The Frouno filter fabric (filter class G4) consists of disorderly folded non-woven twisted synthetic fibres of different thicknesses, which are reinforced with an artificial binder (or thermally) to form a strong and stable filter fleece. The material has extremely low pressure loss and high dust accumulation due to the progressive construction of the fibres.

Frouno G4 is suitable for the production of filters for air handling units (heat recovery units, filter cartridges) for dust or pollen collection. The recommended replacement interval is approx. 3 months or as recommended by the manufacturer/technology supplier and according to the intensity of air pollution.
