PneumaticPlus SDD450-N04F in-Line Desiccant Air Dryer 1/2" NPT - Metal Bowl w/Large Dome, 1 Quart Blue Desiccant Bead

PneumaticPlus SDD450 Series, The compressed air flow path through the dryer assures desiccant packing and maximum utilization of the desiccant’s adsorption qualities. The compressed air enters the dryer inlet port and is dispersed through a 10 micron polypropylene element (Dispersion) for removal of particles. The air is then distributed uniformly through the full desiccant bed to the bottom of intake tube. The intake tube is protected by a 40 micron polypropylene element. As the desiccant adsorbs moisture, a dramatic and highly visible color change from dark blue to light pink is evident. The color change works its way through the desiccant as the adsorptive qualities of the desiccant are diminished. Once the color change is visible through the Large Flat Sight Glass, the full desiccant bed has reached its maximum drying capacity and must be either changed or regenerated. Dry air exits through the inside diameter of the intake tube and out the outlet port of the unit.

• Adsorption means the attraction of a substance – the adsorbate – to, and its subsequent accumulation on, the surface of a solid material–the adsorbant–which is caused by physical forces of attraction. Adsorbants are substances which are permeated by a large number of very fine pores which give rise to large internal surface area. This, in turn, determines the adsorption capacity of the adsorbant, since a large internal surface can accommodate more adsorbate.
