LFX-CMB™ Melt-Blown Polypropylene Depth Filter Cartridges

• Media and Construction: Multi-layer, graded-density melt-blown polypropylene (PP) depth-filtration media with rigid polypropylene core, cage and end caps. Fully thermal-bonded, binder-free construction minimises fibre migration, extractables and channeling. Outside-to-inside flow path enables progressive particulate capture, high void volume and extended dirt-holding capacity. Coreless configurations available on request for housings with integral support.
• Nominal Retention Ratings: 1, 3, 5, 10, 20, 25, 30, 50, 75, 100, 120, 125 and 150 µm nominal depth-filtration grades. 0.5 µm polishing grade available upon request (application-specific validation recommended).
• Nominal Lengths: 4.875 inch, 5 inch, 9.75 inch, 10 inch, 19.5 inch, 20 inch, 29.25 inch, 30 inch and 40 inch (124–1016 mm).
• Custom Length Options: Customisable non-standard lengths available on request for OEM system retrofits, legacy housings or specialised skid-based filtration systems (subject to feasibility and minimum order requirements).
• Outside / Inside Diameter: OD ≈ 2.4–2.5 inch (≈62–63 mm); ID ≈ 1.1 inch (≈28 mm).
• Dimensional Tolerances: Length ±1 percent or ±3 mm (whichever is greater); OD ±1 mm; ID ±1 mm.
• End Styles and Sealing Options: DOE (double open end) standard. SOE options available in 222 flat, 222 fin, 226 flat and 226 fin configurations. Elastomer options: EPDM (standard), Silicone, NBR (Buna-N) and FKM (Viton®) upon request.
• Operating Temperature Limits (Polypropylene Construction): Continuous service up to 80 °C; short-term excursions to approximately 90 °C depending on fluid chemistry and elastomer selection.

• Industrial Water Treatment: Removal of colloidal iron, sand, rust, scale and suspended particulates from cooling-water, rinse-water, boiler-feed pretreatment and utility loops; stabilises system cleanliness and protects downstream equipment.
• Chemical Processing: Clarification of acids, alkalis and compatible solvents using gradient-density PP media that supports stable recirculation, transfer operations and batch consistency across general chemical manufacturing.
• Inks, Paints and Coatings: Capture of agglomerates, undispersed pigments and contaminants to maintain viscosity stability, improve finish quality and prevent nozzle or equipment fouling.
• Food and Beverage Utilities: Prefiltration of process water, CIP fluids, syrups and sugar solutions; food-contact-compliant variants available where required for auxiliary process streams.
• RO and UF Membrane Pretreatment: High-capacity particulate protection for downstream membrane systems, reducing fouling, stabilising ΔP and extending membrane service intervals.
• Electronics and Microelectronics Support Systems: Filtration of cooling-water, utility DI water, equipment rinse lines and non-critical process streams within semiconductor and photovoltaic facilities.
• General Plant Services: Side-stream filtration for cooling towers, wash systems, plating operations, metal-finishing utilities and other industrial service-water loops requiring robust, cost-efficient particulate removal.
