Star product BaglessPlus
Disc filter sectors that do not require maintenance-prone filter bags - unthinkable until 1998. Since its first installation in 1998 in Shotton (Great Britain), the successful product BaglessPlus from Voith has proven itself in countless disc filters. It is not without reason that since 2002 Voith has been equipping each of its sold disc filters with the filterless sectors that achieve best results and highest customer satisfaction.

The patented nozzles optimize disc filter operation
The new generation of V-bags from Voith achieves longer service lives and therefore more reliable and stable operation of the disc filter. The integration of the Protector sheet in the filter bags offers the bags additional protection against damages caused by sharp sector edges. This substantially extends the service life and as a result the maintenance intervals of the disc filter. In addition, capacities can also be adjusted by means of special blind strips on the filter bags.
Various filter bags are available for all disc filters from Voith and other manufacturers. If required, Voith offers filter bags tailored to customer needs:
- Voith V-bag P: Polypropylene bag
- Voith V-bag C: Corrugated polypropylene bag
- Protector sheet: Can be combined with V-bag C and V-bag P
