Answer: The internal automatic drainer and the external automatic drainer in the filter accessories are used to automatically discharge the mixture of oil, water and dust filtered out by the filter element, reducing the impact of human factors on the filtering efficiency of the system. The differential pressure gauge, differential pressure gauge, and electronic differential pressure indicator are used to guide the time to replace the filter element. The liquid level indicator is used to indicate the amount of mixed pollutants such as oil, water, and dust inside the filter (it can monitor the working condition of the internal automatic drainer and guide manual drainage).
