Karcher WD/MV HEPA Cartridge Filters | Dust Control Experts

Raw Material Inspection → Certified glass fiber & polyurethane sourced and tested per ISO/IEC 17025.
Core Media Formation → Micro-glass fiber is pleated and heat-set using precision CNC-guided pleaters for maximum dust-holding area.
End Cap Molding → Polyurethane end caps are injection-molded for seal integrity and corrosion resistance.
Assembly & Sealant Application → Robotic assembly lines guarantee uniformity.
Testing & Certification → Every filter batch tested for pressure drop, particulate retention & leakproofness, according to EN 1822:2019 & ISO 29463 protocol.
Packing → Vacuum-sealed and anti-static packaging for ensured long-term storage.

Key Advantages: CNC pleating increases uniformity; injection-molded polyurethane offers better resistance in high-humidity or corrosive industrial environments (oil & gas, food, metallurgy).

Technical Advantages: Why Choose This Filter?

High Filtration Efficiency: 99.97% @ 0.3μm (H13 grade), surpassing most generic filters.
Durable Materials: Advanced micro-glass fiber media, anti-corrosion polyurethane caps withstand harsh chemicals, acids, and moisture.
Low Pressure Drop: Reduced energy consumption by 11–17% compared with legacy pleated filters (independent benchmark tests 2023).
Longer Service Life: 30–40% longer interval between changes (12–24 months typical).
International Certification: Fully conforms to ISO 9001:2015, EN 1822, CE for QA, with batch traceability.
