Global OEM Choice for Asphalt Filtration
Asphalt mixing plants demand the most resilient dust filter bags due to extreme heat and abrasive aggregates. As the original equipment (OEM) supplier for international giants like SANY and Ammann, we provide the highest industry standards. According to 2025 data, we command a 46% supply share in the Chinese market, making us the leading provider of filter bags for asphalt globally.
Recommended Materials: Aramid (Nomex) FILTER BAGS is the Standard
Aramid (Nomex) is the benchmark material for filter bags for asphalt. We offer a comprehensive Aramid Filtration System featuring two specialized lines:
-
Solution-Dyed (Colored) Aramid Series: Enhanced thermal stability and easy fiber identification.
-
Natural (Ecru) Aramid Series: High-tenacity, pure performance for standard high-temp zones. These dust filter bags are engineered to withstand continuous operating temperatures up to 204°C (400°F).
Unique Design Advantages for Pulse Jet Systems
Our dust filter bags feature a reinforced Bag Top design to ensure a 100% leak-proof seal with the tube sheet. Given the high-velocity airflows in asphalt plants, we utilize heavy-duty seams and reinforced bottom construction to prevent premature wear. This robust structure ensures that each filter bag for asphalt provides a lower pressure drop and a longer service life.
Technical Tip: Managing Humidity and Acid Risks
Technical Tip: Asphalt production often involves moisture from raw aggregates, which can lead to hydrolysis in aramid fibers. If your plant processes materials with high moisture content, we recommend our filter bags for asphalt with PTFE membrane or water-and-oil repellent treatments. This barrier protects the dust filter bags from chemical attack and prevents dust caking on the surface.
