Water electret machine for producing FFP2, FFP3 & KF94 melt blown fabric

The latest developed water electret machine from DK machinery uses ultra-pure water to spray onto the base melt blown fabric, generating static electricity through the friction between the water and the cloth surface to achieve the electret effect. Melt blown fabric produced by our water electret machine can achieve low breath resistance (about 30-40% lower), high efficiency (oil up to 99.97), longer duration (up to 2 years).
