Screw air compressor needs to be connected to post-processing equipment dryer, why? Because there is a lot of water vapor in the air, if the water vapor directly enters the host after passing through the air compression system of the screw air compressor, it will affect the quality of the compressed air of the air compressor. In serious cases, it will also cause various problems of the air compressor equipment, such as rust, scale, etc. in the air pipeline. If the lubricating fluid in the pneumatic tool accidentally seeps into the water vapor, the effect of the lubricating fluid will be affected, the maintenance times will be increased, and the service life of the equipment will be reduced. Some products will be damaged if they enter the water vapor during operation, such as during painting.

There is no dryer connected. After the air is compressed, there is excess water in the air. The compressed air has heavy moisture, and the quality of the products produced will have problems. If a filter is installed behind the air compressor, you can see the overflow of water drops. After the air is compressed, the temperature will be high. After transmission, the temperature will be reduced, and liquid water will condense, which will have a great impact on users. Therefore, it is necessary to dry before transmission. Generally, screw air compressor is only suitable for compressing gas. Before leaving the condenser, a dryer should be added to prevent liquid refrigerant from flowing into the compressor, so as to prevent "cylinder knocking".

You should know that dryers are mainly divided into two categories: adsorption dryers and refrigeration dryers. The common role of both dryers is to remove water from the air compressed by screw air compressors. According to the requirements of enterprise users, for example, the compressed air should not take up water. The dryers must be equipped. Some users have no requirements for gas, but for the sake of normal operation of the equipment and cases, It is recommended that the user equip the air compressor with a dryer.
