Cylindrical Sintered Metal Powder Filter Elements Porvair Filtration Group manufacture a range of industry standard stainless steel filter elements suitable for use in a wide range of industries, including petrochemical and pharmaceutical. The robustness of design, that is provided by a fully welded metallic element or cartridge, is required to resist deterioration in harsh operating environments where the fluids present are aggressive, high temperatures are experienced or where the operating differential pressures are high. • atalyst recovery and retention C For use in the collection of catalyst dust on various types of catalyst hoppers or FCC regenerator stream in refineries. For some filtration applications, the use of a conventional disposable polymeric cartridge may simply be environmentally unacceptable and the use of a re-cleanable element will often give more cost effective filtration. • hemical production C For applications in the clean-up of hydrogen process gas, and in the manufacture of magnesium nitrate and caustic solutions. These filter elements are offered in the following media configurations: • team S For applications in the chemical, food, beverage and pharmaceutical industries. Sinterflo® F Sintered Metal Fibre Sinterflo® P Sintered Metal Powder Sinterflo® M Metal Mesh Sinterflo® MC Sintered Metal Composite Typical applications for our Sinterflo® P elements include the following: • olymer melt P For applications in the manufacture of polypropylene film. • iquids and liquid backwash L For applications in catalyst steam backwash applications and in the manufacture of polyols. Sinterflo® P is a robust material manufactured from sinterbonded metal powders. Primarily produced in 316L grade for use in temperatures up to 420ºC (788ºF), depending on process conditions, and offering resistance to most chemicals, Sinterflo® P media can also be produced in other grades of stainless steel and alloys such as Inconel®, Hastelloy® and Monel®. Sinterflo® P powder media can be manufactured in both disc format or in cylinder format. For cylinders, our isostatic pressing ensures greater media uniformity with no welds, leading to increased corrosion resistance.
