The Science Behind Compressed Air Desiccant Dryer

Compressed air systems and pneumatics are susceptible and always require high precision in regulating the airflow and filtering unwanted air particles to enter the airline. Water vapor is the number one factor that must be eliminated anywhere in the air system to avoid damage on pipes, airlines, air compressors, and air tools. When air is compressed, the by-products are always water vapor and dirt. The presence of water vapor anywhere in the airline results in condensation, leading to more water build-up and raising the dew point. When the compressed air is not filtered, corrosion and dirt can build up on air accessories, tools, and pneumatic instruments.

How Does a Compressed Air Desiccant Dryer Work?

Desiccant materials by nature attract water from their surroundings. Desiccant dryers are frequently used as upstream moisture traps for air tools such as spray guns, sandblasters, plasma cutters, and other air tools. When used in a compressed air system, it is the best addition to your air accessories. The way it works is nothing complicated. As compressed air travels through the airline and passes the compressed air desiccant dryer, the Silica Gel beads absorb the water vapor from the compressed air. This inline air filter is designed to prevent 100% water vapor and send the driest air possible towards the air tool. Once the beads are saturated, it turns pink, which indicates that the filter is ready for replacement.

Ubiquitous Lematec hosts some of the best-compressed air filters in the industry. The Le Lematec ZN312E-2 Desiccant Air Filter is one of the best offerings in Compressed Air Dryers which uses desiccant filters that work well even in the lowest dew-point. It is replaceable and guaranteed to remove 100% of moisture from the airline for best use.
