Filter Medium
The filter medium must ensure high filtration efficiency for the specific dust type and durability suited to the installed cleaning system.
- Permeability measures the flow rate through the medium per unit area at a fixed ΔP.
- Weight (grammage) defines the material amount per unit area.
- Filtration efficiency indicates dust retention for a given particle size, generally inversely proportional to permeability.
- Surface treatments enhance media properties through specialised processes.

NANO-FIBRE
stronger, lighter, more durable
Nano-fibre treatment involves the application of a web-like layer of fibres with diameters smaller than 0.5 μm. This thin layer is applied to the surface of standard spunbonded media, enabling a combination of low emissions and high air flow rate.
