Importance

1. Avoid wear caused by dust or impurities, so as to ensure adequate protection of the screw rotor;
2. Able to provide oil products-an environment that is as clean as possible, so as to form sufficient protection for the oil;
3. Effectively filter out the corresponding dust and impurity particles, thereby increasing the service life of the engine;
4. Relatively clean air can reduce the noise of the inhalation process.

Working principle

The function of the air filter is to separate the liquid water and liquid oil droplets in the compressed air, and filter out the dust and solid impurities in the air, but cannot remove the gaseous water and oil.

1. The air generally contains harmful substances such as dust, rust, moisture, etc. The compressed air will have a coalescence effect when the first filter device is passed, that is, some particles will be condensed when passing through this channel, and larger The particles will stay on the filter screen, and the water will turn into larger water droplets after a long time of condensation of these small particles.

2. After that, the compressed air will enter the separation chamber. After entering the separation chamber, the air flow speed will naturally slow down. When the air circulation speed slows down, the particles flowing through the previous channel will gather again. There is a honeycomb-like water trap in the separation chamber, and the passing water mist will condense on this trap. The non-condensed water is water with impurities. The water with impurities will flow along the bottom of the device, and then when it reaches the position of the drainage device, the electric drain gate will discharge the water.

3. After filtering, you will get dry and clean compressed air that is dust-free, oil-free, and foggy. The clean air can also extend the service life of the pneumatic equipment.
