1.Anti-Channeling Design
Inward funnel eliminates nesting → 95%+ effective surface utilization.
2.Chemical Immunity
PP: H2SO4 (≤60%), NaOH (any conc.)
PVDF: Concentrated HCl, solvents
CPVC: bleach solutions
3.Energy Saver
30% lower ΔP → Reduced pumping costs.
Fouling Resistance
Smooth surface + non-porous material prevents scaling.
