdown or failure.
2. FILTER CASSETTES
The Absolent oil mist lter depends on the multi-stage ltration technology. The unit contains one
or two lter cassettes. In order to reach the optimum ltration eciency and the longest possible
life time, the lter cassettes have been carefully balanced against each other.
If one or several of these cassettes are replaced by a lter cassette this balance is destroyed and
the consequence is decreased collecting eciency and shortened life time for all lter stages.

CHECKING THE FAN’S DIRECTION OF ROTATION
14
Make sure that the fan impeller rotates in the correct direction. Since you are unable to see the impeller
direction due to the construction, you have to use the electronic manometer instead.
If the pressure drop over the rst lter is < 50 Pa, then transpose the two phase leads and restart the fan.
Check the lter pressure drop again, to see if it is >100 Pa. The direction of rotation is then correct.
WARNING - DANGEROUS VOLTAGE
All electrical work must be carried out by qualied electricians.
