Pneumatic separators—also known as water separators—are essential pneumatic air preparation components that help eliminate moisture and mist from compressed air systems. They also serve a dual function by filtering out unwanted, and potentially harmful, contaminants such as dust and debris.
Why use pneumatic separators?
These devices play a critical role in maintaining the efficiency and reliability of pneumatic and compressed air systems. If moisture is not effectively removed, it can lead to condensation within pipes, tools, and instrumentation—causing wear, corrosion, and system malfunctions over time.
The presence of condensed water contributes to corrosion in both storage tanks and distribution lines. It can also lead to degradation of machinery and compromise the quality of end products. Additionally, moisture can strip away pre-applied lubricants on valves and actuators, shortening their service life. Overall, water buildup in pneumatic systems results in decreased productivity and increased maintenance requirements.
Key features and advantages of pneumatic separators
Some notable features and advantages of using pneumatic separators include:
Compact and lightweight construction for easy installation and repositioning
Automatic drainage system, offering hassle-free operation with minimal upkeep
Engineered to resist clogging for consistent performance
