Flat Pleated Micropleated AMC Chemical Filter

Flat pleated micropleated AMC chemical filters are mainly used for the control of gaseous molecular pollutants in the air.

The product adopts a folded micropleat structure, which allows the chemical filter material to form a larger effective contact area. When the air passes through the filter material, the target pollutants come into contact with the active adsorption material, and the pollutants are controlled through physical adsorption or chemical adsorption.

Unlike HEPA filters, which mainly deal with air particles, AMC chemical filters mainly target gaseous molecular pollutants in the air.

Particulate matter control → primary efficiency filtration → medium efficiency filtration → HEPA/ULPA filtration

Gaseous pollutant control → Chemical filtration → VOC control → Acid gas control → Alkaline gas control

In MAU air handling units, chemical filters can be used in combination with primary effects, intermediate effects and other air treatment sections.

AMC Air Molecular Pollutant Control

AMC refers to air molecular pollutants, which mainly include acidic gases, alkaline gases, VOCs, ozone and some process-related molecular pollutants.

For clean production environments such as semiconductors, electronics, and optoelectronics, some molecular pollutants in the air may come from outdoor air, building materials, cleaning agents, solvents, and production processes.

The flat pleated micro-pleat AMC chemical filter can choose different chemical filter materials according to the actual type of pollutants.

Micro pleated folding structure

The flat folding structure is an important structural form of this product.

The chemical filter material is continuously folded to form multiple filter pleats, which increases the expansion area of ​​the filter material in the limited installation space, allowing the air to fully contact the adsorbent material.

Flat structure → Micro-pleat folding → Increase filter area → Air flow → Adsorption of molecular pollutants

The product is designed with a pleat pitch of 10–12 pleats/linear foot and can be configured based on product depth and usage needs.

Product structure

The product frame can also be made of aluminum, galvanized steel or stainless steel according to the actual application.

Activated carbon chemical filter media

The core of the chemical filter lies in the chemical filter material.

Aili industrial chemical filters use activated carbon and composite chemical adsorption materials, and configure different adsorption systems according to the types of pollutants.

The fine particle activated carbon used in the product can be coconut shell activated carbon, and the activated carbon parameters include 60-80 CTC, 30-60 mesh and other configurations.

Activated carbon adsorbs some gaseous molecules through a large specific surface area, and combines different chemical treatment materials to perform targeted treatment of specific pollutants.

Features

MAU air handling unit installation

Flat foldable micro-pleated AMC chemical filters are mainly used in the fresh air treatment section of MAU air handling units.

Typical air treatment process:

Outdoor fresh air→ Primary efficiency filtration→ Medium efficiency filtration→ AMC chemical filtration→ Surface cooling/heating→ Humidification/dehumidification→ Clean room

In actual projects, the chemical filter installation position and filter depth can be adjusted according to the MAU equipment structure.

Chemical filters and particulate filters undertake different air treatment tasks and can be combined and configured according to clean room air quality requirements.

MAU Chemical Filter Applications

Semiconductor clean room applications

In the semiconductor manufacturing process, process areas such as photolithography, cleaning, etching, and diffusion may involve different types of chemical substances. Therefore, the control of air molecular pollutants needs to be designed based on the actual process.

The flat foldable micro-pleat AMC chemical filter can be used at the fresh air end of the MAU, and the corresponding filter material is selected according to the type of pollutants.

Outdoor air → MAU pre-filtration → chemical filtration → temperature and humidity treatment → clean room

For semiconductor projects, 853, 147, 875 or composite chemical filter materials can be further selected based on pollutant detection data.

VOC air pollutant control

VOCs are one of the common contaminants in MAU chemical filtration applications.

VOCs may come from:

Outdoor air→Building materials→Coatings→Cleaning agents→Organic solvents→Technical materials

853 (2750) filter material is mainly used in the VOC direction and can be used for volatile organic pollutants such as toluene. It also has certain processing capabilities for SO₂, NO₂, ozone, sulfur oxides and boron.

Acid gas control

Acid gases include HCl, HF, H₂SO₄, SO₂, NO₂, etc.

875 (2751) filter material is mainly used for acidic pollutants, and can also be used for gaseous pollutants such as SO₂, NO₂, ozone and H₂S.

Acid gas → 875(2751) → Chemical adsorption → MAU fresh air treatment

Alkaline gas control

Alkaline gaseous pollutants mainly include ammonia, amines and NMP.

147(2752) filter material is mainly used for BASE alkaline gas direction, and can also be used for some VOC pollutants.

Alkaline gas → 147(2752) → MAU chemical filtration → Clean room fresh air treatment

Aili industrial flat chemical filter product parameters

The above dimensions support non-standard customization and can be adjusted according to MAU air volume, installation size and system allowable resistance.

Chemical filter selection

Chemical filter selection needs to consider both the pollutants and the air treatment system.

MAU air volume → Installation size → Filter depth → Pollutant type → Pollutant concentration → Temperature → Humidity → Allowable resistance → Use cycle

Customers can provide:

MAU air volume → filter size → installation depth → target pollutants → pollutant concentration → temperature → relative humidity → replacement cycle → installation method

Based on these parameters, the chemical filter type, filter thickness, filter size, and system resistance can be determined.

Service life

The service life of chemical filters is closely related to the actual pollution load.

Influencing factors include:

Pollutant concentration → Air flow → Temperature → Humidity → Filter material type → Filter material filling amount → Continuous operation time

The actual service life of the same filter material in different projects may vary, so the replacement cycle needs to be judged based on the on-site air quality and operating conditions.
