Engineering summary from PDF text extraction for PY PAN 100kDa. Verify every value with the OEM datasheet.
Summary
Product identification
The PY (PAN 100kDa) is an industrial ultrafiltration spiral-wound element manufactured with a Polyacrylonitrile membrane. The element features a spiral-wound construction with either a tape wrap or a fiberglass hardshell (FRP). These elements are designed to offer an optimal combination of flux and rejection across a comprehensive range of molecular weight cut-offs (MWCOs).
Operating limits
Pressure
- Max Inlet Pressure: 116 PSI (8.0 Bar)

- Max. CIP Temperature: 122-131°F (50-55°C)
pH Parameters
- pH Range during Operation at 25°C Max.: 3.0-10.0
- pH Range during CIP Operation at 55°C Max.: 3.0-10.5
Peroxide
- Free Peroxide in Product During Operation: <3 ppm
- Peroxide as a Sanitizer at 25°C Max, pH 6-7, 10 minutes recirculation: 0.1%
Chlorine
- Free Chlorine During Operation: 0 Norm ppm (<0.1 Max ppm)
- Chlorine During CIP at pH 10.5 and 55°C: 150 Norm ppm (180 Max ppm)
Note: Maximum chlorine exposure for all elements is 30 minutes per day at the pH and temperature conditions listed above.

Membrane Area
Membrane area varies significantly depending on the element model and the feed spacer (available in 24, 31, 46, 65, and 80 mils). For example, the 1812TM element has membrane areas ranging from 1.3 to 3.1 sq. ft., while 8-inch elements like the 7940F and 8040F range from 178 to 379 sq. ft. See the official PDF for exact tabulated values for each element and feed spacer combination.
Recommended Element Cross Flow Rate
Recommended cross-flow rates vary based on element size and feed spacer configuration (24, 31, 46, 65, 80 mils). For 1.8" elements, rates range from 0.7 to 1.1 m³/hr (3 to 5 gpm). For 8" elements, rates range from 15 to 24 m³/hr (66 to 105 gpm). See the official PDF for exact tabulated values for each element size and feed spacer combination. Note: The recommended cross flow rate will be subject to differential pressure limitations and specific applications.
