Condensate Drains: Everything You Need to Know

Description: Air Compressor Condensate DrainsCompressed air is used in a wide range of applications and because of this has become a staple of industry.  Compressed air does have its drawbacks, however.  Compressed air cannot hold as much moisture which means that condensate develops.  Other impurities can also find their way into the system, such as oil and dirt, and these often mix and become acidic which causes damage to the machinery.  Condensate drains help to alleviate the problem.  These drains are attached to compressed air systems and are designed to remove condensate.

Condensate Drain Options


There are a few options when it comes to condensate drains and they all have different points to consider.

  • Non-Sensor Condensate Drains
  • Manual Condensate Drain Valve – this valve remains slightly open at all times and can accrue more of a cost because of the lost air and it also requires constant attention to operate.
  • Solenoid or Timed Valve – these valves are also prone to wasting money and will open and close at regular intervals regardless of the presence of condensate. 
  • Sensor Condensate Drains
  • Float Type Sensor – these types seal when not draining condensate.  However, they are also prone to malfunction and will struggle when presented with oily or sticky condensate. 
  • Zero Air Loss Condensate Drain – this is the most efficient option for condensate removal.  These have a sensor which will measure the amount of condensate and will open when it reaches a particular level.  These drains require electricity and will open and close fast enough to avoid the loss of air.
