Instrument Air Packages


An Instrument Air Package consists of all the necessary equipment – air compressors, air receiver, air dryer and air filtration – to enable the supply of instrument quality air to a facility. Instrument quality air must be free of contaminants and water vapour, and should conform to the international ISO standard for compressed air quality. These standards are:

Maximum Number of Particles           0.1 – 0.5 micron/m3

Oil Vapour                                                   0.1 – 0.01 mg/m3

Water Pressure Dewpoint                   -40 – -60 degrees C

Components of the Typical Package:

  1. Air Compressors – Facilities are dependent upon instrument air to maintain their operation. Accordingly, most Instrument Air Packages include two compressors – one operating – the other a redundant standby.
  2. Air Receiver – An Air Receiver stores compressed air to provide additional capacity when required.
  3. Air Dryer – An Air Dryer removes water vapour from the compressed air to ensure that no water will condense from the air when used. The typical pressure dewpoint range is -40 to -100 degrees C.
  4. Air Filtration – Filters are required to remove oil vapour and particulates from the air stream.
  5. Heated Enclosure – The completed air compressor package is usually installed in a self-framed, heated enclosure.
