Filter dryer with containment system for hazardous materials
Ensure operator safety and product integrity during hazardous material processing with a filter dryer designed for seamless operations and precise containment.

Filters, Dries, and Contains Hazardous Materials
The COMBER Pressofiltro® Series PF 50 – PF 2000 is an engineered solution from HEINKEL Group designed to meet rigorous industrial requirements for filtration and drying. Unique in its integration of an agitated Nutsche filter with a containment system, it addresses the high-stakes challenge of handling hazardous materials safely. Utilizing containment glove boxes, it ensures contamination-free product handling, crucial for maintaining purity in pharmaceutical ingredients and specialty chemicals.
The system supports operations such as batch or continuous processing for a variety of materials, including slurries and cakes. It features variable design capacities from 0.13 to 2 m² filter area and slurry volumes ranging from 55 to 2,000 liters. Engineered to adhere to cGMP and FDA guidelines, it employs HEPA-filtered air handling to maintain containment levels down to 10 ng/m³ TWA.
Constructed with high-grade materials like stainless steel and Hastelloy, it offers exceptional resistance to corrosive substances. The system’s automated features include a PLC-controlled interface, enabling seamless integration with existing production lines. Enhanced by options like dust filters, CIP systems, and vacuum units, the COMBER Pressofiltro® ensures both efficiency and safety in demanding applications.
