Condensate management

Condensate management is one of the most important factors when using compressed air. It heavily influences your compressor’s performance and lifespan. But what exactly is the problem with condensate? And what solutions are there? That’s what you’ll find out here.

Air compressor condensate management is an essential part of maintaining a reliable and high-performing compressed air system. As air is compressed and purified, condensate—made up of water, oil, and other contaminants—naturally forms and must be collected. Without proper removal, this moisture can accumulate and cause damage to internal piping or compromise air quality.

This is especially critical in industries such as pharmaceuticals, food processing, and automotive manufacturing, where even small traces of moisture or oil can lead to product contamination or oxidation. To prevent such risks, systems rely on dedicated tools such as an air compressor condensate drain to remove collected liquid efficiently and an air compressor condensate filter to separate oil and other pollutants before disposal.

A compressed air condensate drain is typically part of a broader condensate management system, which is designed to safely handle and discharge condensate without disrupting operations. These systems come in various types, offering different levels of automation and filtration to suit specific applications. Regular monitoring and disposal are key to keeping moisture away from the compressor’s internal components and maintaining clean, dry, and safe compressed air.


Mark Water Separator

Oil-water separators - as the name implies - separate the water in the air from the oil used to lubricate your compressor. During compression, the two get mixed together and heated in order to properly clean the air.

When the compressor starts cooling after compression, the water and other impurities cleaned from the air cool down and form condensation. If these particulates were to be left in, they would disrupt your compressor’s inner workings and damage it.

How an oil-water separator works:

 

  1. Condensation enters the separator.
  2. The first stage of separation is handled by depressurising the condensate, after which it runs through a filter that lets water pass through.
  3. The filter gradually starts to sink under the weight of the oil as more and more condensate passes through. The oil filter is changed just before it submerges.
  4. The water that passed through is cleaned of possible remaining oil with activated carbon.
  5. Clean water is disposed of through the separator’s outlet.


Cyclonic separators internally create a vortex of air - like a tornado - to clean the air. As it swirls, impurities like dust particles and water droplets are expelled from the air and collected in a dedicated container.

This type of separator catches about 99% of the air’s impurities.


Drain valves are the part of your condensate management system that allows you to safely dispose of condensate to maintain a high level of efficiency. Although the drain valve isn’t a separator in and of its own, it is a crucial part of any system.


Air dryers

Another option to eradicate moisture particles or contaminants are air dryers. There are four different types:

  1. Chemical compressed air dryers
  2. Refrigerating compressed air dryers
  3. Desiccant compressed air dryers
  4. Membrane compressed air dryers
