Moisture Indicators
Color Changing
In dry air systems, there is a critical need to monitor the air to make sure a dry condition is present.
High moisture levels can cause malfunctions of equipment or loss of products being processed. Wet
compressed air can be very harmful in many applications.
PUREGAS moisture indicators provide an easy, inexpensive way to monitor a dry air system. The
moisture indicator can be installed anywhere in the system after the air dryer, or at point-of-use. A
color change from blue to pink gives a visual indication of rising moisture levels.
