STOP FUEL SPLASH WITHOUT CHOKING THE TANK
Donaldson breather filter with anti-splash trap. DN25 (1 inch BSP male). Vents tank pressure while keeping fuel inside during transport.
What it does
Your diesel tank needs to breathe when temperature and fill level change. This Donaldson breather vents air in and out but traps liquid fuel so you don't lose product over corrugations or speed humps. DN25 male thread screws into a standard tank bung. 100 grams, simple to fit.
Who it suits
Ute-mounted poly tanks, fuel trailers, workshop bulk storage. Anywhere you have a mobile tank that rocks around and vents through a cap. Donaldson is the filtration brand mining and ag fleets already run, so parts backup is sorted.

Frequently Asked Questions
Can't find your answer?
Contact UsWhat is the Donaldson breather filter?
A vent filter that lets your tank equalise pressure while catching fuel splash. Stops liquid carry-over during transport.
Why do I need an anti-splash trap?
Without one, fuel can vent out the breather when the tank rocks on rough roads. The trap catches liquid so only air passes through.
What size fitting does it use?
1 inch BSP male thread. Common size for tank cap bungs on portable diesel units.
Is this suitable for petrol tanks?
Check with Donaldson compatibility. Designed primarily for diesel fuel systems. For petrol queries contact sales@goind.com.au or 07 3204 2240.
What warranty and support is available?
12-month manufacturer warranty on defects. Filter element is a consumable. For technical support contact sales@goind.com.au or 07 3204 2240.
