How big is a micron ?

  • Atmospheric dust < 5 microns
  • One inch contains 25,400 microns
  • Tobacco smoke < 0.5 microns
  • Human hair > 5 microns
  • One millionth of a meter.
  • A micron is very, very, small !

Did you know ?

  • A 3mm hole will pass 11 L/S of air at 7 bar - this is equal to 3.5 kW.
  • One 300 m/h compressor can generate up to 29 liters of water per day.

What is a Dew point ?

In simple terms, a dew point describes how much water vapor is present and tells us how cold the compressed air can get before liquid water will form. To prevent water in your air system, choose a dryer that produces a dew point temperature below the lowest possible temperature that downstream air lines and equipment will be exposed to.
