Supplier's note

  1. Technical Breakthroughs:

    • The polyester fiber paper core enables 20% faster flow rates than traditional cellulose cores while maintaining filtration efficiency.
    • Chemical-resistant Pro Model housing exceeds industry standards (ISO 9001), ensuring safe use with chlorine and saltwater systems.
    • The stackable cylindrical design reduces storage space by 30% compared to bulky filter systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential pools (e.g., backyard setups) with standard water chemistry.
    • Advanced Model: Perfect for commercial pools (e.g., hotels) needing higher flow rates and UV resistance.
    • Pro Model: Designed for industrial or heavily chlorinated systems, where tripled chemical resistance and 80 PSI tolerance ensure reliability under extreme conditions.

With the Pro version’s chemical resistance, you can safely handle aggressive sanitizers, while its high-pressure tolerance supports large-scale filtration systems. Pair this with the polyester core for uninterrupted operation in sunny outdoor environments.
