Leveraging a professional technical team and extensive industry experience, we design and manufacture customized air filters and chemical media to meet clients’ application needs, industry sectors, and specific pollution-treatment requirements.
End-to-End Custom Air Filter Manufacturing Process
From initial requirements and custom design to sample testing, precision production, and final inspection, we manage every stage to deliver consistent quality and reliable air filters tailored to your project needs.
1. Demand Confirmation
Confirm the customer’s operating conditions, installation dimensions, filtration grade, temperature and corrosion resistance, filter media, and structural design. Collect drawings or old samples and verify operating environment parameters.
2.Technical Drawing & Quotation
Our engineers provide custom CAD drawings, optimise airflow, pressure drop, and the dust-holding structure, calculate costs, and issue a formal quotation to confirm specifications and lead time.
3. Sample Making & Test
Produce samples based on the finalized drawings and tested for filtration efficiency, pressure drop, air leakage, and dimensional tolerance. Customers conduct installation and testing; once approved, the mass-production standard is confirmed.
4. Raw Material Preparation
Prepare materials such as activated carbon, fiberglass, synthetic fibers, nonwoven fabrics, metal frames, sealants, and protective mesh.
5. Mass Production
Automated pleating to increase filter media area → frame bending and assembly → multi-layer media lamination → PU integral sealing and molding. Standardized production of panel, pleated, bag, and cylindrical/cartridge filters.
6. Finished Product Inspection
Re-inspect dimensions, appearance, filtration efficiency, and sealing integrity; conduct specialized leak testing for HEPA filters in the cleanroom and issue a test report.
7. Packaging & Shipment
Moisture-proof individual packaging and secure them on reinforced pallets. Neutral export packaging is available.
8. After-sales Service
Product batch traceability and installation guidance; rapid scheduling for repeat orders, with support for specification adjustments and urgent customization.
