The TSF fi ltration unit is solely designed for cleaning dry air polluted with dust. The use of this type of fi lter in other applications is not permissible unless the manufacturer has guaranteed that it will operate correctly in that environment. If the TSF is used in environments where the air can contain graphite, lead or chrome, it may be necessary to clean the fi lter unit and replace its fi lter cartridges more frequently.

Warning! The TSF must not be connected to machines whose machining operations involve a risk of explosion or to media that are infl ammable and where there is risk of dust explosions; without fi rst obtaining approval from Absolent.

Performance / Design – TSF4F & TSF4/8-1200TSF4FThe dust-laden air is sucked into the inlet (1) on the side of the fi lter. When the air enters the fi lter chamber, its velocity drops and the heaviest dust particles fall into the dust container (10). The air and lighter particles fl ow further through the four fi lter cartridges (2) where the dust collects. The clean air then fl ows to the integrated fan (4), which discharges the air across an absolute fi lter (3) to outlet (5). At this point, the air is so clean that it can be returned directly to the room. When-ever the pressure drop across the fi lter cartridges (2) exceeds the preset limit value, the valves in the pulse-cleaning air tank (7) are activated and discharge a pulse of compressed air (approx. 4 Bar) from cleaning nozzles (8) (1 nozzle/fi lter cartridge). This reverses the air in the fi lter cartridges (2). The compressed-air pulse jars the dust collected on the surface of the fi lter medium causing it to fall down into the dust container (10).

Whenever the pressure drop across the fi lter cartridges (2) exceeds the preset limit value, cleaning starts (see the TSF4F explanatory sketch) by activating valves for cleaning which discharge compressed air (approx. 4 Bar) from cleaning nozzles (1 nozzle/fi lter cartridge). This reverses the air in the fi lter cartridges (2). The compressed-air pulse jars the dust collected on the surface of the fi lter medium causing it to fall down into the dust container (4)

GB Fault Tracing


1. Check that the fi lter unit has not been damaged in the transport. If it is damaged in any way, get in touch with the haulage contractor.2. Transport the fi lter to its fi nal location, which should be horisontal and plane. The fi lter unit has a high centre of gravity. Secure the fi lter properly while transporting it or transport the fi lter lying in the horizontal position. Use the lifting lugs on the upper side (TSF4F and TSF8) for the lifting bracket by the inlet of the fi lter (TSF4-1200 and TSF8-1200) for lifting the fi lter or raising it from a horizontal position. An upright fi lter can also be lifted and transported by means of a forklift truck provided that the dust container has been dismantled and the forks are applied against the surface where the container is normally fastened to the fi lter. Be careful not to damage the compressor tank and other components on the underside of the fi lter. Caution! Forklift truck lifting is rather unstable; involves a high risk of the unit tipping over. 3. Open the inspection cover and check that the fi lter cartridges are secured in their appropriate position. If they have become loose during transport, fasten them and close the cover. 4. Connect the suction duct with control damper (no control damper is needed if the fan is equipped with frequency control). If any duct branches are to be connected, it is advisable to connect them as illustrated in A, since arrangement enables a lower pressure drop and lessens the risk of dust collecting at the joint. 5. Connect the power supply as shown in the wiring diagram (see the section entitled ”Electrical Connections”, etc.).6. Connect clean and dry compressed air to the header tank (4 bar).7. Start the fan, check that its impeller rotates in the right direction as shown by the arrow on fan casing (see under ”Electrical Connections as well) and set the appropriate airfl ow by means of the control damper or speed control unit, if installed. If the airfl ow is insuffi cient, this may be because the fan impeller is rotating in the wrong direction.8. If Absolent has recommended a pre-coating of the fi lter cartridges, this has to be carried out before the fi lter is to be in operation. The pre-coating powder is sucked into the unit via the supply air duct (0,125 kg/600 cartridge, 0,25 kg/ 1200 cartridge, see also sequencer settings

Pressure drop across new fi lter media: • On a normal airfl ow through clean TSF fi lter cartridges, the pressure drop across the fi lter cartridges is about 100-300 Pa. A lower air fl ow could mean that there is a leakage.

