AsphaltStar is a range of needle felts for asphalt plants’ dust collection applications. The felt gives best performance and provides extended filter bag lifetime.

AsphaltStar structure

AsphaltStar structure is based on different temperature resistant polymers stapled as a scrim support fabric using needling technology. Different raw materials can be used alone or combined together. The felt can be given a surface treatment consisting of water and oil repellant.
