HDC® II Membrane in Kleenpak™ Capsules for Liquid Applications

HDC II Filter Medium

• The HDC II filter medium is comprised of high-performance pleated cartridge with polypropylene filter medium.
• Medium is produced by varying the fiber diameter continuously to provide a pore-size distribution from coarse (upstream) to fine (downstream) while maintaining constant void-volume throughout the depth of the filter medium.
• The varied fiber diameter means extraordinary contaminant-holding capacity, maximum flow rate, and low costs per liter of filtered fluid.
• The fixed pore structure means that contaminants will not unload under  variations in flow or pressure differential, and fibers will not migrate or become dislodged to contaminate process fluids.

Clean and Robust Design

• The highest possible security against filter bypass is ensured, even under conditions of pulsed flow
• High-strength design allows multiple autoclave cycles for extended use and maximum filter economy.
• Polypropylene outer shell is designed to provide long-term assurance of pressure and temperature ratings.
• Internal hold-up volume and dead space is minimized for maximum product recovery.
• A total absence of glues, binder resins and surfactants results in very low filter extractables and extremely clean filtrate
• All filter materials of construction have met the specifications for USP Class VI biological tests for plastics at 121 °C and meet FDA requirements for food contact use 21 CFR parts 170-199

Quality and Bio-Safety Tests

• Meets USP Biological Reactivity, In Vivo, for Class VI-121 °C plastics

Effluent Quality Tests*

Steam Autoclaving

Cumulative Autoclave Time 4	50 hours at 140 °C

⁴ Laboratory tests (1-hour cycles) establish multi-cycle resistance. Filters should be qualified in actual use.

WARNING: Kleenpak filters must not be steamed in situ by passing steam through under pressure.
