Critical Advantages

1. 1.Anti-Channeling Design

   • Inward funnel eliminates nesting → 95%+ effective surface utilization.

2. 
   2.Chemical Immunity

   • PP: H₂SO₄ (≤60%), NaOH (any conc.)

   • PVDF: Concentrated HCl, solvents

   • CPVC: bleach solutions

3. 
   3.Energy Saver

   • 30% lower ΔP → Reduced pumping costs.

4. Fouling Resistance

   • Smooth surface + non-porous material prevents scaling.
