On the basis of introducing into and adsorbing the technology of America HANKISON and Germany ZANDER, we optimized and improved homemade desiccant air dryer, ensures its stable performance and reliable quality under the different working condition, achieving or over the quality of foreign identical product. So the quality of Hanfilter brand desiccant air dryer keep lead level, It has obtained two national technical patents by its advanced technology,stable quality,reliable control and ideal appearance. The one patent name: desiccant air dryer, patent No.: ZL 200820205277.8; the other patent name: desiccant air dryer controller, patent No.: ZL 200820205274.4.

1\Select unique adsorbent beads. The diameter is φ3.0mm. Bigger activated surface area, higher adsorption capacity and crush strength, longer use life

2\30% extra desiccant included to compensate for bed aging to ensure the stable pressure dew point.

3\Excellent adsorption tower design referred to aspect ratio of America HANKISON product, not only considered the transportation, but also ensured that the contact time is more than 5.2 seconds

4\Based on the adsorption characteristic of alumina and molecular sieve, the delamination technique designed by us, the air flows through alumina firstly to get initial drying, then gets further drying when flows through molecular sieve to achieve the air quality of low dew point.
