A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
Automated pool cleaners use pressure-side water flow to collect sediment and debris; Clarinets use a reverse taper to speed the air down the tube, enabling better tone, response and intonation [5] The leadpipe of a trombone, affecting the timbre; Industrial vacuum cleaners use compressed air; Venturi scrubbers are used to clean flue gas emissions
The ejector venturi is unique among available scrubbing systems since it can move the process gas without the aid of a fan or blower. The liquid spray coming from the nozzle creates a partial vacuum in the side duct of the scrubber. The partial vacuum is due to the Bernoulli effect, and is similar to water aspirators used in chemistry labs ...
A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.
A vacuum cleaner, also known simply as a vacuum, is a device that uses suction, and often agitation, in order to remove dirt and other debris from carpets, hard floors, and other surfaces. The dirt is collected into a dust bag or a plastic bin.
For air with a heat capacity ratio =, then =; other gases have in the range 1.09 (e.g. butane) to 1.67 (monatomic gases), so the critical pressure ratio varies in the range < / <, which means that, depending on the gas, choked flow usually occurs when the downstream static pressure drops to below 0.487 to 0.587 times the absolute pressure in ...
Once a lead is generated, salespeople will attempt to contact this lead to schedule an appointment to show the Rainbow Cleaning System (sometimes called a vacuum, sometimes called an air filter). Rexair has been issued a certificate from the Association of Home Appliance Manufacturers (AHAM), [officially adding to] the title of vacuum cleaner ...
Smaller dust collection systems use a single-stage vacuum unit to create suction and perform air filtration, where the waste material is drawn into an impeller and deposited into a container such as a bag, barrel, or canister. Air is recirculated into the shop after passing through a filter to trap smaller particulate. [citation needed]
