Coalescing Filter Element Cross Reference: Donaldson, Hankison, Deltech, Finite, Parker, Champion & Walker
The coalescing filter in your compressed air line is the part that catches oil aerosols and fine water droplets before they reach your tools, paint guns, and dryers. When the element loads up, you need the replacement fast, and the hard part usually isn’t the filter. It’s the coalescing filter element cross reference: the number on your housing is a Donaldson, Hankison, Parker, or Finite number, and you want an equivalent that fits the same housing.
This guide covers how line filter element numbers are written by the major brands, where to find yours, and how to order the matching KELTEC OEM equivalent coalescing element from Compressor Filter Hub.
Why Coalescing Element Numbers Are Confusing
Compressor makers sell their own line filters, and so do the filtration brands: Donaldson/Ultrafilter, Hankison, Deltech, Finite, Parker, Champion, Walker, and others. Each one uses its own numbering style, and each one rates its elements on its own scale.
- Every brand formats differently. Slashes, dots, dashes, leading zeros, and letter codes all show up.
- Grade numbers aren’t universal. A “Grade 10” or “Grade 12” on a Hankison or Deltech element belongs to that brand’s own grade system. Don’t assume the same grade number means the same thing on another brand.
- The housing decides the fit. The element has to match the housing it goes into, so the safest match is the exact element part number, not the grade or the size.
That’s why we list the OEM element number and the KELTEC number side by side on every product page. Start with the number, and the rest follows.
How Brands Write Their Element Numbers
The same element can be written several ways on labels, invoices, and purchase orders. Here’s what to expect:
| Format | Example | What to watch for |
|---|---|---|
| Slash | SMF05/20 (Donaldson/Ultrafilter) | The slash is often dropped when typed: SMF0520 |
| Dotted | 07.4442-01 (Hankison) | Keep the leading zero; the dot and dash are formatting |
| Dashed | AU15-060 (Finite) | Also shows up as AU15060 on POs |
| Plain digits | 5005471 (Deltech) | Copy every digit; similar numbers are different elements |
| Letters and digits | P3NKA00ESE (Parker), E30850X1 (Walker), C60EE (Champion) | Zero vs. letter O, and every letter counts |
Where to Find Your Element Number
- The old element. Most coalescing elements have the number printed on the end cap or the media wrap. Take a photo before you toss it.
- The housing label. Many filter housings carry a tag listing the housing model and the replacement element number.
- Your last invoice or parts list. Check how it was written; the slash, dot, or dash may have been dropped.
- The housing model alone. If the element is unreadable, send us the housing brand and model plus photos and we’ll help you track down the number.

Tips for Searching a Coalescing Element Number
- Search the number exactly as printed first, including slashes, dots, and dashes.
- If nothing comes up, try it with the punctuation removed (SMF05/20 → SMF0520, AU15-060 → AU15060).
- Keep leading zeros. Hankison 07.4442-01 starts with a zero for a reason.
- Check zeros against the letter O and ones against the letter I on letter-and-digit numbers like P3NKA00ESE.
- Still stuck? Email us the number and a photo of the element or housing label. Matching from a photo beats guessing formats.
Coalescer or Separator? Know Which Part You Need
A coalescing line filter sits downstream of the compressor and cleans the air going to your tools. The air/oil separator sits inside an oil-flooded rotary screw compressor and keeps the compressor’s own oil in the machine. Both can be the cause when you see oil in your air, so check both. Our post on how to tell if oil in your air lines is the separator walks through the difference.

Frequently Asked Questions
Is SMF05/20 the same as SMF0520?
Yes. The slash is formatting. SMF05/20, SMF0520, and SMF 05/20 identify the same Donaldson/Ultrafilter element.
Can I match a coalescing element by grade alone?
No. Grades are brand-specific, and the element also has to fit your housing. Order by the element part number, or send us the housing details and we’ll match it.
What is a KELTEC OEM equivalent?
KELTEC Technolab builds replacement elements to match the fit, form, and function of the original part. Every product page lists the OEM number it replaces and the matching KELTEC number. For more, read OEM vs OEM equivalent filters.
I only know my filter housing model. Can you help?
Yes. Send us the housing brand, model, and photos of the housing label and old element, and we’ll find the right replacement.
