Vacuum filter type CC — Unique open filter drum design

The CC-filter design is based on the experience Valmet has gained from almost 2000 delivered drop-leg filters to customers worldwide.

The CC-filters are delivered with metallurgy suitable to any washing application in the fiber line and offers high washing efficiency and reliable operation. The filter is also frequently used in dewatering applications.

Unique open filter drum design Pulp washing using vacuum for wash water displacement and dewatering is a highly proven washing technology. However, the CC-filter’s unique open-drum design provides many benefits compared to conventional drop-leg drum filters. The open design of the filter drum results in lower weight being exerted on the construction while also reducing stress and stress corrosion on the entire drum construction, shafts and bearings.
