schematic anfd and barrier isolator lrStandard Group of Companies is a specialist at manufacturing process equipment such as Agitated Nutsche Filter Dryers (ANFD's). For ANFD's we manufacture Rigid barrier isolator systems with either a negative or positive pressurised internal environment depending on the processed media.

Our negative (-ve) ANFD barrier isolators are essential where the process media is hazardous, dangerous or has an unacceptably high toxic level. This design is the default standard for ANFD applications however if required, our positive (+ve) barrier isolators can be supplied where external contaminants can not be allowed to enter the processed batch substance.

Our Group ANFD designs 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 and can be supplied in a wide range of materials including Hastelloy.
