Zhengzhou Kelin Water Purification Material Co., Ltd offers a wide variety of activated carbon, activated alumina and other water filter materials. It has been used as an air and water purifier since antiquity. Today, it is widely used in home, commercial, and industrial applications ranging from personal protective devices to mercury scrubbing and biogas removal.

Merthod of Use
1. Do not open the packing before use, in order to avoid moiture absorption, affect the use effect;
2. DEPTH of activated alumina desiccant is suitable for drying, conditions of use to pressure is grteater than 5kg/cm2;
3. After Activated alumina desiccant used a certain period of time, the adsorption performance will gradually decline, should through the regeneration, removal by adsorption of water, so that repeated used of gas in regenerative operation(with lower than dry homework or identical pressure of dry gas; with higher than dry operations or identical temperature of dry gas; after temperature of wet gas; after decompression of wet gas);
