7.1 - FILTERS
After commissioning, the speed of filter fouling will depend on the care taken when cleaning the air flow circuits. Hence the frequency
of filter checks should be increased during this period.
Maintenance intervals
The filter life depends essentially on the amount of dust in the air and the efficiency of the filtration system. The filtration quality cannot
be maintained if the filter medium has been damaged during maintenance. We recommend that the filters be replaced once every two
years, even in the case of moderate use
Filter replacement method
During filter maintenance operations, it is important not to spread the dust that has accumulated in the filters.
Shut down the unit,
Access the filters by opening the door panels,
Simply pull on the filters
Pull out the slide-type terminal (present on the 39HXC, 39HXE & 39HXEZ models ≥ 3000 m3/h); the filters can then be removed. For
the other models, simply pull directly on the filters.
