Industrial Pre-Filter Media – Product Details

I. Product Overview

This series of industrial pre-filter media is manufactured from environmentally friendly raw materials using advanced production technology. It is specifically designed for industrial air filtration systems and is widely compatible with injection molding machines, air compressors, fresh air systems, and various mechanical filter units. The product provides an efficient and reliable pre-filtration solution, serving as the first line of defense in air purification systems.

II. Core Function Positioning

As a key pre-filtration component in air filtration systems, this filter media is primarily responsible for coarse filtration at the initial stage. It effectively captures large particulate contaminants, protecting downstream high-efficiency filters such as HEPA and activated carbon filters. This significantly reduces wear on secondary filters, extends the overall service life of the filtration system, and lowers long-term maintenance and operating costs.

III. Core Materials

The filter media is made from low-melting-point, break-resistant eco-friendly polyester fibers, offering excellent wrinkle resistance, elasticity, and dimensional stability. It also features outstanding electrical insulation, light resistance, and abrasion resistance, with no risk of mildew or insect damage. The material is resistant to weak acids and alkalis, making it suitable for complex industrial environments.

Produced through a melt-blown spinning process, the ultra-fine fibers form a dense, thickened three-dimensional network structure. The manufacturing process involves zero chemical additives, resulting in an odorless and non-toxic product with a clean, bright white appearance that complies with environmental and safety standards.

IV. Manufacturing & Process Features

• Hot-Air Double Carding Technology
  Utilizing German-imported equipment, fibers are laid in a three-dimensional interlaced structure through a multi-layer progressive density process. This ensures uniform fiber distribution and effectively eliminates fiber breakage common in traditional needle-punch processes. Tensile strength is enhanced to ≥80 kPa, providing superior structural stability.

• Low-Temperature Thermal Bonding
  Fiber bonding is completed under precise temperature control between 110–130°C, with no emission of formaldehyde or other volatile organic compounds. VOC emissions are strictly controlled below 0.01 mg/m³, ensuring maximum safety for operating environments.

• Hydrophobic Treatment
  A nano-scale hydrophobic agent is applied, achieving a water contact angle greater than 120°. This delivers excellent water and moisture resistance, maintaining structural integrity and stable filtration performance even under extreme conditions with up to 100% humidity.

V. Filtration Performance

The filter media demonstrates high interception efficiency for particles ≥10 μm, including dust and suspended particulates. Filtration efficiency reaches ≥92%, effectively purifying intake air and ensuring clean airflow for downstream equipment and precision systems.

VI. Key Product Advantages

1. High Filtration Efficiency
   The multi-layer gradient structure enables dual-mode filtration through surface interception and deep-layer adsorption, delivering higher efficiency and faster filtration rates than conventional filter media.

2. Excellent Air Permeability
   Optimized gradient pore distribution increases the effective airflow area to 85%, reducing air resistance while maintaining filtration efficiency and ensuring normal airflow and heat dissipation for equipment.

3. High Dust-Holding Capacity
   The three-dimensional dust-holding structure provides a dust capacity of up to 200 g/m². Resistance increases slowly during operation, extending service life and achieving a balance between low pressure drop and high dust collection efficiency.

4. Cost-Effective Performance
   The thickened, high-density structure offers moderate flexibility and strong adaptability to multiple applications. It supports efficient reuse, delivering excellent economic value while reducing overall filtration consumable costs.

5. Safe & Environmentally Friendly
   Certified to ROHS standards, the product is manufactured with zero chemical additives and is odorless and non-toxic, posing no harm to humans or the environment and fully complying with green manufacturing requirements.

VII. Maintenance & Replacement Guidelines

• Washable Type
  Designed for excellent wash resistance, the filter media withstands repeated cleaning without fiber shedding. It features high water permeability and low water resistance, effectively removing contaminants during cleaning. Recommended cleaning is performed with low-pressure water below 0.3 MPa at temperatures under 40°C, followed by natural air drying. Filtration efficiency recovery exceeds 95%, allowing multiple reuse cycles.

• Disposable Type
  Replacement is mandatory when the final pressure drop reaches twice the initial resistance, or after continuous use for six months, to ensure stable and effective filtration performance.
