Overview

What it does

Tanks breathe as fuel is drawn and temperature changes. Every breath pulls in air, and with it, moisture and dust. The P566037 screws into your vent port and filters that air before it enters the tank. Less moisture means fewer water slugs at the bottom of your tank and cleaner fuel at the pump.

Key benefit

Who this suits

Workshops, farms, and small fleets running standard diesel or oil storage. If you have a 3/4" BSP vent port and you want basic protection without spending on high-end filtration, this does the job. It is not certified for aviation or pharma-grade applications, and it is not trying to be.

Frequently Asked Questions

Can't find your answer?

Contact Us
What is the Donaldson breather trap?

A threaded vent cap that filters air entering your tank, reducing moisture and dirt contamination in stored diesel or oil.

Will this fit my tank?

It has a 3/4" BSP male thread. Check your tank vent port is 3/4" BSP female. Most Australian diesel tanks use BSP fittings.

How often do I replace the element?

Inspect every service interval or when you notice restricted breathing. Dusty or humid sites may need more frequent replacement.

Is this top-spec filtration?

No. It is a value-tier breather that does basic moisture and dirt control. For high-spec or certified filtration, contact us for alternatives.

What warranty and support do I get?

12 months on defects. Filter element is a consumable. For technical advice or bulk orders, contact sales@goind.com.au or 07 3204 2240.
