Choosing a 3 Micron PP Pleated Filter Cartridge
Use 3 micron where the documented 5 micron performance is insufficient and the process does not require the selected 1 micron grade. Confirm the complete operating envelope.
A micron rating describes a filtration grade, not a guaranteed percentage removal. Confirm whether the selected cartridge is nominally or absolutely rated, the test method and retention efficiency at the required particle size.
Pleated media provides filtration area within the cartridge envelope. The PP media and support structure must be specified together with the retention grade. Actual performance depends on media construction, liquid viscosity, flow, particle distribution and cartridge loading. This cartridge is intended for suspended particles; it is not a desalination or dissolved-contaminant treatment stage.
3 Micron Cartridge Specifications
Listed construction options are based on the INCE PP pleated cartridge series specifications. Confirm availability of the complete combination before ordering.
| Item | Specification / selection requirement |
|---|---|
| Filtration rating | 3 µm; efficiency and test method to be confirmed |
| Filter media / structure | PP polypropylene media, non-woven support and PP outer cage |
| Nominal lengths | 10, 20, 30, 40, 50, 60 and 70 inch; confirm actual sealing length |
| Diameter options | 60 / 64 / 68 / 84 / 131 mm OD (approximately ±1 mm); 28 mm ID; confirm the selected dimensions |
| Core / end caps | PP or 316L stainless steel center core; PP end caps with optional stainless steel insert |
| Seals | Silicone, EPDM, NBR or FKM options; compatibility review required |
| Assembly | Hot-melt-welded connections without adhesive |
| Series temperature limit | Normal operation ≤55°C; maximum listed condition 80°C at ΔP ≤0.10 MPa (1.0 bar). Confirm the exact configuration. |
| Series differential-pressure limit | At 25°C, ΔP ≤0.42 MPa (4.2 bar); this is not a housing pressure rating or a change-out recommendation |
| Change-out differential pressure | Request a confirmed limit for the ordered cartridge. Do not exceed the applicable cartridge or housing limit. |
| Flow rate | Request the 3 µm pressure-drop curve for the selected length and diameter |
Temperature and pressure limits are not a guarantee of simultaneous operation at both maxima. Sanitization or steam use requires a separately approved configuration and operating procedure; a stainless steel insert alone does not establish steam compatibility.
3 vs 5 micron: Selection Comparison
Select using the downstream particle specification and verified retention curves. The micron numbers do not establish a proportional change in service life or flow.

Dimensions, End Caps and Sealing
Match the housing
Provide a dimensional drawing or an existing cartridge sample. Check actual length, OD, ID, support and sealing faces rather than relying only on the nominal inch size.
Select the interface
The series lists flat, 215, 222, high 222, 226 and threaded connections, with tip and cover options. Confirm the adapter and opposite-end arrangement as a complete assembly.
Review chemical compatibility
Specify the liquid, concentration and temperature. PP media, center core and gasket compatibility must all be checked for the proposed process.
Applications to Evaluate
Water treatment
Evaluate suspended-solids removal and staged prefiltration using feed-water analysis. RO pretreatment requires the membrane supplier’s specified particle-removal performance.
Process liquids
Consider compatible chemical and industrial liquid clarification. Select the rating against the actual downstream requirement and verify flow at process viscosity.
Documented production processes
Food, beverage and other controlled processes require application-specific material declarations and qualification. Request the documents for the exact supplied configuration.
Frequently Asked Questions
What does a 3 micron PP pleated filter cartridge mean?
A 3 micron PP pleated filter cartridge provides an intermediate filtration grade between 1 and 5 micron for compatible water and industrial process liquids. The stated micron rating must be paired with a retention efficiency and test method; it is not automatically an absolute rating.
3 vs 5 micron: which should I choose?
Select using the downstream particle specification and verified retention curves. The micron numbers do not establish a proportional change in service life or flow.
Which cartridge lengths and diameters are available?
The series lists 10, 20, 30, 40, 50, 60 and 70 inch nominal lengths, 60, 64, 68, 84 or 131 mm outside diameters and 28 mm inside diameter. Confirm the exact combination and dimensional drawing for the selected rating.
Can I use this PP cartridge in my existing housing?
Confirm actual length, OD, ID, end interfaces, sealing arrangement and gasket material against the housing drawing. A matching micron rating or nominal length alone does not establish compatibility.
Is this cartridge suitable for RO, food or pharmaceutical filtration?
Suitability depends on liquid compatibility, required retention, operating conditions and application-specific documentation. Ask for relevant material declarations and validation; the cartridge is not presented as a sterilizing-grade filter.
When should the cartridge be replaced?
Use an approved change-out differential pressure below the applicable cartridge and housing limits, or replace earlier if process quality or flow requires it. Obtain a confirmed threshold for the ordered configuration.
What information is needed for a quotation?
Send the micron rating, dimensions, end-cap drawing or sample, core and gasket requirements, liquid, flow rate, temperature, operating pressure, solids loading, quantity and required documentation.