Preventive maintenance and regular service will lengthen the useful life of your installation. This will also enable maintaining consistent, high cleaning performance in the industrial environment.

Fault TracingIf the dust collecting capacity is low:• Check that the fan impeller rotates in the correct direction • Check the speed of the fan if it is speed controlled• Check the pressure drop across the fi lter. Higher than 2500 Pa and/or alarm signal from the sequencer• Check that any damper fi tted on suction duct between the machine and the fi lter unit is correctly set • Check the suction duct between the machine and the fi lter unit for leakage• Check that the duct system isn’t clogged

If the interval between fi lter changes in absolute fi lters is short (TSF4F) and/or if the fi lter isn’t fi ltering properly:• Check that the fi lter cartridges are intact. The fi lter material may be damaged due to careless handling. • Check that the fi lter cartridges have been correctly mounted and properly secured. • Check that the sealing strips of the fi lter cartridges aren’t damaged. • Check that the manometer is working properly (0 Pa when fan is shut down).

If the interval for servicing the fi lter cartridges is abnormally short: • Check that the compressed air cleaning mechanism is operating properly (see separate instructions for

electronically controlled pulse-cleaning system). • Check that the airfl ow conforms to sizing specifi cation for the system. Too high an airfl ow impairs the

cleaning function and shortens the useful life of the fi lter cartridges as well. • Check that the manometer is working properly (0 Pa when fan is shut down).

Service intervalIf the airfl ow is too low or if the pressure drop across the fi lters exceeds the in-service level (standard: 2500 Pa /alarm level), it is time to change or clean the fi lters. Filters should be cleaned or replaced when the pressure drop has reached the alarm level of the sequencer. The length of the service intervals varies between different applications. How to handle the fi lter medium while servicing the unit is described under the heading ”Replacing and Cleaning the Filter Cartridges”.

Replacing and Cleaning the Filter CartridgesInstructions1. Shut down the fan by opening the safety-isolating switch to isolate the power supply 2. Switch off the power to the automated pulse-cleaning system. 3. Open the inspection cover. 4. The fi lter cartridges and the fi lter chamber should be preliminarily cleaned by brushing and blowing the dust down into the dust container. Use a soft brush and a compressed air nozzle for this purpose. A way of preventing dust from escaping into the premises is to open and secure the inspection this open position; and then start the fan. Caution! Wear protective glasses and ear protection while doing this work. 5. Release the fi lter cartridges by backing off their quick-action annular fastener as described in separate instructions. Slip a plastic bag over the each fi lter cartridge before dismantling it to prevent dust from spilling on the outside the fi lter chamber. 6. Loosen the hoses to the manometers and the sequencer and blow them clean. Check that the manometers indicate 0 Pa. 6. The cartridges fi lters are washable up to three times. The simplest ways to wash them is spraying them with a high-pressure jet, fl ushing them with a water hose or spraying them in a chamber. Max. temp. 100°C, 5–7 pH. It is important to fi nd out if the dust collected in the fi lter contains environmentally dangerous substances so that they can be disposed of in accordance with local regulations. After it has been washed, the fi lter should dry by itself (approx. 1 week in room temperature). The absolute fi lter is not washable. It must be replaced when the pressure drop exceeds the max. permissible in-service level (600 Pa).6. Before fi tting the fi lter, check that its sealing strip isn’t damaged. The sealing strip on the absolute fi lter (TSF4F) should be seated upward. 7. Fit the fi lters according to separate instructions and close the inspection cover. 8. Start the fan and check the pressure drop. If the pressure drop across the fi lter cartridges is below 100 Pa at the rated airfl ow, check that the fi lter cartridges are properly fastened and that no other leakage has arisen. If the pressure drop exceeds 1200 Pa and washed fi lters have been fi tted, it is time to replace them or wash them in another way (get in touch with Absolent for advice). If the fi lter cartridges should be pre-coated, this has to be carried out before the unit is started. (See also ”Installation”, item 8).

