Frequency conversion screw oil filter
When the frequency conversion screw machine is used for a long period of low frequency, the temperature is usually low, the water in the oil barrel is more, and the waterproof ability of the filter paper is higher.
When the frequency conversion screw machine is used at low frequency, the pressure of the oil system will be low, and the oil filter must have low resistance and good gas permeability.
The frequency conversion screw machine is basically long-term loading and running. In the same running time, the actual running time is longer than the power frequency screw machine. The higher the requirements for anti-carbonization and filter paper dust holding capacity of the oil filter paper
