  2. Gas duster - Wikipedia

    en.wikipedia.org/wiki/Gas_duster

    A dust spray can often be used as a freeze spray. Many gas dusters contain HFC-134a (tetrafluoroethane), which is widely used as a propellant and refrigerant. HFC-134a sold for those purposes is often sold at a higher price, which has led to the practice of using gas dusters as a less expensive source of HFCs for those purposes.

    en.wikipedia.org/wiki/Vacuum_pump

    The Roots blower is one example of a vacuum pump. A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [1]

    Vacuum systems usually consist of gauges, vapor jet and pumps, vapor traps and valves along with other extensional piping. A vessel that is operating under vacuum system may be any of these types such as processing tank, steam simulator, particle accelerator, or any other type of space that has an enclosed chamber to maintain the system in less than atmospheric gas pressure.

  5. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    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.

  6. Dust collector - Wikipedia

    en.wikipedia.org/wiki/Dust_collector

    A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.

  8. Central vacuum cleaner - Wikipedia

    en.wikipedia.org/wiki/Central_vacuum_cleaner

    Air and dust are sucked at high speed into the collection vessel at a direction tangential to the vessel wall, creating a fast-spinning vortex. Roughly speaking, the dust particles and other debris spiral outward to the wall of the vessel by centrifugal force , where they fall due to gravity into the bottom of the collection bin.
