Oerlikon says electro-charging unit greatly improves filter performance
Posted July 30, 2020
NEUMÜNSTER, Germany – Spunbond and meltblown materials can be electrostatically charged to improve their filter performance.
Oerlikon Nonwoven’s ecuTEC+ electro-charging unit is part of the delivery scope of all meltblown systems currently sold for the manufacture of protective mask nonwovens.
Oerlikon Nonwoven’s electro-charging unit rounds off filter nonwovens systems. The patented Oerlikon Nonwoven solution is characterized 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 remains high for filter media
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 recognized by the market as being the technically most efficient method for producing highly-separating filter media made from plastic fibers.
The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems.
