Venturi Tube - an overview ScienceDirect Topics

Venturi tubes, which are constrictions or “throats” in fluid conduits, are regions of reduced pressure that are used in a number of devices. A perfume atomizer, for example, operates by having air forced from a squeeze-bulb through a Venturi throat that reduces the pressure above an open tube dipped into liquid perfume.

Venturi Air Movers Down Under Mining

Venturi Air Movers operate on the venturi principle where small volumes of high velocity air, from your compressed air line move through the air mover’s nozzles creating a pulling action which entrains a larger volume of air that exists out the diffuser. Up to 30 times the amount of compressed air supplied can be moved by this equipment.

Venturi Sprays Code 1912

2015-6-9  The Conflow Code 1912 - Venturi Spray produces a powerful jet providing a dense coverage of dust suppression water. As the spray fills the body tube with water, it creates a vacuum into which the surrounding air and dust is drawn. This has a dual effect of capturing and suppressing airborne dust and diluting any gasses that may be in the vicinity.
