3. Manufacturing Process of Air Filtration Cartridges

Media Selection & Preparation
- Use of high-grade cellulose, polyester, nanofiber, or borosilicate material (sometimes ePTFE for HEPA), emphasizing ISO 16890 and EN 1822 compliance.
- Air permeability and particle retention validated by laboratory sample testing.
Pleating & Forming
- Automated CNC pleating machines create uniform folds (pleat height 20–60mm).
- The pleat count and depth enhance surface area, impacting both efficiency and pressure drop.
End Cap Assembly (Metal Forming or Polymer Injection)
- End caps are stamped/cast with galvanized steel or stainless steel, or produced by precision polymer injection molding for specialty cartridges.
- Epoxy or polyurethane adhesives bond media to end caps, ensuring high sealing integrity.
Core Reinforcement & Outer Mesh Wrapping
- Perforated tubes—aluminum or steel—used to reinforce structure and maximize air flow.
- Outer mesh (galvanized or stainless) prevents collapse and enhances physical strength.
Final QC & Performance Testing
- Each cartridge passes automated ISO/IEC 17025 standard testing: micron efficiency, pressure drop, burst resistance, and media integrity.
- Random batch sampling for life-cycle simulation, per ANSI/ASHRAE 52.2.
Packing & Traceability
- Laser-marked batch code for full traceability as per client/industry requirements.

Manufacturing flowchart: From media selection → pleating → end cap installation → reinforcement → QC testing.
Each phase is traceable and conforms to ISO 16890 and EN 1822.

Material highlight: Cartridge media options—cellulose/polyester blend (economic, robust), nanofiber (submicron filtration), PTFE membrane (chemical resistance), borosilicate glass microfibers (HEPA class), end caps in galvanized steel (cost-effective, corrosion protected) or 304/316 stainless steel (extreme corrosion, food-grade).
