Spiral Perforated Metal – Center or Outer Tubes

Filter paper is processed by mixing plant fiber pulp and a little cotton pulp. Because of its fiber structure, leaving numerous tiny holes for liquid particles passing through and leaving solid particles out, which is the basic principle of solid and liquid separation.

• The filter paper can separate impurity particles from the liquid and extend engine and auto service life.
• High filtration efficiency. 98% filtration efficiency of 4 µm particles and 99% filtration efficiency of 6 µm particles.
• Up to 800 L/m²/s air permeability.
• Oil filter paper can withstand up to 600 kPa pressure.
• Up to 70 70 mN/m high stiffness of cured filter paper.
