HDC® II Junior Style Filter Cartridges

Increased Dirt-holding Capacity
and Filter Service Life

High dirt capacity pleated polypropylene filters constructed with a proprietary technique: varying the fiber diameter instantaneously and continuously to produce a pore-size distribution from coarse (upstream) to fine (downstream) while maintaining constant void-volume throughout the depth of the filter medium. This unique construction means that more contaminants are trapped in the outer and inner layers of the medium, thereby substantially increasing its dirt-holding capacity, and the service life of the filter.

Sealkleen and Junior HDC II style filters are available in absolute removal ratings from 0.6 μm to 40 μm. The all-polypropylene construction of these filters make them compatible with an extremely wide range of fluids. Cartridges with a P option are optimized for pharmaceutical applications.

Typical Liquid Flow Rates for SLK7002 and MCY4463 Styles

 

Note: Differential pressures are for liquids with a viscosity of 1 cP. Differential pressures for liquids at other viscosities can be conservatively estimated by multiplying the indicated differential pressure by the viscosity in cP. To obtain the total pressure drop of a complete filter assembly the housing pressure drop must be added. Please refer to the relevant housing literature or contact Pall.

Sterilization

• Steam-sterilizing Temperature Up to 140 °C  in situ or autoclave

¹Per lot sample soak or rinse-up flush aliquots

Sealkleen Style

• Single open-ended 57 mm (2.25 in.) diameter element (excluding flange)
• Incorporates a patented sealing arrangement that eliminates any chance of fluid bypass via the seal, from the upstream side of the filter element to the downstream side
• The housing elastomeric O-ring is placed on a special flange, which is an integral part of the element outlet end cap
