Description
The FKF particle filter box with fluid seal on the filter cell has
been specially developed for use in cleanrooms as required by
the pharmaceutical, electronic, precision mechanical and optical
industries in hospitals and laboratories. The integrated particle
filter (to DIN EN 1822) removes particles, radioactive dust,
mist, bacteria, viruses, etc., from the supply or return air.
This ensures that the incoming and outgoing air flows are ex-
tremely clean and germ-free.
The fluid is located at the filter cell and pressed into a sealing
device especially developed for this purpose in the filter box
when the filter cell is installed. Owing to the properties of the
fluid, the filter cell can be mounted and dismounted several
times without having to change the fluid.
The filter box, type FKF-... , consists of electrolytically galva-
nised sheet steel painted to RAL 9010 (white) or stainless steel
V2A (1.4301) with a round connection spigot for hose connec-
tion while the type FKF-Q-... has a rectangular spigot with con-
nection flange. A filter pressure device in the filter box ensures
a safe seal. As a standard feature, a differential pressure and
aerosol monitoring device is integrated in the particle filter
box.
Optionally, the particle filter boxes FKF-H-... are additionally
equipped with a shut-off damper sealing air-tight. This shut-off
damper can be adjusted manually from below after the air dif-
fuser is removed. Leakage at closed shut-off damper according
to DIN EN 1751, class 4, at a duct pressure of up to 1000 Pa. An
electric actuator is not available. As an alternative, a SCHAKO
DKA-L in ATEX version can be used outside the filter box.
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 air 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 air diffusers in supply and return air models are
suitable to be fitted to the particle filter box type FKF: FDQJ,
FPIL, FDAV. Magnetic fastening is generally not possible for
FPIL and FDAV and for air diffusers made of aluminium and
stainless steel. These air diffusers are mounted via central fas-
tening (-VM).
If required, the suitable particle filters can be included in the de-
livery.
Sealing on the particle filter
The filter boxes in stainless steel design 1.4301 are
delivered together with the air diffuser FDQJ made of stainless
steel. FPIL and FDAV are not available in connection with parti-
cle filter boxes made of stainless steel.
The particle filter box has the following ATEX marking:
This particle filter box meets the regulations of the ATEX direc-
tives and can be used in ventilation systems in areas subject to
explosion hazards.
The particle filter box has been certified for the explosion pro-
tection group II for Zones 1, 2 and 21, 22.
Zones 1 and 2 represent the application range containing gases,
while Zones 21 and 22 represent the application range contain-
ing dusts.
Classification by zone must be established by the system oper-
ator or planner in compliance with current standards.
Note:
In explosion-protected zones, only devices that have an ATEX
approval for this use may be used.
Technical data, information
- The grounding terminals of the particle filter box must be
connected to the equipotential bonding.

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".
Attention! Before the particle filter unit can be inserted, the
shipping brace clamped by means of the filter clamps must be
removed!

Fastening of grounding connection
Detail W
The grounding connection is fastened on the clean air side of the
filter box. 2 M4 riveting nuts are used for fastening.
(Fastening screw on site)
Installation description
Loosen filter clamp (pos. 4) and re-
move it along with shipping brace.
Press the particle filter unit (pos. 6)
with the fluid seal (see detail Z) point-
ing upwards into the filter housing
(pos. 7). Take care that the filter ma-
terial is not irreparably damaged.
The filter unit can be easily locked us-
ing two diagonal filter clamps (pos. 1
and 3). Next, the VM pole brace (pos.
5) is 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 sequence fil-
ter clamps 1, 3, 2, 4). After tightening the filter clamps slightly,
they can be tightened properly, again cross-wise and evenly un-
til the filter unit has a tight fit. Care must be taken that the filter
clamps are tightened to 2 Nm maximum. A buffer prevents the
immersing sword from severing the fluid.
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
and take off the VM pole brace. The particle filter cell can easily
be taken off downwards with an assembly lever. The assembly
lever is led sideways from the filter upwards and then hooked on
the filter top edge. Gently pulling on the assembly lever removes
the filter from the box.
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. Because of this a differential pressure
measure device is attached at every filter step to monitor the op-
erating condition.
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.

Information regarding assembly and commission-
ing
Prior to being installed in the ventilation system, the particle fil-
ter box must be checked for damage. Damaged fire dampers
must not be installed.
The device may only be used in accordance with its designated
use in air ventilation systems for supply air and return air.
Use only approved fastening material for mounting.
No additional parts must be fastened to the particle filter box.
The particle filter box must be connected to the ventilation duct
network in electrically conducting manner.
In order to avoid the risk of static charges, the particle filter box
must be connected to the on-site equipotential bonding on the
grounding connection provided for this purpose.
Make sure that the ventilation systems are not subjected to any
anomalous operating conditions, such as vibrations, pressure
surges or high proportions of solids in the medium.
If required, the electrical connection diagrams can be found in
the respective Schako additional information.
Electrical wiring and commissioning work must be performed
by skilled personnel only.
Information regarding maintenance and inspection
Proper maintenance increases operational safety and the serv-
ice life of the device. This is why the devices should be subjected
to regular inspection.
If inspection dates are prescribed by law, they must be complied
with.
The operating personnel must be informed, prior to starting
maintenance and inspection work.
The personal safety measures must be looked up in the safety
data sheet. Hazard caused by contact or inhaling hazardous sub-
stances must be excluded by taking appropriate safety meas-
ures.
Prior to maintenance or inspection, all system components up-
and downstream of the device must be switched off and secured
against being switched on again.
The following inspection criteria must be observed:
- Visual inspection of the device
- Check the fastening of the device
- Check the grounding connection for tight fit and good contact
- Functional check
- For additional inspections, please refer to the technical docu-
mentation or additional maintenance instructions
