What is activated carbon fiber felt?
Activated carbon fiber felt, commonly shortened to ACF felt, is a flexible fibrous activated carbon medium. Unlike a carbon-bearing nonwoven composite, the adsorptive material is formed as a felt that can be supplied in rolls or sheets, layered, cut or converted into application-specific filter components.
Looking for polyester fibers carrying powdered activated carbon? See PET-based activated carbon filter media. That material has a PET fiber support; it is not ACF felt. Check the material specification rather than selecting by a similar name or appearance.
Typical applications and conversion formats
ACF felt is used where a filter design requires a flexible adsorption layer for VOC or odor control. Project discussions can cover roll or sheet supply, cut layers and converted components after the operating conditions and filter structure are reviewed.
- Industrial VOC and odor-control filter components
- Layered media for air-purification assemblies
- Cut parts for cartridges and compact filter modules
- Custom roll width, thickness and converted size
ACF felt or carbon sandwich nonwoven?
ACF felt is a fibrous activated carbon medium. Activated carbon sandwich nonwoven instead has activated carbon between supporting nonwoven layers. They are different material structures rather than interchangeable names. Compare the target pollutant, airflow, installation space and downstream conversion before choosing. See the activated carbon media comparison guide.
Information needed for ACF felt selection
Send whatever information is already available. A drawing or sample photo is also helpful when the felt will be converted into a custom filter component.
Matching an existing felt specification
Include “activated carbon fiber felt (ACF felt)” and any existing grade or model reference in your RFQ. If a treatment is specified, send its name and the existing datasheet, together with the target gas or odor and any test requirement. A match in color or thickness does not confirm the grade or treatment. These details need to be reviewed before a material is confirmed.
ACF fiber-grade reference
The SY values below describe activated-carbon-fiber raw-material grades, not finished felt SKUs or a promise that every grade is available in every thickness. Match an existing grade or performance requirement to a proposed finished felt model before ordering.
- SY-1000
- 900–1000 m²/g; iodine 850–900 mg/g; benzene adsorption 30–35 wt%; methylene blue 150 ml/g
- SY-1300
- 1150–1250 m²/g; iodine 1100–1200 mg/g; benzene adsorption 38–43 wt%; methylene blue 180 ml/g
- SY-1500
- 1300–1400 m²/g; iodine 1300–1400 mg/g; benzene adsorption 45–50 wt%; methylene blue 220 ml/g
- SY-1600
- 1450–1550 m²/g; iodine 1400–1500 mg/g; benzene adsorption 53–58 wt%; methylene blue 250 ml/g
- SY-2000
- 1800–2000 m²/g; iodine 1700–1800 mg/g; benzene adsorption 70–80 wt%; methylene blue 300 ml/g
These raw-fiber grade values do not replace the finished felt series specifications above. Test methods and the finished-product grade mapping must be confirmed for the proposed model.
- Target VOC or odor source
- Required thickness, plus roll width and length or sheet dimensions
- For cut parts: a drawing with dimensions, tolerances and quantity for each size
- Operating airflow and installation format
- Need for cutting, layering or cartridge conversion
- Trial quantity and expected order quantity
OEM and conversion support
Junkang supports ACF felt roll or sheet supply and custom component development. Available project discussions include cut-to-size conversion, layering and ACF cartridge development, subject to the selected material, drawing and factory feasibility confirmation.
