How to Filter Water from an Air Compressor?

Published in Air Compressor Maintenance 1 min read

Filtering water from an air compressor involves several techniques to ensure dry, clean air for your tools and applications. Here's a breakdown of methods:

  • Location Matters: According to the reference, move your compressors to a less humid area. If you have conditioned indoor spaces, take your compressors inside.

  • Air Dryers:

    • Refrigerated Air Dryers: These dryers cool the air, causing water to condense and be removed. The reference mentioned using a refrigerated air dryer to reduce moisture.
    • Desiccant Air Dryers: Desiccant dryers use materials that absorb moisture from the air. The reference also mentioned that if you need a steam-free work environment, try a desiccant air dryer.
  • Water Traps/Filters: Install a water trap or filter in your air line. These devices collect condensed water, which can then be drained.

  • Regular Draining: Regularly drain the water tank of your compressor. Most compressors have a drain valve at the bottom.

  • Inline Air Filters: Use inline air filters to catch any remaining moisture and contaminants before they reach your tools.
