The mesh can be applied during lamination or as a final backing layer. This enhances the media’s rigidity and overall service life.

   
5. Optional Impregnation (e.g., Activated Carbon):

   If the media requires gas-phase filtration properties, it may undergo an impregnation process with activated carbon or other chemical adsorbents. This creates activated carbon air filter media, designed to capture molecular contaminants.

6. Curing and Stabilization:

   The laminated or impregnated media may be subjected to heat treatment or other curing processes to stabilize its structure, enhance bonding, and ensure dimensional stability.

   
7. Precision Cutting and Slitting:

   Large rolls of finished filter media are precisely cut to customer specifications using automated CNC machining. This ensures accurate dimensions for subsequent filter assembly, minimizing waste and guaranteeing consistent product quality. This step is critical for filter media for sale.

8. Quality Control & Testing:

   Throughout the process, and especially at the final stage, rigorous quality control measures are implemented. This includes testing for filtration efficiency (e.g., using particle counters according to ISO 16890, EN 779, or ASHRAE 52.2), pressure drop, burst strength, thickness, basis weight, and fire retardancy (e.g., DIN 53438, UL 900). Only media that pass all stringent tests are approved for shipment.
