If you are wondering about the best air dryer for plasma cutters, this write-up is for you.
Plasma cutting is a popular metalworking technique that requires high temperatures to melt and cut through metal. However, the high temperatures used in plasma cutting also produce a significant amount of moisture that can damage the equipment and create safety hazards. To prevent this, an air dryer is an essential component that removes the moisture from the compressed air used in plasma cutting. With so many air dryer options available in the market, choosing the best one for your plasma cutter can be challenging. In this article, we will review some of the top air dryers for plasma cutters, highlighting their features and benefits to help you make an informed decision.
Why do you need an air dryer for a plasma cutter?
An air dryer is typically required for plasma cutters that rely on an external air source, especially in environments where the air supply contains high moisture levels, oil, or other contaminants. This is because plasma cutting relies on a clean, dry air supply to ensure consistent and high-quality cuts, and any moisture or impurities in the air can adversely affect the cutting process.
One example where an air dryer may be required for a plasma cutter is in humid or tropical environments, where the air is likely to contain high levels of moisture. If the compressed air used by the plasma cutter is not properly dried, this moisture can cause the plasma arc to become unstable, leading to poor cut quality and damage to the machine. Additionally, moisture can cause corrosion and rusting of the internal components of the plasma cutter over time.
Another example where an air dryer may be necessary is in applications where the air supply is contaminated with oil or other pollutants, such as in industrial settings where the air may contain dust, smoke, or other airborne particles. In these cases, an air dryer can help to remove these contaminants from the air supply before it reaches the plasma cutter, ensuring a cleaner, drier air supply for better cutting performance and longevity of the machine.
Overall, if you are using a plasma cutter that relies on an external air source, it is important to consider the quality of your air supply and whether an air dryer may be necessary to ensure the best possible cutting performance and longevity of your machine.

Refrigerated dryers Vs Desiccant dryers
Refrigerated dryers and desiccant dryers are two types of air dryers that can be used to remove moisture from compressed air systems in plasma cutting applications. The main differences between these two types of dryers are their operating principles and the level of moisture removal they provide.
Refrigerated dryers and desiccant dryers are two common types of air dryers used to remove moisture from compressed air. Each type has its advantages and disadvantages, making them more suitable for specific applications and requirements. In the context of plasma cutting, clean and dry compressed air is crucial for optimal performance and prolonged consumable life. Below is a brief overview of each type, followed by a side-by-side comparison table.
Refrigerated Dryers
Refrigerated dryers use a refrigeration system to cool the compressed air, causing the moisture to condense and separate from the air. The condensed moisture is then drained away. Refrigerated dryers typically provide air with a pressure dew point (PDP) of around 35-50°F (2-10°C).
Desiccant Dryers
Desiccant dryers use a desiccant material, such as silica gel or activated alumina, to absorb moisture from the compressed air. The desiccant material needs to be periodically replaced or regenerated. Desiccant dryers can achieve much lower dew points than refrigerated dryers, typically down to -40°F (-40°C) or lower.
