Acrylic Filter Bags
Leading Dust Filter Bag Manufacturers & Suppliers in China

PRODUCT DESCRIPTION
Maximize uptime and filtration precision with Yuanchen’s high-density Acrylic needle felt. Unlike standard synthetic fibers, our Homo-polymer Polyacrylonitrile is built to resist the chemical breakdown (hydrolysis) that often plagues power and smelting plants. By maintaining fiber integrity in the presence of moisture and sulfur oxides, these bags ensure your facility stays compliant with emission standards without frequent, costly replacements.
Technical Advantages
-
Defeating Hydrolysis in Wet Conditions: This fiber’s molecular structure is inherently non-reactive to water. In applications like non-ferrous smelting or industrial drying, where moisture is a constant byproduct, Acrylic stays strong while others become brittle and fail.
-
Superior Flue Gas Compatibility: Filtering gases with high SOx concentrations requires a media that doesn’t surrender to acid dew point corrosion. Acrylic’s robust chemical backbone provides a reliable shield, maintaining tensile strength across demanding filtration cycles.
-
Advanced Dust Release Technology: By utilizing a specialized singeing and calendering process, we create a smooth “skin” on the felt. This reduces the energy required for pulse-jet cleaning and prevents fine particulates from becoming permanently embedded in the media.
-
Precision Engineering & Fit: Every bag is fabricated to exact OEM specifications. Reinforced triple-stitched seams and customized top/bottom configurations ensure a bypass-free seal within your dust collector housing.
-
Enhanced Emission Control: When paired with our proprietary PTFE surface coating, these bags can achieve emission levels lower than 5mg/Nm³, meeting the most stringent global environmental protocols.
Applications
Strategic deployment of Acrylic filter bags is most effective in the following sectors:
-
Non-Ferrous Smelting: Reliable recovery of copper, lead, and zinc dust in acidic exhaust streams.
-
Asphalt & Aggregate Plants: Managing the heavy moisture and varied temperatures of mixing towers.
-
Chemical Production: Filtration in processes where organic solvents or acidic catalysts are present in the gas phase.
-
Waste-to-Energy Cooling Zones: Used in the secondary stages of flue gas treatment where temperatures have stabilized.
-
Coal-Fired Industrial Boilers: An excellent choice for boilers operating with high-moisture fuel sources or specific desulfurization setups.
