By using the mechanical built in hand pump a vacuum is created in the fully sealed 9.5 litre oil resistant container. This vacuum can then be accessed via a comprehensive range of hoses and fittings (included) to extract various fluids. This unit can also be used to vacuum bleed brake systems in automotive applications.
An extremely useful piece of equipment for the mobile professional automotive technician or serious home mechanic as it is self contained and requires no shop air to operate.
