Depth filter cartridges are used to reduce particulate load before fine filtration (polishing) or to keep the recirculating process fluids clean.  These are conventionally spun or wound type filter elements but a depth type media for pleated elements is also available. Nominal filter elements are used for general particulate reduction and absolute filter elements are used for applications that demand high removal efficiency. Our depth filters can be used for industrial and food applications with our FDA approved media. Available materials (Nominal or Absolute): 1) Polypropylene 2) Nylon 3) Polyester 4) Cotton 5) Glass fibre 6)PPS.
