Company Overview
Hangzhou Hengke Filter Environmental Protection Co., Ltd. is a premier manufacturer specializing in industrial dust collector filter bags and bag cages. The company’s core team brings more than 20 years of deep expertise in technical textiles and air filtration, enabling Hangzhou Hengke to provide stable quality, exceptional filtration efficiency, and highly competitive pricing. Their flagship product portfolio includes high-performance PTFE needle felt, polyester needle felt, and fiberglass needle felt filter bags, all engineered to cater to the most challenging industrial environments. The company has established itself as a deeply trusted, long-term supplier to world-renowned cement conglomerates, including Conch Cement, Taiwan Cement, Heidelberg Materials (Heidelberg Cement), and CEMEX, demonstrating its ability to deliver at scale while maintaining rigorous quality standards.
Product Portfolio: High-Performance FMS Filter Bags
Hangzhou Hengke’s core product categories focus on industrial filter bags and cloth fabricated from advanced synthetic fibers such as PPS, Nomex, Fiberglass, and PTFE membrane. These FMS filter bags—where FMS stands for Fabric Material Systems—are designed for ultra-low emission targets and offer exceptional thermal stability and chemical resistance. Key capabilities include: operating continuously under extreme temperatures up to 200°C–260°C depending on material choice; resisting acid/alkali corrosion; and ensuring smooth dust cake release to maintain optimal airflow in baghouse systems. The company also provides bespoke solutions, matching fiber blends, weight, and surface treatments (e.g., PTFE coating, water & oil repellent treatments) to the specific gas chemistry and moisture levels of the client’s plant. This customization ensures that each FMS filter bag delivers the best balance of lifespan and performance for the application.
Technical Expertise & Customization
Hangzhou Hengke Filter distinguishes itself by offering tailored filtration solutions rather than mere standard products. Their technical team collaborates with clients to analyze flue gas composition, temperature fluctuations, and particulate characteristics. Based on this analysis, they engineer filter bags with optimized surface finishes such as PTFE membrane lamination, singeing, calendaring, or anti-static treatments. For instance, in cement kilns where clinker cooling and grinding processes generate high-temperature, abrasive dust, Hangzhou Hengke provides fiberglass felt bags with PTFE coating to resist thermal degradation and improve dust cake release. In coal-fired power boilers, where fine fly ash and acidic gases are present, they recommend PPS/PTFE blended felts for superior chemical resistance and filtration efficiency. This level of technical expertise positions Hangzhou Hengke as a best reliable supplier of FMS filter bags from China.
Application Scenarios
Hangzhou Hengke’s filter bags are extensively utilized in industrial dust collectors for cement kilns, steel smelting, coal-fired power boilers, and asphalt mixing plants. In each scenario, the company’s products help plants achieve ultra-low emission limits (e.g., ≤10 mg/Nm³) while reducing pressure drops and extending bag service life. The cost-effectiveness of their FMS filter bags is evident in reduced maintenance downtime and lower total cost of ownership. By implementing Hengke’s optimized filtration media, industrial plants can comfortably comply with local environmental regulations regarding PM2.5 and PM10 emissions, contributing to cleaner air and sustainable operations.
- Cement Industry: Filter bags for raw mill, kiln, and cooler dust collectors; proven performance in high-temperature, high-humidity environments.
- Steel Industry: Baghouse solutions for sinter plants, blast furnaces, and converter processes; resistant to abrasive dust and high temperatures.
- Power Generation: PTFE membrane bags for coal-fired boilers, ensuring low emissions even under variable load conditions.
- Asphalt Mixing: Polyester needle felt bags with oil-repellent treatment for efficient filtration of sticky fumes.
