Description
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).
- The varied fiber diameter means extraordinary contaminant-holding capacity, maximum flow rate, and low costs per litre 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.
Quality and Bio-Safety Tests
- Meets USP Biological Reactivity, In Vivo, for Class VI-121 °C plastics
Effluent Quality Tests*
- Non-Fiber-Releasing
- Non-Pyrogenic per USP Bacterial Endotoxins (< 0.25 EU/mL)
* Per lot sample soak or rinse-up flush aliquots.
Reduced Operator Intervention and Exposure
The self-contained design of each Kleenpak filter means that operator intervention and exposure during filter installation and change-out are minimized.- Integrally molded inlet and outlet connections
- Maximum convenience and security
- Vent and drain connections with seal protected threads and precision molded valves
- Exceptionally simple and reliable operation
