Microfilter for AS400micro
DESCRIPTION OF UNIT
The AS400/AS400micro dust extractor is based on a
concept which has been tried and tested for years and
used successfully in many branches. The motor unit
of the AS400/AS400micro is designed for extremely
quiet running and includes a powerful "Turboflo" motor
turbine which is guaranteed to produce exceptionally
high suction. The plaster dust is extracted via a two-
stage filter system. The first stage involves blasting the
plaster dust into a paper dust bag. During the second
stage, the removable fibrous filter traps all dust par-
ticles remaining in the outgoing air. Additionally, in the
AS400micro variant 99.995% of the respirable dusts
which may be produced in combination with sandjets
and zirconium oxide processing systems are filtered
out by an integrated microfilter module. The housing
of the AS400/AS400 micro is made of sturdy steel
plate and coated with long lasting, resistant epoxy resin.
INSTALLATION
After unpacking the unit, please check it immediate-
ly for possible damage incurred during transport.
Should the unit have been damaged during trans-
port, please complain to your supplier immediately.
AS400 VERSION
The AS400 aspirator is suitable for gypsum dusts.
AS400 MICRO VERSION
The AS400micro version has an integral microfilter
module. This high performance filter module retains
up to 99.995% of harmful respirable dusts.
IMPORTANT: When used with zirconium oxide mil-
ling devices and blasting cubicles, the AS400micro
(with three-stage filter system!) provides optimal
protection from zirconium oxide dusts and respi-
rable dusts which conventional filter systems may
release again into the workplace air. The
AS400micro complies with the required guidelines
for the use of aspirators used for zirconium oxide
milling devices and blasting cubicles and thus
provides optimal protection from harmful respirable
dusts.

CONNECTING THE ELECTRICITY SUPPLY
Check the voltage. Check that the voltage quote on
the rating plate on the back of the housing coincides
with your electricity supply.
The dust extractor receives its power from the unit
to which it is connected and is operated via the
ON/OFF switch on this unit. The power cable of the
AS400/AS400micro is fitted with an earthed plug
and should be connected to the connecting cable
supplied with it. The other end of the connecting ca-
ble should be plugged into the back of the unit.
If a different type of unit is used, a connecting cable
with the correct type of plug is required.
CONNECTING THE HOSE
Before connecting the suction hose (1.25 m) supplied
with the unit, the black plastic part on one end of
the hose must be removed. Into the black plastic
part (black plastic nut). The plastic nut on the end of
the hose should then be wound onto the threaded
coupling on the extractor.
SERVICING/REPLACING THE FILTER
Open the catches on the side of the unit and lift the
motor housing upwards. When changing and cleaning
the filters, sufficient inhalation protection is manda-
tory.
1) Replacing the paper filter bag
A paper filter bag should always be used in laborato-
ries as it enables the extractor to be emptied very
easily and neatly. It also enhances the suction. Ensure
that the correct type of filter is fitted (No. 114953).
2) Cleaning the fibrous filter
Lift the fibrous filter carefully and, preferably in open
air, brush it with a household brush until it appears
clean. This should be carried out when replacing the
filter bag to ensure that the extractor performs opti-
mally.
3) Replacing the fibrous filter
When replacing the fibrous filter, check that the
washer seals properly and is not damaged. Should it
have been damaged, air may leak in between the
motor housing and dust container and prevent the
extractor performing optimally. Should this occur, re-
place the fibrous filter with a new one (No. 114954).
PLEASE NOTE!
Like all electrical appliances, dust extractors must be
operated carefully. This unit must be serviced regu-
larly to ensure that it runs smoothly. Failure to service
this unit regularly or replace worn components may
