When a Pall PPC compressed air filter cartridge reaches the end of its service life, procurement teams often face a frustrating reality: long lead times, high OEM prices, and limited availability for legacy Pneumatic Products Corporation (PPC) series elements. Whether you are running PCC, PCS, MCC, MDC, MDS, or POC housings, there is a direct-fit alternative available from R+F FilterElements that meets or exceeds the original specification — at a fraction of the cost and with European stock availability.
This guide maps the most common Pall PPC cartridge codes to their R+F equivalents, explains the suffix system (SU, AF, HT), and helps you select the correct replacement for your compressed air quality class.
Understanding the Pall PPC Series Codes
Pneumatic Products Corporation (PPC), now part of Pall Corporation, produced a wide range of compressed air filter housings under the PCC, PCS, MCC, MDC, MDS, and POC designations. Each housing accepts a specific cartridge diameter and length, and the suffix on the element code tells you the filtration function:
- SU — Standard coalescing or particulate element (general-purpose)
- AF — After-filter element (dry particulate, downstream of coalescer)
- HT — High-temperature variant (rated to 120 °C)
The numeric portion of the code (e.g. PCC-1001, MDC-2003) encodes the housing size and element position. When sourcing replacements, the critical parameters are the outer diameter, inner diameter, and length — not the OEM part number itself.
Why Switch to R+F FilterElements?
R+F FilterElements offers its own range of compressed air filter elements — the RF-C coalescing and RF-P particulate series — manufactured to ISO 8573-1 performance standards. These elements use borosilicate glass microfibre media with a downstream drainage layer, achieving 99.99% efficiency at ≥ 0.1 µm for liquid aerosols (RF-C) and ≥ 0.3 µm for solid particulate (RF-P).
Because R+F elements are dimensionally interchangeable with the original PPC cartridges, no housing modification is required. The existing bowl, head, and drain remain in service — only the element is replaced.

How to Identify Your Pall PPC Element
If the element label is still legible, the part number format is typically: [Series]-[Size Code][Suffix], for example MDC-2003SU. The series prefix (PCC, MCC, MDC, MDS, POC) identifies the housing family; the numeric code identifies the element size; the suffix identifies the grade.
If the label is missing, measure the element:
- Outer diameter — measure across the widest point of the filter media
- Inner diameter — measure the bore (centre tube)
- Length — measure from end cap to end cap
Bring these three dimensions to the R+F cross-reference tool or contact our engineering team directly via the enquiry form. We stock the full RF-C and RF-P range from European warehouses, with typical despatch within 24–48 hours.
Selecting the Correct Grade for Your Application
Compressed air filtration is typically staged: a coalescing filter (SU-grade) removes liquid oil aerosols and water droplets, followed by an after-filter (AF-grade) that captures any downstream particulate shed by the coalescer media. For applications requiring ISO 8573-1 Class 1 air quality — such as food contact, pharmaceutical packaging, or precision instrument supply — both stages are mandatory.
For applications where only bulk liquid removal is needed (e.g. general workshop air), a single coalescing stage using an RF-C element is often sufficient. Visit the compressed air filter range for full housing and element compatibility data, or use the Engineering Sizing Tool to confirm the correct element grade for your flow rate and inlet conditions.
