Customized Air Filter Cartridge 72x55

We are one of the professional customized air filter cartridge 72x55 manufacturers specialized in offering you high-quality customized air filter cartridge 72x55. If you want to buy one, please feel free to contact us.

72×55 is a high-efficiency pleated cylindrical filtration element engineered for industrial dust collection systems, HVAC air handling units, air compressor intakes, and ventilation equipment. This compact cartridge delivers exceptional particulate removal performance in space‑constrained applications.

The filter media is constructed from high-quality spun-bonded polyester non-woven fabric-a synthetic material that offers superior mechanical durability, moisture resistance, and chemical compatibility compared to cellulose or paper-based alternatives. Polyester media maintains its structural integrity in humid, oily, or chemically challenging industrial environments where paper elements would soften, collapse, or degrade. The pleated design maximizes filtration surface area within the compact cylindrical footprint, enabling high dust-holding capacity and extended service life.

is a globally recognized manufacturer and supplier of high-performance filtration solutions, specializing in custom heavy-duty industrial dust collector filter cartridges. Since 2003, our 26,000㎡ facility in Xinxiang has been home to over 70 dedicated professionals, giving us full control over design, material selection, production, and quality assurance. With more than 20 years of industry expertise, we deliver precision-engineered filtration products at factory-direct prices-not as a distributor, but as a true manufacturing powerhouse. 

We manufacture high-quality custom dust collector filter cartridges for cement, mining, pharmaceutical, metalworking, and general industrial applications, engineered to meet or exceed OEM specifications.

• 20+ Years of Industry Expertise: Over two decades designing and manufacturing heavy-duty dust collection filters for industries including cement, mining, pharmaceutical, and general manufacturing. Our engineering team understands the specific requirements of each industry.
• True Custom Engineering, Not Just Cross-Reference: We do not simply match dimensions-our experienced engineering team works directly with you to determine the optimal media (spundbond polyester, anti-static, PTFE membrane, etc.), pleat geometry, surface treatment, and seal/gasket type for your dust type and collector design.
• Vertical integration and lean manufacturing deliver heavy-gauge steel end caps, 5 mm+ thick inner support cages, and precision pleated media at factory-direct prices.
• Serving customers in over 120 countries while maintaining the responsiveness of a specialized manufacturer. When you contact Huahang, you're working with people who understand that every dust collection application matters.
• ISO-Certified Quality with Full Traceability: Our manufacturing processes are ISO 9001 certified, with rigorous quality control ensuring consistent, reliable performance across all products. Outer diameter (OD), height, and end cap configuration are verified before each shipment.

A: Standard polyester filters use depth filtration, where dust penetrates into the media fibers, increasing pressure drop and making cleaning difficult. Laminated polyester features a PTFE membrane bonded to the surface, creating surface filtration that traps dust on the surface for easy release, higher efficiency, and longer service life.

A: Yes. We offer full customization services including custom dimensions, filtration efficiency, anti-static treatment, oil-proof/water-proof treatment, and end cap configurations. Please provide your specific requirements or drawings for a custom quotation.

Q: How do I select the correct media treatment (anti-static, oil/water-repellent, PTFE)?

A: 

• Anti-Static: Required for combustible dusts to safely dissipate static charges to ground. Common in coal mines, grain handling, aluminum processing, pharmaceutical API dryers, and carbon black collection. Always verify ground connections in the collector.
• Oil/Water-Repellent: For applications with oil mists, machining coolants, or high humidity. Prevents media blinding and maintains airflow. Common in metalworking grinding, plastic extrusion, and cement plants where condensation may occur.
• For fine, sub-micron, sticky, or hazardous dusts. Provides near-HEPA efficiency (>99.99%), superior dust release, and long life. Common in welding fume, pharmaceutical packaging, toxic dust (lead, beryllium), and laser/plasma cutting smoke. This is typically the highest-cost and highest-performance option.
• For multi-hazard environments-industrial processes that produce both combustible dust and oil mist may require both anti-static and oil/water-repellent treatments.
