What is the relationship between the efficiency of the high efficiency air filter and the air temperature?

The temperature of the oil and water contained in the compressed air affects the efficiency of the high efficiency air filter. Such as: when the temperature is 30 ℃, the oil flow through the filter when the 20 ℃ 5 times; when the temperature rises to 40 ℃, the oil flow through the filter is 20 ℃ when the 10 times. So the filter is generally installed in the compressed air system, the lowest temperature point.