Sketch 1: Fitting and removing the fi lter cartridges of the TSF4FSketch 1: Fitting and removing the fi lter cartridges of the TSF4FThe TSF4F has one fi lter fastener per fi lter cartridge, which consists of a clamping ring (A) with three bevelled dogs (AA), which is slipped over the fi lter cartridge (Fig. a). Each dog is positioned with its opening against one of fi lter cartridge (Fig. a). Each dog is positioned with its opening against one of three tension bolts (Fig. b). To secure the fi lter cartridge, turn the clamping ring and let the tension bolts (B) slide against the bevelled surface of the clamping ring. Removing the fi lter cartridges 1. After you’ve brushed off or blown the fi lter cartridge clean (don’t forget to clean the top of each fi lter cartridge) release the fi lter cartridges by turning the clamping ring (A) counter clockwise (left-hand fi lter cartridges) or clockwise (right-hand fi lter cartridges).2. Pull the clamp rings (A) over the fi lter cartridges, clean them and put them aside. Caution! Some are of right-hand and others are of left-hand design.3. When you’ve freed the fi lter cartridges, slip a plastic bag over them to avoid spilling dust outside the fi lter. 4. When you take the fi lter cartridges out of the fi lter chamber, lift up each cartridge, tip it inward and lift it out bottom end fi rst. Be careful so that the tension bolts won’t damage the gasket of the fi lter cartridges.Fitting the fi lter cartridges Fitting the fi lter cartridges 1. If new cartridges are to be fi tted, remove the support cage and the fi lter insert from the old cartridges by backing off the nut on the topside of the cartridge. 2. Wipe clean or vacuum-clean any dust that has fallen down into the air duct and landed on the sealing surface of the fi lter cartridges before fi tting them. 3. Lift the fi lter cartridges into the fi lter chamber with the upper section fi rst and place each on the appropriate air duct. 4. Slip the clamping rings (A) over the fi lter cartridges and fi t them against the tension bolts (B). Caution! Some are of right- hand and others are of left-hand design. 5. Secure the fi lter cartridges by turning the clamping rings clockwise (left-hand fi lter cartridges) or counter clockwise (right-hand fi lter cartridges) until the tension bolts reach the bottom in the groove (AA).6. Check that the fi lter cartridges are securely fastened, if not, the tension bolts will have to be adjusted.

GB Electrical connections and Adjustment

GeneralThe Absolent TSF Dust fi lter is standard-equipped with a so-called sequencer that electronically controls the automated pulse-cleaning system that cleans the fi lter cartridges. The sequencer consists of a microprocessor and a differential pressure sensor. The differential pressure sensor continually measures the pressure drop across the fi lter cartridges (the reading can be viewed on the display). The cleaning process starts either when the pressure drop across the cartridges exceeds the preset value (pressure-controlled cleaning) or at uniform time intervals (0 – 999 sec.) (fi xed time-controlled cleaning).

For the warrantee to apply, a qualifi ed person must carry out all the electrical wiring in accordance with local regulations.If the fi lter unit is equipped with extra electrical equipment, this equipment shall be wired according to the wiring diagram supplied with the fi lter unit.

Inspection the fi rst time the unit is startedMake sure that the fan impeller rotates in the correct direction indicated by an arrow on the fan casing/motor. If you cannot see the motor while the fan impeller is rotating, start the fan, read the pressure drop across the fi lters from the manometer, stop the fan, transpose two phase leads, restart the fan and read the pressure drop again. The connection that gave the highest pressure drop is the correct one.

Wiring the fan (TSF-4F)The fan must be wired according to the wiring diagram below.
