Vacuum drum filter - VDrF

A rotary vacuum drum filter is one of the oldest filters applied in the chemical process industry. It consists of a drum which is divided into sectors, each forming a separate vacuum cell. The cake can be washed easily on drum filters.

Following the acquisition of KHD-Filtrationstechnik and continuous further development work with 760 vacuum drum filters supplied, ANDRITZ can also draw on extensive filtration know-how in this sector. Experience gathered in pressure and vacuum filtration over more than 30 years has been applied in practice in this latest generation.
