Air and water don't mix when it comes to portable compressed air dryer systems.

A build-up of water, either liquid or gas, can wreak havoc on portable compressed air dryer systems including the equipment they power.

The list of potential problems are endless, but includes corrosion in piping and equipment, freezing of air lines (outdoor), pneumatic instrument and tool failure, fouling of processes and products, and more.

In portable compressed air dryer systems, air passes through a container filled with the water-absorbing (hygroscopic) media such as: activated carbon, silica gel, activated alumina, or other desiccant material. As water vapor clings to the desiccant, the material becomes saturated and will need to be replaced with new material.

Portable compressed air dryers make wonderful air dryers for any season because they don't rely on a reduced dew point like refrigerated dryers do. They can actually filter moisture in temperatures as cold as -100 degrees Fahrenheit.
