295*295 Special Square Oil Filter Paper for Power Plants

Oil filter paper is suitable for filtering transformer oil, turbine oil, mechanical oil, and diesel; refining lubricants and filtering petroleum jelly in refineries; filtering for waste oil regeneration, insulating varnish, dyes, beverages, and fine chemicals. Oil filter paper offers excellent filtration and absorption properties along with considerable compressive strength. It is suitable for filtering industrial organic suspensions such as petroleum, chemical products, and industrial oils to separate solid and semi-solid impurities. For example, when used with filter presses, it can filter transformer oil, turbine oil, molten paraffin, synthetic resins, dioctyl sebacate, and various other organic liquids. Oil filter paper is not suitable for filtering aqueous or other inorganic suspensions.
