A Donaldson filter rarely gets chosen on its own â it's specified to match a specific piece of equipment (an engine, a compressor, a hydraulic system) that a maintenance team is already committed to keeping running, which is why cross-referencing against an existing part number matters more with this brand than almost any other we stock. Z & F Corporation Ltd supplies 284 genuine Donaldson lines.
What You'll Find
- Fuel filters & water separators â spin-on and cartridge types for diesel engines and fuel systems.
- Air filters â primary and safety filters, including radial-seal designs for engine intake protection.
- Hydraulic & breather filters â for hydraulic circuits and tank breather protection.
- Fitting accessories â hose clamps and elbow fittings that complete a filtration installation.
Physical dimensions â outer diameter, inner diameter, and length â identify most of these filters as reliably as a part number, since the same physical filter is often sold under several part numbers depending on the equipment manufacturer's own catalogue. See our Filtration category for how these cross-reference against other aftermarket filter brands.
Matching by Dimension, Not Just Part Number
If you have the old filter but not a legible part number, outer diameter, inner diameter (for cartridge types), and length are usually enough for us to confirm the correct Donaldson filter or a genuine equivalent.
We are not Donaldson, and not an authorised Donaldson distributor â genuine stock only, sourced and supplied independently, with any brand-specific disclosure noted on the relevant product page. Orders ship worldwide with export documentation as standard; fleet operators and industrial maintenance teams across Africa, South Asia, and the Middle East are regular customers for this range alongside the UK.
Frequently Asked Questions
Can you match a Donaldson filter by dimensions alone?
Usually yes â outer diameter, inner diameter, and length are normally enough to confirm the correct filter or a genuine equivalent, even without a legible part number.
Do Donaldson filters cross-reference against other aftermarket brands?
Many do â see our Filtration category for cross-referencing against AC Delco, Fleetguard, Fram and similar brands.
Do you supply fuel, air and hydraulic filters together on one order?
Yes â a mixed filtration order against a service schedule or shutdown list is one of the most common ways we receive orders for this brand.
