2.去除效率高
3.低壓損以降低風機的負載
4.低發塵量
5.低揮發性氣體
6.便於安裝要求質輕
7.針對要求的效率下去除容量要大即壽命長,以 減少更換次數也確保製程環境的潔淨度

Media
濾材:

※853(2750) – Used for removing VOCS, SO2, NO2, ozone, H2S. The 853 media is most effective for VOCS, and it has considerable capacity for common outdoor pollutants such as SO2, NO2, ozone, H2S. The 853 media is also very effective for removing boron (e.g., emission from conventional HEPA/ULPA filters)
※147(2752) – Used for removing ammonia and amines (nitrogen-containing organic compounds such as NMP, monoethylamine, morpholine, cyclohexylamine, dimethylamine, trimethylamine, diethylamine, HMDS and etc.)
※875(2751) Media - Used to remove acids such as HCI, HF, H2SO4, and is also very effective for removing SO2, NO2, ozone, H2S. This medial is better than 853 media.
※Both 147 and 875 media can remove VOCS. However, the life span of 147 media is reduced to 1/2 as compared to 853 media.


※853 (2750) 濾材 - 去除揮發性有機物、二氧化硫、二氧化氮、臭氧、硫化氫. 此濾材為最有效去除揮發性有機物的濾材, 同時它對一般室外的污染物有相當可觀的容量, 如二氧化硫、二氧化氮、臭氧、硫化氫. 此濾材對於去除硼也非常有效 (例如: 常用的HEPA及 ULPA濾網).
※147 (2752)濾材 -用於去除氨及胺類(含有氮的有機化合物, 如NMP, monoethylamine, morpholine, cyclohexylamine, dimethylamine, trimethylamine, diethylamine, HMDS 等)
※875(2751)濾材 - 對除二氧化硫、二氧化氮、臭氧、硫化氫也非常有效。【比853(2750)濾材效果還好】。
※147(2752)及875(2751)兩種濾材都可以去除揮發性有機物。然而,使用壽命與853(2750) 濾材相較減少了一半。

1.Four main techniques for controlling odor and gas contaminants: Gas Mask, Combustion, Ventilation and Removal.

2.Granular Media is used for controlling gas contaminants by Adsorption and Oxidation.

3.Chemical Filter can be used to remove molecular contaminants by Adsorption and Oxidation.

4.Adsorption: When gaseous or liquid molecules reach adsorbent surface but without any chemical reaction, the phenomenon is called physical adsorption or physisorption.

5.Sorption: When gaseous or liquid molecules reach adsorbent surface and happen chemical reaction, the phenomenon is called Sorption.

6.The bowling Point of adsorptive materials, vapor pressure and active are the main factor affecting the initial efficiency. The materials which boiling point higher than 100 ℃, will be in the liquid state at room temperature, and is easily to be adsorbed and condensed in the adsorbent surface.

7.In molecular contaminant system, initial contaminant removal efficiency is not depending on particle weight, size, total surface area or carbon activity. Two important parameters for determining initial efficiency is the total surface area of chemicals and absorbents.

8.The surface area increased when the dimensions of carbon are getting smaller. Particle size can be very small, even though it just becomes carbon dust. It also creates problems of escaping into the air, or due to packing tightly and causes high pressure drop.

9.Temperature also can affect adsorption efficiency. The higher the temperature the lower the adsorption efficiency. Moisture will occupy carbon’s adsorption surface, therefore adsorption efficiency is poor in wet weather (like rainy day).

10.For Material with small molecular weight or boiling point lower than ambient temperature, they cannot condensate as liquid; thus cannot attach on the surface of adsorbent, and they will be oxidized in air or substituted by other materials on the surface of adsorbent.

1. 控制臭味和氣體污染之的四種方式:防毒面具、燃燒、通風與移除。
2. 顆粒狀濾材用來控制氣體氣體污染物有兩種方式:吸附與氧化。
3. 化學濾網以吸附與吸著原理來移除氣體污染物分子。
4. 吸附:當氣體或液體分子碰到吸附體表面被抓著且無發生化學反應。
5. 吸著:當氣體或液體分子碰到吸附體表面被抓著且發生化學反應。
6. 被吸附物質的沸點、蒸氣壓及活性是影響初效率的主要因素。一般沸點大於100℃的物質室溫下的狀態為液態, 其蒸氣較易於吸附凝結在吸附劑的表面。
7. 分子性污染物系統,最初的污染物去除效率,並非由活性碳顆粒大小、重量及活性決定。決定初效率的兩個因素為吸收體及化學物的表面積。
8. 活性碳顆粒越細,其表面積越大。活性碳顆粒可以非常小,甚至為碳塵。此將會隨氣流溢散或因填充密實而產生高壓損等缺點。
9. 不同分子量的污染物均可競爭相同的吸附表面,由於溼氣會佔據吸附表面.通常潮濕的天氣下吸附效率會較差。溫度亦會影響吸附效率,溫度越高物理吸附能力越低。
10. 分子量小、沸點在常溫為氣態的物種,因吸附劑表面無法凝結液化,不易穩定附著在吸附劑表面,容易脫離氧化或被其他分子取代。

 
Typical Compounds of Class A, B, C, D (according SEMI F21-95)

The classifying method of AMC (Airborne Molecular Contamination) is the organization of SEMI (Semiconductor Equipment and Materials International) bases on SEMI F 21-95 to classify the AMC gaseous pollutants. Gaseous pollutant is including of Acids, Bases, Condensables and Dopants.
