QXL™ Polypropylene Filter Series

QXL Polypropylene Filter Series

Absolute Rated Filtration for Inks, Slurries and Coatings

With its extra-loft, extra-life depth filter configuration, the QXL is designed for the filtration of industrial solutions containing agglomerated particles and gels or with high viscosity. Consistent absolute retention performance is achieved throughout the pleated, serialized microfiber matrix. The state-of-the-art optimized structure provides significantly higher flow rates and throughputs than cylindrical melt blown filters.

Filter Features– Benefits

    • Hybrid pleated depth construction combines graded pore structure with high surface area.
    • Constructed entirely of polypropylene – Compatible with a broad range of solutions and chemicals
    • Optimized pleat configuration – Provides the ideal combination of retention, flow rate and throughput
    • Available in absolute ratings from 0.45 μm to 40 μm. Excellent gel and agglomerated particle retention reduces defects
    • Available in common end cap configurations – Retrofits easily into most filter housings
    • FDA listed materials of construction
    • Meets USP Class VI Biological test for plastics
