Spunbonded and meltblown materials can be electrostatically charged to improve their filter performance. The ecuTEC+ electro-charging unit is part of the delivery scope of all meltblown systems currently sold for the manufacture of protective mask nonwovens.
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 among numerous variation options and set the optimal charging method and intensity for their specific filter applications. EPA- and HEPA-class filter media can also be manufactured using ecuTEC+. As a result, the concept distinguishes itself from other technologies available on the market.
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.
