Pressure Nutsche Filters

S2’s Pressure Nutsche Filters (PNF’s) are designed in sizes from 300mm (12 inches) to 2.5m (100 inches) in diameter, in a wide range of material types and grades for pressures up to 300 psi (2068 kPa) or full vacuum.
As standard the S2 PNF comes with an innovative lid that is hydraulically operated by one person with single point, quick and safe securing. The unit can be adapted to handle a wide range of flow rates and solids loading which can be discharged in dry or slurried form. By providing the required connections, the S2 Pressure Nutsche Filter can be designed to wash and dry, with the design allowing for fast and easy cake discharge and facilitates interrupted service flows.
In general, S2’s PNF’s are ideal for laboratory, pilot or batch production applications and for easily filtered material such as carbon particles, salts and other products where a cake thickness of 150mm (6 inches) or more can be attained. Further information is shown below.
