The quality of the filter elements used is
particularly important on account of the
special conditions prevailing when using
a cut-off machine (extremely high dust
loads and high dynamic loads).
STIHL air filters have been specially
designed for use in cut-off machines and
therefore meet the special requirements
imposed with regard to their mechanical
design, the materials used and the
manufacturing quality.
:
Extremely uniform pore size, folds
and strength of the filter paper
:
High compression strength and
dimensional accuracy of the filter
cartridges
All the air filter components in this
machine are matched with one another
as regards filter capacity and air
permeability.
