What is the purpose of the accessories of the air filter

The internal automatic drain and the external automatic drain in the air filter accessory are used to automatically discharge the mixture of oil, water and dust filtered by the filter element to reduce the influence of human factors on the filtration efficiency of the system.

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 contaminants such as oil, water, dust, etc. inside the filter (it can monitor the working condition of the internal automatic drain and guide manual manual drainage).
