Description
The particle filter box, type FKU for installation of filter cells with
rubber seal has been particularly developed for use in clean-
rooms required by the pharmaceutical, electronic, precision me-
chanical and optical industries in hospitals and laboratories. The
integrated particle filter (to DIN EN 1822) removes particles, ra-
dioactive dust, mist, bacteria, viruses, etc., from the supply or
return air. This ensures that the incoming and outgoing air flows
are extremely clean and germ-free.
The filter cell along with the rubber seal is mounted in the box
by the filter pressure device such that the rubber seal is pressed
in at the filter cell.
The filter box type FKU consists of electrolytically galvanised
sheet steel painted to RAL 9010 (white) with a round connection
spigot for hose connection while the type FKU-Q-... has a rec-
tangular pipe with connection flange. A filter pressure device in
the filter box ensures a safe seal. As a standard feature, a differ-
ential pressure and aerosol monitoring device (-D1) is integrat-
ed into the particle filter box.
Optionally, the particle filter boxes (except type FKU-Q-...) are
additionally equipped with a shut-off damper sealing air-tight.
With the type FKU-H-...-M001-..., this shut-off damper can be
adjusted manually from below after the air diffuser is removed.
The actuation of the FKU-...-Exxx-... with electrical actuator
takes place via an actuator OPEN/CLOSED 24 V with or without
spring return.
Leakage at closed damper blade according to DIN EN 1751,
class 4, at a duct pressure of up to 1000 Pa.
Attention:
We would like to point out that we supply the filter boxes with
integrated spacers for fitting the filter clamps and the diffuser
assembly pole brace. This makes it possible to fit the diffuser
without additional expense, even when the filter has not yet been
inserted into the filter box.
The assembly of the air diffusers is effected via magnetic fasten-
ing. This allows the air diffusers to be easily taken off for filter
replacement and decontamination without requiring tools. The
following ceiling diffusers in supply and return air models are
suitable to be fitted to the particle filter box type FKU:
FDQJ and FPIL. Magnetic fastening is generally not possible for
FPIL and for diffusers made of aluminium and stainless steel.
These diffusers are mounted via central fastening (-VM).
If required, the suitable particle filters can be included in the de-
livery.

(for safe sealing)
without seal leakage monitoring system
with seal leakage monitoring system
Leakage seal monitoring test for terminal filters from H 13
through leakage test according to DIN EN ISO 14644 and VDI

The filter boxes in stainless steel design 1.4301 are
delivered together with the diffuser FDQJ made of stainless
steel. FPIL is not available in connection with particle filter boxes
made of stainless steel.

Installation and maintenance
Attention:
Please note that the O-rings (seals) of the bulkhead stuffing box
may dry out over the months. Once the O-rings have dried out,
the hoses can only be inserted, applying higher force. A com-
mon method of reoiling these bulkhead stuffing boxes is to im-
pregnate a cloth with a universal oil, for example from Ballistol,
and wipe it across the hose, before inserting it. This small
amount is sufficient to make the bulkhead stuffing boxes run-
ning smoothly again.
Installation situation
Attention:
In case of installation above the ceiling, you have to specify
the thickness of the ceiling "s".
Shipping brace
Attention! Before the particle filter unit can be inserted, the
shipping brace clamped by means of the filter clamps must be
removed!

Installation description
Loosen filter clamps (pos. 4) and remove them along with ship-
ping brace. Press the particle filter unit (pos. 6) with the sealing
rubber (see page 3) pointing upwards into the filter housing
(pos. 7) Take care that the filter material is not irreparably dam-
aged. The filter unit can be easily locked using two diagonal filter
clamps (pos. 1 and 3). Next, the VM pole brace (pos. 5, for -VM
only) must be inserted and fastened using the other two filter
clamps (pos. 2 and 4). Care must be taken that the filter clamps
are at first tightened only slightly cross-wise (e.g. in the se-
quence filter clamps 1, 3, 2, 4). After tightening the filter clamps
slightly, they can be tightened properly, again cross-wise and
evenly until the filter unit has a tight fit. Make sure that the filter
clamps are tightened to 4 Nm maximum.
If required, a seal leakage test can be carried out before mount-
ing the air diffusers.
Dismounting
In case of concealed mounting (-VM), unscrew the air diffuser
(in case of magnetic fastening (-MB), insert your hands into the
air diffusor slots and remove the unit). Loosen the filter clamps,
remove the VM pole brace. Take out the particle filter units
downwards.
Attention:
The particle filter cell may fall out of the filter housing when the
filter clamps are removed!
Maintenance
In addition to keeping machines and equipment clean, the main-
tenance of the filters is especially important. A constant control
of the filters is as essential as changing them when the maxi-
mum allowed particle absorption has been reached. The inspec-
tion must take place at short enough intervals to allow faults that
have occurred or become apparent to be eliminated in time. The
necessary intervals are set depending on the local conditions.
The measured variable for the particle intake of the filter is the
pressure difference. This is why a differential pressure measur-
ing device must be attached to each filter stage to monitor its
operating condition. Periodical repetitions of the seal leakage
test should be ordered at regular intervals (at least once a year)
by the operator/owner.
The filter is changed upon reaching the final resistance, which is
set in advance when designing the ventilator capacity of the ven-
tilation system. The final resistance is normally twice the start-
ing resistance.
