1、 The air filter has high filtration accuracy.  

It can effectively reduce the impact of dust on engine oil, oil content, and internal components. Using air filters with low filtration accuracy can lead to excessive dust and poor oil stability. Increasing the viscosity of lubricating oil and increasing the operating resistance of screw air compressors will inevitably increase the current when the exhaust volume is the same.

2、 The phenomenon of dust adsorption on the surface of oil increases, and the stability of oil decreases significantly.  

Increasing the throttle pressure will also increase the current under the same exhaust conditions. High filtration accuracy and low suction resistance are beneficial for energy conservation: In the case of high filtration accuracy, air filtration is beneficial for energy conservation. Low suction resistance is beneficial for energy conservation, while high air filter resistance simply wastes electrical energy.  

3、 Blocking moisture in the air is beneficial for energy conservation: during rainy seasons, due to high humidity, the probability of oil leakage is much higher because ordinary air filters do not have the function of blocking some moisture. Secondly, if the water content in the hydraulic system is too high, it will cause the viscosity of the oil to decrease and the oil will flow with the air。
