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.
6.1
When to change the filters?
When the “Pressure Diff” gauge is above 20 cm H2O, the filters are probably clogged.
If the vacuum cleaner loses suction power first try the following before continuing:
1.
Check if the blower throttles on the silencers are 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 “Pressure Diff” gauge keeps indicating more than 20 cm H2O, the filters probably need to be
exchanged.
Or when the machine still does not perform adequately, the filters probably need to be exchanged.
If the silencers blow 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!
Pressure Diff.
This indicates the pressure difference
between the clean and dirty side of the
filters. To check the status of the filters.
