S2 ANF manufacturingS2 Engineering (S2) provide a full turnkey sevice for Agitated Nutsche Filter's (ANF's) from design and manufacture to assembly, installation and commissioning. Our ANF product range also includes the manufacture of modular Filter Dryers (ANFD's) - read more

Like our ANFD's, our modular ANF's are innovatively designed and engineered to help improve plant operational processes efficiency. We can also provide ANF's with barrier isolator (Glove box) technology for contained discharge and/or charging operations. See our Group Isolator company here and/or see the red tab option below.

We are experienced in process media filtration and provide equipment with high levels of safety and quality that meets all appropriate industry regulations.

Our ANF's feature a differential mixing agitator and paddle that moves vertically for a thorough mix performance. The filter drier agitator consists of a series of sharp curved blades that achieves mixing penetration into difficult cakes without undue product stress. While moving and lifting the cake media around the internal clearances within the filter, agitation mixing efficiency is achieved through differential velocities. Once processed through the filtered product slurry can then sent/pumped to subsequent operations or storage vessels.
