Ahlstrom FiltEV® is a new, comprehensive Platform of High Performance Filtration Materials for Battery Electric Vehicles. It includes solutions for cabin air, transmission and battery cooling.
The portfolio is based on proprietary three-layer wetlaid technology and offers low pressure drop with high dust holding capacity and good mechanical resistance. In addition, we have developed glass microfiber based solutions for battery electric vehicles.
Cabin air filtration - Pure air for passengers
Cabin air quality is an increasingly important factor in the design of the new generations of vehicles. By filtering particles, microorganisms and harmful gases, air filters create a healthier cabin environment and improve the driving comfort.
• Particulate portfolio protecting against coarse, fine and ultrafine particles, including bacteria and viruses
• Carbon portfolio combining removal of particles and gases for an increased level of protection
The benefits include reliable filtration efficiency, up to HEPA level, optimal gas adsorption and excellent pleatability delivering highest converting efficiency.
