At the heart of the Flo Control can is a button to regulate how fast the fluid is released. This is part of a mechanism which allows air to enter the container to enable the liquid to flow freely. The result is that fuel is dispensed much quicker than with conventional rivals, but a strict control is still maintained. The button can also be used to slow the flow right down, meaning smaller tanks can be filled without the risk of spills.
As no petrol can be released unless the button is pressed, there’s no danger of losing fuel if it’s knocked over. Flo Control also has a spout dust cap to keep contamination to a minimum, and the cans come colour-coded for unleaded, diesel and two stroke.
