HDC® II - J Series

HDC® II filter cartridges are constructed of pure polypropylene, high area, pleated media. This new generation of HDC II filters, unlike the original HDC filters and other polypropylene pleated filters, has incorporated a proprietary concept into its medium construction: varying the fiber diameter continuously to produce a pore size distribution from coarse (upstream) to fine (downstream). This unique construction permits more contaminants to be trapped in the outer layers of the medium, thus substantially increasing dirt-holding capacity. The finer inner layers are essentially unchanged from those of the original HDC medium, thus maintaining the absolute rating of the filter.

Relative filter life studies, both in the laboratory and in the field, have shown that this new construction increases service life as much as four times compared to other filters of similar appearance.

Removal ratings range from 0.6 µm (micron) to 70.0 µm absolute. Refer to Bulletin HDC 700 for more detailed information.

Operating Characteristics

The recommended maximum pressure differential for the HDC “J” Series filters is 75 psid up to 140°F (60°C) and 45 psid up to 180°F (82°C) for UNI CAP filters, and 80 psid up to 122°F (50°C) and 60 psid up to 176°F (80°C) for AB style filters.

Warning: Using these filters for filtration at higher pressures or temperatures than recommended, or with fluids incompatible with polypropylene, can result in property damage or personal injury and contaminated filtrate.

Sizes

HDC II "J" Series media are available in the UNI CAP configuration. UNI CAP series pleated elements are manufactured as 2 1/2" OD by 10, 20, 30, and 40 inch long filter cartridges. Elastomeric gaskets are attached to each end cap.

Sanitary (AB Style) elements are 2 3/4" OD by 10" single open-ended constructions with an O-ring piston seal at the open end. AB style elements are also available in 20, 30, and 40 inch lengths.

* Extrapolated value.

1 The test procedure used for liquid service rating is an adaptation of ANSI B93.31 - 1973, modified to determine the micron size above which particles are quantitatively removed.

2 Pressure drop in PSI per GPM water for a single 10" module. Multiply this value by the required flow to determine the total aqueous pressure drop. Next, for fluids other than water, multiply by viscosity in centipoise. If this calculated pressure drop is excessive, then divide this value by the number of 10" modules required to reduce this pressure drop to an acceptable level.
