Abstract
A device for producing vacuum using the Venturi effect, systems utilizing the device, and methods of making the device are disclosed. The device has a housing defining a Venturi gap, a motive passageway converging toward the Venturi gap and in fluid communication therewith, a discharge passageway diverging away from the Venturi gap and in fluid communication therewith, and a suction passageway in fluid communication with the Venturi gap. The suction passageway has an interior surface with a surface topography that renders the interior surface hydrophobic and has an oleophobic coating applied to the interior surface while maintaining the surface topography.
