Product Identification

LOFTOP Absolute Filter Cartridges

LOFTOP absolute filter cartridges are engineered for demanding filtration applications requiring high purity. They are constructed from 100% high purity polypropylene micro fibers, formed by a meltblown process that eliminates the need for binders or additives.

General Features

• 100% pure Polypropylene
• No added adhesives
• Excellent chemical compatibility
• Biologically and chemically inert
• Controlled pore size
• Suitable for steam sterilization and autoclave
• Efficiency rating ß-ratio 5000
• Open pore structure
• High structural stability
• High dirt load capacity
• No fiber release
• DOE cartridges and SOE cartridges with FPM O-ring adapter are silicone-free.

Typical Applications

• Pharmaceutical: Protection of membrane cartridges, filtration of extracts.
• Electronic: Pure water, DI-water (pre-filtration), R.O. water (pre-filtration), photo resins, acids, bases.
• Film and Photo: Photo resist resins, film lacquers, developer, emulsion, magnet dispersion.

    • 4 (SOE 222 O-rings/flat)
    • Viton O-rings available for types 2, 3, 4.

• Sealing Materials:
  • Version G: Polypropylene
  • Versions 2, 3+4: Silicone rubber (standard), Viton (optional)

Performance Data

• Efficiency: > 99.98% (ß-ratio 5000). Filter efficiencies in µm at given ß-values are tabulated in the official PDF.
• Dirt Holding Capacity: LOFTOP cartridges utilize a graded fiber structure for high dirt loading. Maximum capacities are in the outer layers to prevent blinding. Tabulated values for Dirt Holding Capacity (g/10") are available in the official PDF. Tests were performed in water at 20°C with 7.5 l/min/10” flow rate, using coarse test dust at 1.2 g/l inlet concentration to a final ∆P of 2.7 bar.
• Recommended Flow Rates: Filtration efficiency and particle holding capacity are dependent on viscosity, filter efficiency, and flow rate. Recommended flow rates (l/min/10” length) for various viscosity levels are detailed in the official PDF.
• Pressure Drop (∆P): Pressure drop-flow rate characteristics for water at 20°C are detailed in the official PDF. Flow rate is stated as flow per 10” length. For multiple length cartridges, flow rate is proportional but should not exceed 4500 l/h.
