VARIGLASS is a pre-filter with very high dust storage capacity. The particular progressive structure of the filtering septum with randomly arranged fibers, with density
larger on the clean air outlet side, ensures better filtration and longer operating life.
The adhesive agent contained on the filter media gives to VARIGLASS pre-filter, a capacity
to absorb and accumulate dust.
This pre-fiter is therefore particularly recommended as pre-filter in all those applications
where the filter is used in hard conditions (turbogas installations, in areas where the quantities
of dust are very high.)
