A Cost-Effective Choice for Final Particle Removal and Pre-filtration in Liquids, Air and Gas - Including Reliable Protection of Final Membrane Filters
The Poly-Fine II pleated filter cartridge element is a high area, all-polypropylene depth filter cartridge frequently used in a wide variety of applications. These filter cartridges have broad chemical capability and are constructed of ultra-thin, proprietary melt-blown filter media that is intended for particle removal, excluding oils.
Filter Size
0.8 cm²
Why choose Poly-Fine II pleated filter cartridges?
The highly consistent pore structure with narrow pore size distribution and removal ratings ranging from 0.2 to 100 µm makes these filter cartridges ideal for capturing non-deformable contaminants, particularly those characterized by limited particle distribution.
Additional benefits include:
| Industry | Application | Examples of Use |
|---|---|---|
| Chemical and Polymers | Final product Amine, Benfield and other solid loops Carbon fiber production |
|
| Food and Beverage | Prefiltration Air, gas and vent filtration |
|
| Oil and Gas | Upstream Midstream |

2Fluids which do not swell, soften, or adversely affect any of the filter components.
3Recommended change-out differential pressure is 2.4 bard (35 psid), provided the maximum differential pressure (based on temperature) is not exceeded.
PERFORMANCE
Typical Flow Rates4 for Chemical and Polymer, and Oil and Gas Applications
Typical Flow vs. Differential Pressure for Application Sizing
Flow rate is for a 25.4 cm (10 in) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
Typical Flow Rates for Food and Beverage Applications
4Typical initial clean delta p per 254 mm (10 inch) cartridge, water at 20° C (68° F). For liquids with viscosity greater than 1cP, multiply the delta p by the viscosity.
