A 40 micron pleated filter cartridge is a listed glass fiber grade for coarse suspended-particle prefiltration. The exact 40 µm rating is not established by the detailed PP standard list, so PP availability must be confirmed separately.
For a coarse stage that needs a finer stated target than 50 µm, evaluate the glass fiber configuration against its measured efficiency. Check the compatibility of the media, supporting layers, cage and seals; selecting glass fiber is not equivalent to selecting only a pore size.
For a process with intermittent high solids, compare cartridge replacement effort with an appropriate upstream separation stage. A listed 40 µm rating does not establish an unlimited dirt capacity or a fixed interval between changes.
This is a cross-material selection guide. The linked family pages are the catalog references, not substitutes for a confirmed grade-specific data sheet. Listed family information does not establish that every combination of dimensions, seals and rating is available.
| Material / request | Catalog status | Selection question |
|---|---|---|
| Glass Fiber | Exact 40 µm grade listed on the detailed family page | Confirm the multilayer media, support construction and approved operating conditions. |
40 µm states the finer target. Both grades are listed in the glass fiber family, while 50 µm is also listed for PP. Compare the same construction and test method when assessing whether a finer grade is useful.
Nearby selection guides: 30 µm · 50 µm. Compare equivalent efficiency definitions and cartridge dimensions before changing grade.
| Required rating | 40 µm; state nominal/absolute definition and required retention efficiency. |
|---|---|
| Availability | Listed material families above; confirm the exact orderable combination. |
| Dimensions and interface | Confirm actual length, OD, ID, end-cap drawing and gasket arrangement against the existing housing. |
| Fluid and hydraulics | Provide fluid composition, concentration, viscosity at temperature, flow and allowable clean differential pressure. |
| Operating limits | Obtain configuration-specific temperature, pressure and change-out limits. Limits cannot be inferred from the micron number. |
| Documents | Request a grade-specific data sheet, retention method and any product-contact or validation records required for the application. |
Request the 40 µm glass fiber retention data, construction drawing and operating envelope. Trial the element under the expected solids peaks and record the quality endpoint as well as pressure-drop growth.
No grade-specific flow rate, retention percentage, service life, certification or microbial-validation result is asserted by this guide. Those values must come from documentation for the ordered configuration.

The number alone does not say. Request the retention efficiency, challenge conditions and test method for the exact grade. Do not assume a universal efficiency percentage from the word nominal or absolute.
Match the actual overall length, outside and inside diameters, end-cap interface and seal arrangement against the housing drawing. A matching micron rating or nominal length does not establish fit.
No. Particle-rating information alone does not establish sterilizing performance or removal of dissolved salts and chemicals. Microbial claims need product-specific evidence and process validation; dissolved contaminants require an appropriate treatment process.
Send the required rating and efficiency, liquid and concentration, flow, viscosity, temperature, pressure, particle load, cartridge dimensions, end-cap drawing, seals, quantity and required documentation. Ask INCE filtration to confirm the exact configuration before purchase.
