• The steel collection pan should be inspected, cleaned
and emptied on a monthly basis.
• The pre-separator (located on the bottom of the main
filter) should be inspected and cleaned on a monthly
basis, using an industrial vacuum cleaner.
• The pre-filter should be inspected and cleaned on a bi-
monthly basis, using compressed air or an industrial
vacuum cleaner.
• Frequency of cleaning and emptying depends on a
number of factors such as the type of welding process
and the frequency of use.
• The main filter should be checked every month to
ensure that there is no damage.
• The seals of the main filter should be checked every
12 months.
• When fume extractor is not in use, wrap cord and place
in the handle opening. Store fume extractor in a dry
place.
• When fume extractor is in use, take precaution that the
cord is protected from damage and not a tripping
hazard.

WARNING
The particulate matter collected in the unit may be
dangerous to your health. Take necessary precautions so
that you and your fellow workers do not breathe dust and
particulate. Wear a suitable respirator when disposing of
the particulate. Follow local Environmental regulations
for disposal of filters and particulate matter.
rePlaCing the Filters
The main LongLife-H filter and the HEPA filter cannot be cleaned and
therefore they have to be replaced periodically. It is recommended to
replace all filters at the same time. WARNING
A saturated filter often contains dust and dirt particles
which could form a health hazard upon inhalation. When
replacing the filters, always wear a high-quality and
approved face mask or respirator. Wrap the filters in a
properly closed plastic bag and dispose of it in
compliance with local regulations.
Replace the filters in case of damage or when the extraction capacity
has become insufficient due to the amount of particulate in the filter.
Periodic check of the filters is required to maintain optimal
performance and life of unit. Filter performance/life is dependent on
variables such as:
- Welding application/processes
- Oil involved in weld processes
- Dust/grinding particulate
- Proper usage and maintenance
Note: There is no filter clog indicator on this machine.
