separated out, partly by centrifugal force and partly by gravity. Air and finer particles then pass
through the filter system where they are separated. The separated dust accumulates in the
cyclone until the machine is switched off, when it drops through the bottom flap into the plastic
bag.
4. Filter cleaning
The machine is designed for automatic jet-pulse filter cleaning, which can clean the filter by itself
from time to time. Air compressor keeps supplying compressed air @4-6Kg to an air tank.
Controller controls the 3 valves open/close with a pre-set frequency and sequence. When a valve
open, the compressed air blusters into the filter inside out, blowing off dusts from the filter
surface. When the vacuum starts operation, the jet-pulse filter cleaning is automatically working.
Each valve open/close at a pre-set time interval and frequency.
If suction becomes poor, the filter needs to be replaced. The plastic bag may only be replaced after
cleaning the filter. The plastic bag must be tied up after removal. Only use original parts.
5. Filter change
Risk of dust dispersion -Use of personal safety equipment Unhealthy dust can be spread
during filter change. Accordingly, the user should wear protective glasses, protective
gloves, and a breathing mask conforming to protection class FFP3.
Turn the machine off and pull the plug out of the socket.
Loosen the clamp between the upper and lower housing. Remove the hose connection Lift out the
filter holder and place it carefully on a table. Remove all screws and then remove the filter and
place it in a plastic bag. Insert a new filter in reverse order. Tighten the screws hard. Only original
filters may be used.
6. DUST STORAGE SYSTEM
The dust extractors are mainly equipped with Longopac system for effective dust storage or a
regular plastic bag system depending on model. Longopac is a 22 m long plastic tube that will be
divided into plastic bags using the zip ties attached with the machine.
To assemble a new Longopac bag
: Release the belt holding the last bag. Remove the holder,
put in a new Longopac bag & pull out the inner end upwards. Assemble the holder on to the
machine and strap the opening facing upwards with the belt. Pull down the outside end and close
