Suction dryer, also known as adsorption dryer, removes moisture from compressed air through the principle of pressure swing adsorption. It adopts a dual tower structure, with a desiccant (such as activated alumina) inside the tower. When compressed air enters the tower and comes into contact with the desiccant, it uses the principle of pressure swing adsorption to adsorb water, thereby reducing the dew point temperature of the compressed air. The dew point temperature of the suction dryer can reach below -40 ℃, ensuring the drying effect of compressed air.
Filters are used to remove pollutants such as oil, dust, and odors from compressed air.
Drying machines are mainly used to remove moisture from compressed air.
