Real-World Usage

These filters are not just catalog numbers. They are used every day in:

  • New construction projects – road building, real estate developments, hospitals needing backup power

  • Events – concerts, sports stadiums, and large gatherings where gensets provide temporary electricity

  • Industries – mining, factories, power stations, and remote job sites

Demand is especially high in Egypt and Middle East oil fields, African mining sites, Chinese inland factories, and Iraqi standby gensets.

Common problems we’ve seen in the market include filters with weak metal supports that deform easily, filter paper tearing under stress, or poor packaging causing damage during transport.

Why Our Filters Stand Out

Our factory produces both 4N-0015 and 6L-4714 as mature products with stable stock.

  • Media: Ahlstrom filter paper (imported), giving high dust-holding capacity

  • Housing: 0.5 mm steel shells (others may use 0.3 mm, which deforms during shipping or operation)

  • Services: OEM supply, custom logo packaging, trial orders accepted

  • Market focus: supporting distributors in Africa and the Middle East where demand is strong

Conclusion

    • 4N-0015 protects the engine – keeping Cat 3406/3408 engines safe from dust and debris.

    • 6L-4714 protects the operator – ensuring clean cabin air in dusty job sites.
      Together, they extend equipment life and reduce costly downtime.
