Bag Filters Nano Wave® technology incorporates a multilayer filter blanket that has fine wavy fibers, protected with a prefilter layer that separates fine dust. The wavy profile of this extrafine fiber increases the effective area of the filter, which translates into minimal initial head loss and greater dust retention for the unit. Bag filters with Nano Wave® technology are free of electrostatic charges, comply with the new ISO 16890: 2016 regulations and meet the hygienic requirements for air filters, making them suitable for application in sensitive areas.
