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.

When to change the filters?
When the “Pressure Diff” gauge is above 15 cm H2O, the filters are probably clogged.
A vacuum gauge measures the difference between the under pressure above the filters and inner filter house.
This readout indicates the degree of pollution of the filters, with this system you can always keep an eye on
the condition and pollution of the filters inside the dust extractor. It can also help you fine-tune the airflow
when precise adjustment is required for the job.
If the dust collector loses suction power first try the following before continuing:
1.
Check if the butterfly valve on the inlet 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 of the water separator. Turn on the compressor again
until it is fully pressurized, now use the air gun to completely empty the pressure tank.
3.
Close the butterfly valve and only turn on the compressor, 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 “Pressure Diff” gauge keeps indicating more than 20 cm H2O, the filters probably need to be
exchanged.
When the machine still does not perform adequately, the filters probably need to be exchanged.
Pressure Diff.
This indicates the pressure difference
between the clean and dirty side of the
filters. To check the status of the filters.
