CLEAN VENTING WITHOUT THE FUEL SPLASH MESS
Donaldson breather trap for vented fuel tanks. 3/4 inch BSP male thread. Stops splash-back, keeps debris out during fill and draw cycles.
What it does
Vented fuel tanks breathe in air as you draw fuel out and push air out as you fill. Without a breather trap, you get fuel spitting out the vent during fills and dust sucked in during draws. This Donaldson fitting screws into the vent line and solves both problems: it traps splash-back on the way out and filters incoming air on the way in. Light aluminium body, 3/4 inch BSP male thread to suit common tank vent caps.
Who it suits
Fleet workshops, farm fuel setups, mobile service rigs, anywhere you have vented diesel or petrol storage. If you are tired of fuel stains around the tank vent or worried about dust getting into the tank, this is the fix. It is a value-tier unit: Donaldson filtration quality without the cost of a premium breather assembly. Does the job, fits the budget.
