Breathing masks protect against fine dust, smoke or liquid mist (aerosol) and provide some protection against bacterial and viral droplet infections. Particle filtering folding or molded masks are divided into the protection classes FFP1, FFP2 and FFP3 (Filtering Face Piece). The protection class defines the structure of the filter materials.
Ultrasonic technology is the ideal and economical method for producing all types of protective masks. Depending on the mask type, different cutting and sealing applications are used. For example, multi-layer filter material can be made into finished masks using Telsonic's cut'n'seal technology. Ultrasonic technology can also be used to attach additional parts such as nose-shaped brackets, valves or carrying straps.
