The Science Behind Compressed Air Desiccant Dryer

Compressed air systems and pneumatics are susceptible and always require high precision in regulating the air flow and filtering unwanted air particles to enter the airline. Water vapor is the number one factor that needs to be eliminated anywhere in the air system to avoid damage on pipes, airlines, air compressor, and air tools. When air is compressed, the by-products are always water vapor and dirt. Presence of water vapor anywhere in the airline results to condensation, which leads to more water build up and raises 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 Compressed Air Desiccant Dryer Work?

Desiccant materials by nature attracts water from its surroundings. When used in a compressed air system, it is by far the best addition to your air accessories. The way it works is nothing complicated. Desiccant dryers are frequently used as upstream moisture traps for air tools such as spray guns, sandblasters, plasma cutters, and other air tools. 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. Intended for end use, this inline air filter is designed to prevent 100% of water vapor and send the driest air possible towards the air tool. Once the beads are saturated, it turns to pink, which is a clear indication that the filter is ready for replacement.

Ubiquitous Lematec hosts some of the best compressed air filters in the industry. The ZN312-D-2 is one of the latest offerings in Compressed Air Dryers that use 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.
