Why is humidity one of compressed air's main "enemies"?

Condensate and air contamination have a negative influence on the reliable operation of air distribution networks and equipment requiring compressed air.

Network problems :

Corrosion
Pressure loss
Contamination of end products
Icing
Curative maintenance

Consequences for production equipment :

Clogging
Excessive wear
Outages
Production delays

How to choose the right compressed air dryer?

Step 1: Know the compressed air quality level required for your sector.

By consulting ISO 8573-1 STANDARD :

The international quality standard for compressed air, offers a simple classification system for the three main contaminants present in any compressed air system: IMPURITIES, WATER and OIL.

Class	Solid particles			Dew point	Oil content in mg/m3
	Maximum number of particles per m3
	0.1 to 05 μm	0.5 to 1 μm	1 to 0.5 μm
1	100	1	0	-70°C	0,01
2	100 000	1 000	10	- 40°C	0,1
3	-	10 000	500	-20°C	1
4	-	-	1 000	+3°C	5
5	-	-	20 000	+7°C	-
6	-	-	-	+10°C	-

AIR QUALITY TO ISO 8573.1 - CLASS 1.4.1

Refrigerated dryers

Compressed air for frost-free industrial applications.

Dew point +3°C

AIR QUALITY TO ISO 8573,1 - CLASS 1,2,1

Modular adsorption dryers

Compressed air for demanding industrial applications or those exposed to frost.

Dew point -40°C

STEP 2: Establish pressure dew point.

It corresponds to the temperature at which water vapor condenses and turns into water at air pressure.

A dryer is required to remove this moisture.

Once you know the required air purity and pressure dew point, you've determined the best drying method.
