The patented Oerlikon Nonwoven solution is characterised by its exceptional flexibility: ecuTEC+ stands out above all as a result of its diverse applications, which can be electro-charged. Nonwovens manufacturers can freely choose between numerous variation options and set the optimal charging method and intensity for their specific filter applications. And EPA- and HEPA-class filter media can also be manufactured using the ecuTEC+. As a result, the concept distinguishes itself from other technologies available on the market.

Demand for filter media remains high
The demand for filter media – and those made from meltblown nonwovens in particular – has been extremely high since the start of the coronavirus pandemic. The Oerlikon Nonwoven meltblown technology – with which nonwovens for respiratory masks can also be manufactured, among other things – is recognised by the market as being the technically most efficient method for producing highlyseparating filter media made from plastic fibres. The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems.
