Air dryer importance

What is an air dryer?
An air dryer is a mechanical device that uses heat energy to reduce the moisture content of materials (mainly water or other volatile liquids). It vaporizes and escapes the moisture by heating, thereby obtaining a solid material with a specified moisture content. 

For industrial production, air compressor dryers are an indispensable investment, which can not only reduce the failure rate of air compressors, but also save a lot of energy consumption for enterprises.

If your product requires clean air, then a suitable dryer is essential.
This article will focus on the importance and common types of air compressor dryers.

Four advantages of air compressor dryers
1. Extend the service life of air compressors
During the operation of the air compressor, if the humidity of the inhaled air is high, water vapor will condense into liquid water during the compression process. Liquid water will damage the parts of the air compressor, such as emulsifying the lubricating oil, reducing the lubrication efficiency, and accelerating the aging and wear of the air compressor, thereby affecting the service life of the air compressor. The dryer protects the air compressor from water vapor erosion by removing moisture from the compressed air.

2. Improve air purity and meet production process requirements: Food, hospital, textile and other industries have high requirements for compressed air quality. Impurities such as moisture and oil will not only affect the quality and safety of the products produced, but may also cause failures and downtime in production. The dryer provides higher quality compressed air by removing impurities such as moisture, meeting industry needs and improving product quality.

3. Energy saving and consumption reduction, improving system efficiency: High humidity air is prone to scale formation, reducing equipment efficiency and increasing energy consumption. The air compressor dryer can effectively reduce the water content in the compressed air, reduce the temperature, and improve the energy efficiency ratio of the air compressor system. After the compressed air is dried, the loss during the transportation process is small, which helps enterprises save energy and reduce production costs.

4. Reduce maintenance costs: Compressed air treated by the dryer can significantly reduce the equipment failure rate and avoid wear and corrosion of the air compressor caused by impurities such as water and oil.

Air compressor dryers types
1. Adsorption dryer
Using the physical properties of the adsorbent, when the wet air passes through the adsorbent, the moisture is adsorbed and retained, thereby obtaining dry and clean air.


2. Refrigerated dryer
Use refrigeration technology to cool compressed air, lower its temperature, condense water vapor in the air, and then discharge it through the air-water separation device.


3. Combined dryer
The low dew point combined compressed air dryer developed by Airfler combines the advantages of cold dryers and adsorption dryers. Through reasonable pipeline connection and capacity matching, the advantages of both are maximized to achieve the best economic operation point and high-quality low dew point air.
