This is how we measure how dry the air is. It is NOT an indication of the air temperature. Dew Point is the temperature at which moisture becomes apparent.
MOISTURE IS DAMAGING.
Moisture in compressed air used in a manufacturing plant causes problems in the operation of pneumatic air systems, solenoid valves and air motors. This moisture causes rust and increased wear of moving parts as it washes away lubrication. Moisture adversely affects the colour, adherence, and finish of paint applied by compressed air. Moisture jeopardizes process industries where many operations are dependent upon the proper functioning of pneumatic controls. The malfunctioning
of these controls due to rust, scale, and clogged orifices can result in damage to product or in costly shutdowns. Additionally, the freezing of moisture in control lines in cold weather commonly causes faulty operation of controls. Corrosion of air or gas operated instruments from moisture can give false readings, interrupting or
shutting down plant processes.
SELECTING THE RIGHT DRYER
Before looking at the several types of dryers available, we need to look at what to consider in deciding which dryer is best for the specific requirements.
KNOW THE SPECIFIC USES OF THE COMPRESSED AIR
The selection of an air dryer is done best by the professional (& we are here to help if required) who knows or learns the particular end uses, the amount of moisture which each use can tolerate and the amount of moisture which needs to be removed to achieve this level. Air which may be considered dry for one application, may not be dry enough for another. Dryness is relative. Even the desert has moisture. There is always some moisture present in a compressed air system regardless of the degree of drying. Different types of dryers, therefore, are available with varying degrees of pressure dew point ability. To specify a dew point lower than required for an application is not good engineering practice. (Naming a pressure dew point is how to state the degree of dryness wanted.) It may result in more costly equipment and greater operating expense.
We can Supply the right Dryer for your application & budget do we need
- Inbuilt FF (Full Feature) Our compressors come with the option of an integrated dryer. The advantages of this is the air that leave the compressor is already dry. Footprint is reduced and so is power supply and monitoring.

WHY Does COMPRESSED AIR CONTAIN MOISTURE? WHAT DOES DEW POINT MEAN EXACTLY?
MOISTURE IS ALWAYS PRESENT. It is all around us in the air we breath.
All atmospheric air contains some water vapour which will begin to condense into liquid water in the compressed air or gas system when the air or gas cools past the saturation point, i.e., the point where it can hold no more water vapour.
The temperature at which this happens is known as the dew point. This dew point becomes all-important in determining how much drying is needed.
Or putting it simply the air we compress contains moisture. Moisture does not compress like air, in fact compresses very little. When we take a volume of air say 100 Litres and reduce it to 10 Litres it has the same amount of water.
The water will now condense and become apparent and we see this as droplets in compressed air.
