Characteristics of filter core
1. Breathable: The filter core adopts imported hydrophobic and oleo-phobic fiber media filter material, and at the same time, it adopts a skeleton with good permeability and high strength to reduce the resistance caused by filtration.
2. High efficiency: The filter core adopts the fine opening sponge of American technology, which can effectively prevent the oil and water from being carried away by the high-speed air flow, so that the filtered small oil droplets gather at the lower end of the filter core sponge and are discharged to the bottom of the filter container.
3. Airtight: The junction of the filter core and the filter shell adopts a reliable sealing ring to ensure that the "air flow is continuous" and prevent impurities from directly entering the downstream without passing through the filter core.
4. Anti-corrosion: The filter core adopts anti-corrosion reinforced nylon end cap and anti-corrosion filter skeleton, which can be used in harsh.
