It’s the nemesis of most air compressor applications, but there are ways to beat the moisture in your air compressor system.

If you’ve used air compressors to any extent, chances are you’ll be familiar with the gurgling and spitting that happens at the business-end of the machine as your compressor produces water as well as air. You may also be familiar with the way moisture can, for example, throw tyres off balance, ruin your paint spraying or sandblasting, or simply reduce the air pressure.

Water is bad news for compressed air, but where does it come from, and how can you get rid of it?

In all but the most arid places on earth, water is a frustrating by-product of compressing air. It occurs because the air your compressor sucks in includes water vapour. The act of compression causes the water vapour to heat up, filling your airlines with steam, which then condenses as it cools.

Filters will remove some of the moisture, but for precision applications like paint spraying, that frequently won’t be enough.


The power of dryers

Dryers remove far more moisture than filters. We operate two types:

Refrigerant dryers (almost counter-intuitively) accelerate the cooling process. They ensure more water vapour condenses quickly, where it can be collected and removed before it has the chance to reach the drills, sprays, guns and conveyors at the end of your air lines.

Desiccant dryers use ultra-absorbent materials to remove even more moisture, creating near-zero humidity by removing moisture to -70°C dewpoint.
