What is “the gas supply is not less than 0. 2m\u00b3 @ 0.3MPa \/min \u201d?<\/h2>\n

This parameter is the key performance index of compressed air system or pneumatic equipment, indicating that the pressure is0.3 MPa (MPa)<\/strong>stable output air volume per unit timeno less than 0.2 cubic meters (m\u00b3)<\/strong>, the time unit isper minute (min)<\/strong>.<\/p>\n

Standard writing forms description<\/h2>\n

it is recommended to adopt internationally accepted and unambiguous engineering expressions:<\/p>\n

    \n
  • numerical unit working condition<\/strong>, use the @ symbol to connect pressure conditions (industry practice, non-mathematical multiplication sign);<\/li>\n
  • unified use of pressure unitsMPa<\/strong>(Instead of kgf\/cm² or bar), avoid conversion errors;<\/li>\n
  • for unit volumem\u00b3<\/strong>, Time Unitmin<\/strong>, slash “\/” cannot be omitted;<\/li>\n
  • “Not less than” should be explicitly written\u22650.2 m\u00b3\/min @ 0.3 MPa<\/strong>(More in line with technical documentation specifications).<\/li>\n<\/ul>\n
