DEF / AdBlue Tank & Pump Filter is used for filtering diesel exhaust fluid (DEF / AdBlue) in SCR systems so urea crystals and debris do not block the pump and dosing injector. ISO 22241 is the reference cited for it on drawings, datasheets and purchase orders.
What ISO 22241 Means for DEF / AdBlue Tank & Pump Filter
The dimensions in the table below are supplied to suit ISO 22241. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
DEF / AdBlue Tank & Pump Filter Dimensions
| Size | Outer diameter (mm) | Length (mm) | Micron rating (u00b5m) | Media |
|---|---|---|---|---|

Specifying DEF / AdBlue Tank & Pump Filter Beyond the Standard
- Material: Only SS316L or plastics compatible with ISO 22241; ordinary steels contaminate DEF.
- Rating: 10–40 µm depending on position.
- Freeze tolerance: Must survive repeated freezing of DEF.
When DEF / AdBlue Tank & Pump Filter Is Not the Right Choice
