About DSP-Filtertechnik
DSP-Filtertechnik GmbH from Perscheid (Rhineland-Palatinate) is a specialist in solid-liquid separation and develops and manufactures filter systems for the chemical and pharmaceutical industries. The portfolio includes automatic module filters, bag filters, edge-gap process filters, multi-layer filters, laboratory and pilot plant filters, pressure nutsche filters and single-layer filters, agitated pressure nutsche filters, candle filters, and custom designs. The value chain ranges from CAD design (Autodesk Inventor) via CNC machining, laser and waterjet cutting, and welding assembly by certified welding specialists qualified for special alloys, through to the assembly of ready-to-install filter systems with accessories such as membrane compressors, membrane safety valves, fittings and valves, and cranes. Products are manufactured in stainless steel (including 1.4404, 1.4435, 1.4539, 1.4571) and in the special alloy Hastelloy (2.4602, 2.4605); surfaces are pickled and passivated, electropolished, ground/brushed, or glass bead blasted. In addition, the company offers conversions and retrofits of existing systems, a rental fleet of filter technology, and a stock of filter media. The products are designed for use in EX zones and meet the requirements of the AD2000 code of rules.
