6.0 GENERAL DESCRIPTION
6.1 SFE AND HFE FOR 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
6.2 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 high voltage 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 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 lm), its low air resistance and the userfriendliness while servicing the separate modules. Repairs shall only be carried out by authorised staff. Maintenance contracts are possible.
7.0 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 necessary to drill holes on the upper side for this purpose. 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. The position of the contact bridges may need to be changed as well as the connections inside the motor compartment. When connecting, pay attention to the direction of rotation of the motor!
Ensure at all times that the setting of the thermal relay corresponds with the nominal current rating of the motor for the applicable power mains. This rating is given on the motor identification plate.
8.0 MAINTENANCE
If you observe the necessary caution and carry out the simple maintenance and cleaning described below at regular intervals, then any problems will mostly be detected and corrected before they result in a total breakdown of the product. The indicated maintenance intervals can vary depending on the specific working and local conditions.
It is therefore recommended that the product is thoroughly inspected annually in addition to the indicated periodic maintenance. Please contact yoursupplier for this purpose.
TABLE 2. CLEANING TASKS
| Action When | |
| Clean the pre-filter, ioniser, collector and the afterfilter and check for damages | Every 2 weeks to 2 months, depending on the degree of usage / pollution |
| Clean the inside of the product and remove dust / grease from the filter compartment | Every 3 months |
| Clean the outside of the product with a mild detergent | Every 6 months |
| Check the door sealing material Every 12 months | |
8.1 PERIODIC MAINTENANCE
The maintenance activities in the table above can be carried out by the user; other activities are strictly reserved for qualified personnel.
8.2 CLEANING THE SEPERATE PARTS
Clean or replace the filters:
- When damaged
- When the ioniser and/or collector starts to make a crackling sound (indicator starts blinking or stops being lit)
- When the extraction capacity becomes inadequate
It is a matter of experience to determine when the product needs to be cleaned, since the nature and the degree of pollution depend strongly on the particular situation, humidity, intensity of use, etc. Nevertheless, the filters should be cleaned regularly (every 2 weeks up to 2 months).
To remove the filters, switch off the unit by turning the main switch (fig. 4A). Loosen the star knobs and open the door. Remove the pre filter, ioniser, collector and the after filter (in this sequence).
MAINTENANCE
Clean the pre and after filters in hot water (approx. 60^ C) added with a detergent for domestic use. This treatment can be repeated several times. Cleaning with a high-pressure spraying pistol is also possible. Allow for complete drying after cleaning.
Clean the ionizer and collector in hot water (approx. 60°C) to which a 2% EFC solution has been added. Cleaning using a high-pressure spraying pistol is also possible. Check the ionizer during washing for broken ionization wires. These broken wires can simply be replaced. Check the collector during washing for bent lamellas. These can be carefully straightened with a screwdriver. Lamellas in contact with each other can cause short-circuiting. Allow for complete drying after cleaning.
The filters can be put back in place in reversed order.
