PSL’s proven Agitated Nutsche Filter Dryer technology

Agitated Nutsche Filter Drying (ANFD) is a batch filtration technique using vacuum and/or pressure in a closed vessel. The filtration technique uses PSL’s distinctive agitator design for excellent cake agitation in applications such as dye, paint, silicon, waste water treatment and pharmaceutical production.

The GFD® Filter Dryer overcomes challenges with commonly used methods of Buchner filtration and oven drying. Ideal for running feasibility studies and trials, the GFD® efficiently performs laboratory process development, with direct scale-up to pilot plant scale and commercial production.

The GFD® can be integrated in fume hoods while maintaining good process visibility, batch homogeneity and reduced product exposure.

  • Combined filtration and drying
  • Semi-automated operation
