Maintenance
Explosion-proof filters are based on the same tech-
nology as conventional filters, and they work in the
same way as conventional filters of the same type
and construction
Maintenance applies mainly to the filter element.
Check the filter regularly and replace it, if neces-
sary.
The service life of a filter depends mainly on how
contaminated the air is. Check the filter in intervals
that are short enough so that you can anticipate any
defects or problems before they actually occur.
Replace the filter immediately if any of the following
is true:
the filter is defective
there are hygiene problems (micro-organisms,
fungal spores, odours, etc.)
the maximum filter usage time has been
reached (VDI 3803, part 4)
the defined final differential pressure has been
reached
For more recommendations regarding the max-
imum usage time see SWKI 2003-5, VDI 6022,
VDI 3803 and EN 13053.
You may replace a filter even before the defined
final differential pressure has been reached if this
is more economic.
Disposal
ENVIRONMENT!
Risk of harm to the environment due to the incor-
rect handling of hazardous materials and sub-
stances.
Filters and cleaning materials that have been
contaminated with bacterial, toxic or radioactive
particles are considered hazardous waste and
have to be disposed of by an authorised business
in compliance with local regulations.
Disposing of filter elements with household waste is
allowed only in the following cases:
For unused filter elements
For filter elements that have been exposed
only to atmospheric outdoor air
Ordering replacement filters
To ensure permanent protection from particulate
matter and other pollutants we recommend using
only original TROX filters.
Original TROX filters carry a sticker on the frame
with information on how to order replacements.
To avoid downtime of the ventilation and air con-
ditioning system, we recommend you to always
have the required filters in stock.
