  • 11 FAQs for Industrial Vacuum | Blower Vacuum Best Practices

    What is vacuum? Vacuum is the term used to describe the region of pressure below atmospheric pressure or the surrounding area: 1 Atmosphere @ sea level = 14.7 PSIA = 0 PSIG = 29.92” Hg. How is vacuum measured? There are a number of units of measure that can be used to describe the level of vacuum. Vacuum can be expressed in either gauge or atmospheric values. What is the function of a vacuum pump? The main function of a vacuum pump is to: Handle air leakage and/or non-condensables into the vacuum system in order to maintain a specific vacuum level. How are vacuum pumps rated? Depending on the pump manufacturer, vacuum pumps are usually rated in ACFM or SCFM. ACFM or Actual Cubic Feet per Minute measures the volume of air at a given pressure under actual vacuum conditions (i.e. People also ask

    Low Vacuum – also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner. Medium Vacuum – is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer. It can be measured with a McLeod gauge, thermal gauge, or a capacitance

  • equipment - Confused Reading of Pressure on Vacuum Gauge

    Pressure gauges typically measure pressure relative to ambient, so "0" on a gauge means equal to ambient (~ 1 bar absolute pressure depending on where you are). In some cases, the units have a "g" at the end, for example "psig" to indicate that the measure is "gauge pressure" rather than absolute, but that isn't always the case.

    Another definition of the distinction between pressure and vacuum comes from the industries which use and make pressure and vacuum equipment. Broadly, if the force on the walls of the containing vessel is sufficient to permit its measurement directly, we are dealing with pressure technology but if the force is too small for direct measurement and has to be indirectly inferred, we are in the realm of vacuum technology.

  • Vacuum Basics and Applications | Abbess Instruments

    Vacuum ConceptsVacuum TerminologyVacuum EquipmentWhat is Pressure? Imagine a closed container with air, or some other gas, inside. Gases are composed of molecules that you can imagine as round elastic balls. Molecules move in straight lines until they collide with neighboring molecules or the container wall. Molecules of gas hitting the wall impose a force on the wall. The amount of this impact force per area of the container inner walls is called pressure. Since gases are considered fluids, the “pressure” exerted by these collisions applies to all surfaces of the container no matter what their orientation. At room temperature and normal atmospheric pressure, one cubic foot of air contains approximately 7×10^23 molecules moving in random directions and at speeds of around 1,000 miles per hour. The momentum exchange imparted to the walls is equal to a force of 14.7 pounds for every square inch of wall area. This atmospheric pressure can be expressed in a number of different units, but is commonly expressed in terms of the weight of...
