Application
The BDC-99 is a very powerful mobile dust extractor. This high performance machine is exclusively designed
and built to be used in combination with Blastrac machines. It is equipped with 9 pieces of specially designed
high quality M-class cartridge filters.
The dust extractor is provided with an air pulse cleaning system which increases the life of the filter cartridges.
This system works by use of pressurized air, built up by a compressor. The air is led through a water separator
to the pulse system.
The conditioned air then passes a control valve which regulates the system pressure, and then builds up
pressure in the pulse tank. The pressurized air is used to generate a pulse of air which cleans the filters from
the inside. With every pulse of the pulse system, dust and particles are released from the filter surface.
Contact Blastrac B.V. for the correct execution and combinations.

Full overhaul and cleaning of the complete machine.
The time indications are based on uninterrupted operation. When the indicated number of working hours is not
achieved during the corresponding period, the period can be extended. However a full overhaul and a technical
inspection must be carried out at least once a year, consisting of inspection of filters for damage, air tightness
of the machine and proper function of the control mechanism. This technical inspection shall be carried out by
the manufacturer or an instructed person.
Due to different working conditions it can’t be foreseen how frequently inspections for wear check’s,
inspection, maintenance and repair works ought to be carried out. Prepare a suitable inspection schedule
considering your own working conditions and experience.
Pay attention to unusual noises or strong vibrations. Check for the cause of every big change. Call a technician
if you have doubts about the cause or when a repair without a technician seems not possible without damages.
Only use genuine Blastrac spare parts.
Our specialists will be happy to assist you with more advice.

Prior to any repair works on the dust collector and its drives, secure the dust collector
against unintentional switching on. Put the dust collector to its safety off position. Also
make sure there is no air pressure on the pulse system. The machine is in a safe condition when
it cannot generate any hazard.
Follow additional operating and maintenance instructions of Original Equipment
Manufacturers if included during your service and maintenance work.
Further is advised:
Store the cleaned and dry machine in a dry and humid free room. Protect the electrical motors from moisture,
heat, dust and shocks.
All repair work must to be done by qualified Blastrac personnel, this to guarantee a safe and reliable machine.
Any guarantee on the machine is expired when:
Non original Blastrac parts have been used
Repair work is not done by qualified Blastrac personnel
Changes, add on’s or conversions are undertaken without written permission of Blastrac BV
Screws, bolts etc. that have been removed must be replaced with those of the same quality, strength, material
and design.
Do not weld, flame cut or perform grinding works on or near the dust collector. Danger of fire or explosion
exists! Provide adequate ventilation when working in a confided space.
Secure the maintenance area if necessary.
6.1 When to change the filters?
If the dust collector loses suction power first try the following before continuing:
1. Check if the silencer is fully opened.
2. Ensure that the compressor is fully pressurized and then turn it off. Remove all moisture from the
compressed air tank by using the drain valve. Turn on the compressor again until it is fully pressurized
again, now use the air gun to completely empty the pulse tank.
3. Only turn on the compressor, and keep the fan unit turned off. Let the machine pulse for about a half
an hour. This action will clean the filters from the inside.
When the machine still does not perform adequately, the filters probably
need to be exchanged.
If the silencer blows out dust, stop the machine immediately!
This means probably that a filter is damaged or not fitted properly inside
the filter chamber. Check the filters and replace if necessary.
When a filter was damaged, has leaked or was mounted incorrect, it has
to be replaced. The compartment above the filters, the connecting air
hoses and the silencer also have to be cleaned thoroughly.
Continuing work with a broken/leaking filter can cause serious
damage to the machine and is a health hazard!
Never expose the filter cartridges to moisture!

6.2 Changing the filters
Read chapter 3 Safety before changing the filters.
Operators should observe any safety regulations appropriate to the materials being handled.
Observe the national regulations in force both during exchange and disposal of the old filters.
Warning! Always wear Personal Protective Equipment, the dust can be hazardous to the health!
Make sure you have enough sturdy plastic bags or use big bags for the disposal of the old filters.
Observe the national regulations in force both during exchange and disposal of the old filters.
Remove the filter house door.
Loosen the nut + washer (2).
Remove the locking bar (1).
The filter bracket will now be tilted downwards so
the filters can be taken out easily.
Slide out the filter (3) and put it in a sturdy
plastic bag.
Close the bags properly.
When mounting new filter cartridges pay
attention that their gaskets at the upper side lies
firm at the sheet steel of the filter chamber. A tilt
of the filter cartridge results in leakage and
contaminants will be sucked in the clean part and
consequently will blow them backwards in the
outer air.
When a filter was damaged, has leaked or was mounted incorrect, it has to be replaced. The compartment
above the filters, the connecting air hoses and the silencer also have to be cleaned thoroughly.
If the silencer blows out dust, stop the machine immediately!
This means probably that a filter is damaged or not fitted properly inside the filter chamber.
Check the filters and replace if necessary.
Continuing work with a broken/leaking filter can cause serious damage to the machine and is a
health hazard!
Pull out the mains plug before you start
Always wear gloves and a dust mask of at least class FFP3
Use an extra vacuum cleaner in order to work as dust free as possible

6.3 Pulse system
The Dust collector is provided with an air pulse cleaning system which increases the life of the filter cartridges
and ensures a constant suction power.
The system works by use of pressurized air, built up by a compressor
The air is led through a water separator to the pulse system.
The cooled air passes a control valve, which regulates the systems pressure , and then builds up pressure in
the pulse tank.
Normally the pressure in the system lies between 6 and 7 bar. The control valve is activated above 7 bar.
This provision is to ensure that the pressure in the pulse tank remains within safe limits.
The safety valve mounted on the compressor is activated at approximately 10 bar.
This provision is to ensure that when there is a defect in the Control valve, the pressure in the pulse tank
remains within safe limits.
If the pressure of 6 bar is not reached, it is possible that either the filter of the water separator or the air filter
of the compressor is dirty.
If inspection of the water separator and compressor shows no abnormalities, it is possible that either there is a
leakage in the air tubing, or the control valve is defect. In that case replace the defective parts or have it
checked by Blastrac.
When there is pressure but the pulse system does not function, there might be a problem in the electrical
system which controls the pulsing system. Check the wiring and the PLC-settings.
It is advised to contact Blastrac Support in order to prevent operational problems.

6.4 Water separator
The water separator filters dirt particles, oil and water from the air.
It is recommended to replace the filter after every 200 operating hours.
1. Head
26. Valve
27. Floater
28. O-ring
29. Bowl
30. O-ring
31. Filter element
36. Louver
This spitter type drain operates momentarily
when a rapid change in air flow occurs or when the supply
pressure is reduced.
The separated water will be drained in the ‘Drain Box’
It has to be emptied daily.
Checking the filter:
Unscrew 29. Bowl and keep it upright, so that the vlotter and
o-ring will stay in place.
Check 31. Filter element on contaminants and calcium deposits.
Clean the filter with warm water and pressurised air or replace if
needed.
6.5 Compressor
Replacement or cleaning of the air filter of the compressor is depending on the environment in which the dust
collector is operating.
Check the filter every month.
Unscrew the cap and take out the
filter inside.
Clean or replace if necessary.
