GENERAL DESCRIPTION
6.1
SFE and HFE for industrial and welding fume extraction
These electrostatic air cleaners filter fumes, mists, smoke and dust particles
from many industrial processes at a high efficiency. Normally these particles
remain in the area. Some of these industrial processes are:
A welding and grinding of metals and synthetic materials
B milling, rotating and piercing of metals and synthetic materials
C scouring and polishing of metals and synthetic materials
D filling with powder and/or volatile materials
6.1.1 Modes of extraction of the polluted air
•
SFE: extraction arm or ducting system
•
HFE: extraction grid
6.2
SFE in kitchen extraction applications
This electrostatic air cleaner can remove, at a high efficiency, small grease
particles that pass the grease filters. The SFE is designed to be installed in the
extraction ducting of a commercial kitchen downstream of the extraction
hood.
6.3
Oil drainer
It is possible to install an oil drainer in applications for welding of oil-treated
steel, oil mist extraction or kitchen fume extraction in order to draw off
superfluous liquids from the oil collector.
6.4 Operation
The extracted contaminated air passes the pre filter (fig. 2A) that takes out all
larger particles. The pre filter also ensures a proper distribution of the airflow.
After that, the air passes the ioniser (fig. 2B and 3B). The contaminations in
the air are electrically charged by the high voltage (+10kV). These will then
be deposited on the earthed plates (fig. 2C and 3C) by the collector voltage
(+5kV).
The after filter (fig. 2D) is the last filtration step and it also spreads the airflow.
There are a main switch (fig. 4A), a high-voltage indicator (fig. 4B) and a reset
button (fig. 4C) on the control panel. Please contact your dealer if the
highvoltage indicator is not working.
Regularly check the functioning of the indicator when using the product,
since it indicates that the electrostatic filter is properly charged.
When the product produces a crackling sound, then it could be that the
collector and/or ioniser are too dirty and that both need to be cleaned.
Switch off the product with the main switch (fig. 4A). Wait for at
least 10 seconds prior to opening the door that contains the filtration
section. Subsequently, clean the collector and ionisation sections using
Euromate EFC while adhering to the instructions on the EFC
packaging. Check for touching collector lamellas.
Consult your supplier if the lamellas are bent!
After closing the door of the housing switch on the unit by turning the main
switch (fig. 4A) and press the reset button (fig. 4C).
The distinguishing characteristics of the modular mounting of the ionising
and collector sections are the very high separation efficiency (up to 98% of
particles larger than 0.1 μm), its low air resistance and the userfriendliness
while servicing the separate modules.
Repairs shall only be carried out by Euromate or Euromate authorised staff.
Maintenance contracts are possible.

INSTALLATION
7.1
Installation SFE
Check that the suspension construction is adequate prior to installing the
product. Mount the SFE unit in the ducting system. It can be supported by a
suspension bracket (fig 5A) as well as suspension by screw rods attached to
the top of the SFE unit (fig. 5B). It is also possible to place the unit on the
ground providing sufficient space is allowed to use the drain plug.
Please consult the electrical diagram (separate leaflet, enclosed) when
connecting the air cleaner to the mains. Use suitable rubber or neoprene
cable with at least 4x1,5 mm2 wire area. Beware of possible differences in the
mains power supply.
The air cleaner can be stacked to a maximum of 4 units; the perforations and
protrusions on the housing can be used for this purpose.
7.2
Installation HFE
Check that the suspension construction is adequate prior to installing the
product. Use the profiles (fig. 6E) when mounting the product and attach the
connection rings (fig. 6B), the lock rings (fig. 6C) and the sliding nuts (fig. 6D)
(all supplied with the product) to the profiles. Use a suitable suspension
chain (fig. 6A) in this way of mounting. You can also use the profiles (fig. 6J)
together with screw rods M8 of suitable length. These should be mounted as
illustrated. The following parts are used in this case: screw rod M8 (fig. 6F),
self-locking nut (fig. 6G), lock ring (fig. 6H) and sliding nut (fig. 6I).
Please consult the electrical diagram (separate leaflet, enclosed) when
connecting the air cleaner to the mains. Use suitable rubber or neoprene
cable with at least 4 x 1,5 mm2 wire area. Beware of possible differences in
the mains power supply.
