What is a chemical filter

Chemical filteris used to remove gaseous molecular pollutants, chemical technology is the use of specially configured chemical materials adsorption of pollutants, and let the pollutant gas with the filter media in the chemical composition of the chemical reaction, the poisonous and harmful gaseous pollutants neutralized and oxidized to become harmless solid salts, so as to achieve the purpose of removing pollutant gases.

Principle of removing pollutants
Physical adsorption:
The process by which one substance is attracted to another and adheres to a surface. Activated carbon utilizes this principle to remove pollutants.
* Adsorption is a surface phenomenon;
* The higher the surface area the higher the adsorption capacity;
Disadvantage:Easy to saturate, in order to adsorb other substances, easy to release the adsorbed substances, the process is reversible.
Chemical reaction:filter media chemical reaction
The chemical reaction between the pollutant and the chemical substance in the adsorbent, thus achieving the purpose of removing the pollutant. The filter media of Esky Purifyis realized through this principle.
* The process is very specific and depends on the chemical properties of the adsorbent and the adsorbed material;
* the process is basically fast and irreversible;
* Can chemically oxidize toxic and hazardous gases into harmless solids.
 
Esky Purify's Chemical Filter Media
 
In the chemical filter is crucial is the selection of filter media, different brands of filter media, due to its composition, structure and performance differences, for the removal of gaseous molecular pollutants have different effects.

Esky Purify uses customized filter media formulations, which can be used in combination according to the needs, with SGS RoHS  EU CE and other test reports.

 
Chemical filter classification
 
1. Plate type chemical filter /application unit FFU

Plate-type chemical filter is a composite filter that efficiently removes airborne particles and gaseous molecular pollutants, widely used in AMC pollution and corrosion control projects, mainly used with fan filter unit (FFU), can also be used as a chemical filtration component of the air supply port or return port, the composite structural design of the filter material to give full play to the filtration function, according to the site environment of the gaseous molecular pollutants type and concentration, customized design of the filter material and framework. ，定制化设计过滤材料和框架材料，让空气更洁净。
 
2. W type chemical filter/application unit MAU/FFU

W-type chemical filter is a composite filter that efficiently removes airborne particles and gaseous molecular pollutants, which is widely used in AMC pollution and corrosion control projects, and can be applied in many ventilation system structures such as semiconductor industry, data room, pet hospitals, etc.;it can be equipped with different types of filter media to remove different kinds of AMCs, and the unique W-type structural design increases the contact area of the filter media and improves the filter media's The unique W-shaped structure design can increase the contact area of the filter media, improve the utilization rate of the filter media, and make the air cleaner.

Box chemical filter is a composite filter with high efficiency in removing airborne particles and gaseous molecular pollutants, widely used in AMC pollution corrosion control engineering, commonly used in higher concentration pollutant occasions, with the air conditioning unit;can be equipped with different types of filter media to remove different types of AMC, filter media dosage, long service life, so that the air is cleaner.


4. Cylindrical Chemical Filtration Module/application unit MAU

Cylinder chemical filtration module is a kind of composite filter with high efficiency to remove particles and gaseous molecular pollutants in the air, widely used in AMC contamination corrosion control engineering, commonly used in higher concentration pollutants occasions, with air conditioning units;can carry different types of filter media to remove different kinds of AMC, large amount of filter media, long service life, so that the air is cleaner.
 
5. V-Type Chemical Filtration Module/application unit MAU

The V-shaped chemical filtration module is used to load various types of dry filter media. Engineers used advanced fluid dynamics analysis tools to design the module structure into a V-shaped structure, which on one hand, can greatly improve the contact area and contact time between gaseous pollutants and the filter media, resulting in a significant increase in filtration efficiency;on the other hand, the module's streamlined air intake grill design makes it easier for airflow to enter and greatly reduces the resistance to achieve energy saving purposes.
 
These special designs ensure maximum utilization of the filter media during normal use. The modules are made of engineering plastics such as ABS, which are robust and inexpensive, and can be installed and used in a variety of frames and fixtures. Filling the modules with filter media should be done with sufficient vibration to ensure the uniformity of the filter layer.
