OPF Series Oilfield Pleated Filter Cartridges


OPF Series Oilfield Pleated Filter Cartridges are made of PP, Polyester or Borosilicate Glass Fiber pleated media. Pleated design enlarges the filtration area, having superior flow characteristics with very low pressure drop compared to depth media of micron rating filters. Oilfield pleated filters have high dirt holding capacity, and long service life with stable filtration efficiency, therefore, they are used widely in significant industrial applications: oil field, power plant circulated water treatment, petroleum industry, solvents, selected acids & lyes and chemical industry etc.
