Filter sets
All Aerferrisi heating units are equipped with a filter set that can retain domestic dust and
air impurity. The position of said filter corresponds directly to the unit’s air inlet and can be
easily removed to verify its state of efficiency and, if needed, to replace it.
Aerferrisi supplies simple sheet filters or filters with complete frame, directly applicable to
the heating unit.
Their composition is 100% polyester fiber with a 9mm thickness and a capacity to
accumulate dust up to 440gr/sq m. They belong to the EU3 filter class and are selfextinguishing
with a change of dimensions in heat above 80°C. These are filters that can
usually be employed in ventilation and air conditioning systems. In the 0/1/2 sizes they are
supplied with a special clamping rubber band, while in sizes 3 and 4 they are available
with a sheet-metal frame.
