So your humidity indicator says there’s moisture present in your air source. Now Once you’ve identified it, you need to remove it don’t you? DeVilbiss has you covered there, too. Their desiccant snake installs in-line — just like the indicator — and will remove the humidity. It also has built-in dirt and oil aerosol filters as well. And it’s compatible with HVLP and conventional systems.
Best of all, it streets for around $20 — a lot less than a full moisture removal system. For full protection, you could run two humidity indicators: one before and one after the snake to make sure it’s doing its job.
