Into the filter layer of cartridge type, interior exterior central tube be gather perforate or stainless steel, or through surface resistance to alkali process (plastic-spraying, plating, painting
Paint) metal or plastic cylinder, filter layer is pleated or phozy, is the coalescence that can coalesce moisture content in fluid on the outside of exterior central tube
Layer, coalescing layer outside is protective layer, and filter core both ends are buckled with end cap, it is characterized in that：Described filter layer is with filtering accuracy micron order
Glass fiber filter paper layer is matrix, inside and outside compound nonwoven cloth, the protective layer of nylon (polyester) net composition；Described water droplets coalescence
Layer, using glass mat as matrix, lining non-woven fabrics on the inside of glass mat, outside is bundled in exterior central tube with glass fiber plastic-spraying net
On, outermost surface cover acrylic fibers (terylene, polypropylene fibre) cotton-padded covering.
The high-precision filter element of the present invention can work in height is containing alkali concn, high workload pressure, high-temperature oil liquid, and filter material is constant
Shape, do not puncture.
