The effective filtering of large volumes of air is the primary task of NESTRO's intermediate filter. The designed -in low up-current speeds and the permanent discharging ensure a high system availability. The top-down cleaning and the large pre-filter chamber provide low turbulence filtration, which guarantees long filter life.
The vacuum technology developed by NESTRO guarantees high dust reduction at the highest energy efficiency level with up to 30% energy saving compared to overpressure systems. Filter cleaning using compressed air (Jet") is the best option for the paper and cardboard packaging industry since it enables an on-line operation.
