HDC II Filter Cartridges

Summary

Product Identification

HDC® II filter cartridges are constructed from pure polypropylene, featuring high-area pleated media. This new generation of HDC II filters incorporates a proprietary design that varies the fiber diameter continuously from coarse (upstream) to fine (downstream), significantly increasing dirt-holding capacity. This design allows for up to four times longer service life compared to other filters of similar appearance.

Removal ratings range from 0.6 µm (micron) to 70.0 µm absolute. All materials of construction are FDA-listed for direct food contact, and all components have been tested according to USP Class VI biological tests for plastics at 250˚F (121°C).

Operating Limits

• HDC "J" Series filters: Recommended maximum pressure differential is 75 psid up to 140°F (60°C).
• UNI CAP filters (HDC "J" Series configuration): Recommended maximum pressure differential is 45 psid up to 180°F (82°C).
• AB style filters: Recommended maximum pressure differential is 80 psid up to 122°F (50°C) and 60 psid up to 176°F (80°C).
• Warning: Using these filters for filtration at higher pressures or temperatures than recommended, or with fluids incompatible with polypropylene, can result in property damage, personal injury, and contaminated filtrate.
