The GFD®Pilot is an Agitated Nutsche Filter Dryer (ANFD) that carries out solid-liquid separation processes at kilolab and pilot scale. It facilitates feasibility and proof of concept activities developed during smaller scale research and development stages. In spite of being a smaller, compact filter dryer, it provides the quality, reliability and efficiency of the full size PSL ANFD filter dryers. PSL’s unique GFD® technology was developed to overcome the well-known production challenges faced by manufacturers when using traditional production methods such as Büchner filtration and oven tray-drying. It consists of an agitated vessel designed to work under vacuum and under pressure. The vessel can be made of Borosilicate 3.3 glass, 316L Stainless Steel or Alloy 22 and has a heated jacket for efficient drying. Solid-liquid separation is performed within the unique filtration basket, which can be removed to ease and maximise product recovery. The GFD®Pilot technology is designed to be the logical scale-up ANFD from the GFD®Lab which is used in laboratory conditions. It assists in evaluation and development of the desired end product prior to scaling up to commercial production. Features and Benefits Combined Filtration and Drying The GFD®Pilot is an all-in-one filter dryer designed for use at pilot plant production scale. It complies with Good Laboratory Practices (GLP) and is commonly used for pharmaceutical and fine chemical processing applications.
