This filter is made of super fine polypropylene fiber by hot melt entanglement. The super fine fibers form a 3 dimensional micropore structure by self binding and entanglement.

The holes are even in size, poisonless and odorless. The design of deep filtration with sparse outside and dense inside is adopted. It not only maintains stable flow rate, pressure difference and service time, but also has excellent deep filtration effect and pollutant accumulation.

It is a widely used PP filter with high efficiency, low pressure drop, and acid and alkali resistance. It is specially designed for circulating filtering and cleaning of oil sludge inside engine.
