Dew Point Basics
What Is Dew Point?
It is important to know about dew point in compressed air. Dew point is the temperature when water vapor turns into liquid. At this temperature, air cannot hold more water vapor.
Dew point shows when air is full of water vapor.
Water vapor changes into liquid at the dew point.
In compressed air systems, dew point is when water vapor becomes liquid as fast as it evaporates.
If you do not control dew point, water can build up in pipes and tools. This leads to rust and scaling. It can break equipment and make products worse. Different industries have dew point rules to keep air dry and safe. The ISO 8573-1 standard helps you know the right dew point for your job. Here is a table that shows dew point classes for different uses:
Quality Class | Dew Point (°C) | Application Areas |
|---|---|---|
1 | -70 | Electronics, pharmaceuticals |
2 | -40 | General industrial applications |
3 | -20 | Moderate sensitivity applications |
4 | 3 | Less sensitive applications |
5 | 7 | Basic industrial applications |
6 | 10 | Non-critical applications |

Dew Point vs. Humidity
You may wonder how dew point and humidity are not the same. Dew point is the temperature when moisture starts to turn into liquid. Humidity tells how close air is to being full of water vapor.
When air cools, it gets more full. Condensation happens at the dew point.
Relative humidity does not show all the moisture in the air.
This difference is important in compressed air systems. If you only check humidity, you may miss hidden moisture problems. Dew point tells you when water will form inside your system. Too much moisture can cause rust, broken equipment, and bad products. Many industries need strict dew point rules to stop downtime and keep products safe.
Compressed Air Moisture Issues
Effects on Equipment
Moisture in compressed air can hurt your equipment. Water makes rust and corrosion inside pipes and valves. Metal parts can wear out faster. Pneumatic tools may stick or stop if water removes lubricants. Water can freeze in cold weather and block air flow. Debris can build up in tubes and make airflow worse.
Moisture often comes from flooded water separators or clogged coolers. It can also come from using refrigerated dryers the wrong way. If you ignore these problems, repairs can cost a lot. You might have to stop work. Pulp and paper mills often get bad rust on cylinder pistons. This can break control valves and pressure systems. Seals can dry out and crack. Air leaks and performance gets worse.
Sollant knows these problems well. Sollant makes compressed air systems in China. Sollant uses strong parts and new technology to keep equipment safe. Sollant’s air-dryer-for-air-compressor helps take out moisture and protect your tools.
Tip: Check and test your system often to stop moisture problems and keep your equipment working well.
Impact on Product Quality
Moisture in compressed air can ruin products. Water in the system causes rust and scaling. This can hurt pipes and machines. Paint can look uneven or powder can clump together. In food and medicine, moisture helps bacteria and mold grow. This can spoil food and break tablets.
If you use compressed air for packaging, moisture can make food wet and unsafe. In electronics, water can cause oxidation and bad solder joints. Rust and water can make control instruments give wrong readings. You might not meet air purity rules.

Check and fix your system often to save energy. Sollant makes compressed air systems that save energy. Sollant’s air-dryer-for-air-compressor takes out moisture and lowers your costs. Sollant’s products help your business run better.
Tip: Keeping your compressed air system dry uses less energy and saves money.
Pressure and Dew Point
Pressure Dew Point Explained
When you use compressed air in your factory, you need to know about pressure dew point. This is the temperature at which water vapor in the air will start to condense into liquid at the system’s working pressure. As you increase the pressure in your system, the dew point also rises. This means water can form inside your pipes and tools even if the air feels dry outside.
The pressure dew point tells you how much moisture remains in your compressed air at full line pressure.
If the dew point is too high, water can condense, causing rust, equipment failures, and product defects.
Keeping a low dew point helps your system run smoothly and protects your products.
For example, if you have air with a dew point of -10 °C at normal pressure, compressing it to 2 atm raises the dew point to about -1 °C. This shows that compressed air holds less moisture at higher pressures, so you must control the dew point to avoid problems.
Sollant, a leading air compressor factory in China, builds reliable machines and air dryers that help you keep the dew point low. Their products are high quality and affordable, making them a smart choice for your business.
Atmospheric vs. Pressure Dew Point
You might hear about both atmospheric dew point and pressure dew point. These terms are not the same. The table below shows the difference:
Type of Dew Point | Definition |
|---|---|
The dew point of the compressed air at full line pressure, which increases with compression. | |
Atmospheric Dew Point | The dew point if the air is fully depressurized to atmospheric conditions, which is lower. |
When you compress air, the dew point goes up.
When you release the pressure, the dew point drops.
For example, compressed air at 200 PSIG may have a pressure dew point of -40º F, but this changes as you lower the pressure.
You need to convert between these two dew points for accurate system design. Many charts use different pressure units or only show certain values, making conversion tricky. Using the right calculation method helps you avoid mistakes and keeps your compressed air system safe and efficient.
Tip: Always measure and control the dew point at the pressure your system uses. This helps you prevent corrosion, save energy, and meet industry standards.
Dew Point Measurement and Control
How to Measure Dew Point
You need to check dew point to keep your compressed air safe. Dew point measurement shows how much water is in your air. If you do not check, water can build up and cause harm.
There are two main ways to measure dew point in compressed air. Each way has good and bad points:
Measurement Method | Accuracy | Advantages | Disadvantages |
|---|---|---|---|
Chilled Mirror Hygrometers | Very accurate, works in many conditions, does not drift | Expensive, needs care, slower to react | |
Polymer Capacitive Dew Point Sensors | ±1–2 °C (general use) | Cheaper, good for many jobs, small and easy to use | Not as accurate, may not work for very dry air |
You should check dew point readings often. Here are some best tips:
Follow the calibration plan from your sensor’s maker. Most sensors need recalibration every one or two years. In tough places, check more often.
Use a trusted tool or service to compare your sensor’s readings.
Do regular checks with a portable hygrometer to make sure your readings are right.
New technology makes dew point checks easier and better. Some new sensors use smart programs and machine learning. These can help you save energy and find problems early. Portable tools like the Easidew PDP Dryer Portable let you record data and check dew point in many places. Many new systems use IoT sensors for real-time checks. This helps you keep your compressed air system working well.
Tip: Regular dew point testing helps you find moisture problems before they cause damage or stop your work.
