  • ⚛️  Description: This is a generic moisture filter, otherwise known as a humidity filter, water vapor filter or air dryer filter. This filter is used to reduce the moisture content of gas sample prior to being analyzed by a sensor, detector or meter. Removing water vapor content is important as most sensor technologies have cross-sensitivity to water vapor and a erroneous signal may be generated when taking measurements.  Very common to be used in combustion line setups, breath analysis or in humid sample environments. 
  • 📶  How does it work? Silica gel is a desiccant that can hold 30 to 40% of its weight in water. Water molecules stick to its surface, which is called adsorption. Each silica bead has many tiny interconnected pores, resulting in high surface area. These desiccant beads are dark blue in color and will change to a light clear pink when they have absorbed there maximum amount of moisture and need to be changed. Note when they start to turn pink they have usually about 40% life left in them so it is a personal preference how soon you change them also depends on how important it is that you get no moisture in your air line. 
  • 👫  Instructions: Connect the filter in line with the air supply line tubing. The filter is bi-directional so it does not matter which way it is connected. One end is the input the other is the output which is directed to the sensor.
