The oil removal filter is a three-stage oil removal equipment that uses ultra-fine microporous filter tubes as the main filter material to perform coarse filtration, semi-fine filtration, and fine filtration on compressed air. It adopts comprehensive mechanical separation and micro-filtration. The principle of fiber filtration and microporous media cohesion and growth has the characteristics of high filtration efficiency, small size, long life, high pressure resistance, good oil removal and purification effect, low pressure difference, easy operation, and low maintenance costs. And it has certain dehumidification and drying capabilities. This device has high purification efficiency and low investment cost, and can be widely used in process gas for pneumatic control, pneumatic instruments, and pneumatic components in chemical, metallurgical, energy, light industry, electronics, pharmaceutical, food, cigarette, cement, petroleum, textile and other industries. , providing high-quality pure compressed air. Special designs and services can also be provided to users.
