Compressed Air System Overview

Compressed air is often referred to as the "fourth utility" in manufacturing, standing alongside electricity, water, and natural gas in terms of its critical importance. Found in virtually every industrial facility, compressed air systems provide a versatile, reliable, and efficient source of power for a wide range of manufacturing processes. From pneumatic tools and material handling to instrumentation and process control, compressed air plays a vital role in ensuring smooth and efficient operations.


Despite its widespread use, compressed air is also one of the most expensive utilities, with inefficiencies leading to significant energy waste and higher operational costs. A well-designed and properly maintained compressed air system can enhance productivity, improve product quality, and reduce energy consumption, making it a key focus area for manufacturers looking to optimize efficiency and sustainability.


The Critical Role of Compressed Air in Manufacturing: 
Compressed air is integral to manufacturing processes across various industries, providing a safe, flexible, and efficient means of delivering power. Some of its key applications include:
1. Powering Pneumatic Tools - Manufacturers rely on compressed air to power tools such as drills, grinders, sanders, and wrenches. Pneumatic tools are preferred over electric alternatives due to their durability, high power-to-weight ratio, and ability to operate in hazardous environments where electrical sparks pose a risk.
2. Automation and Process Control - Compressed air is essential for robotic assembly lines, CNC machines, and automated control systems. Pneumatic actuators, solenoid valves, and cylinders use compressed air to facilitate precise movements and adjustments, improving manufacturing efficiency and consistency.
3. Material Handling and Conveying - Industries such as food processing, pharmaceuticals, and automotive manufacturing use compressed air for pneumatic conveying systems. These systems transport powders, granules, and small components efficiently and hygienically through pipelines, reducing manual handling and contamination risks.
4. Cooling and Drying - Compressed air is widely used for cooling and drying applications, such as removing moisture from metal parts after machining or drying printed surfaces in packaging lines. Air knives and blow-off nozzles provide targeted, high-velocity air streams for effective drying and debris removal.
5. Instrumentation and Quality Control - Precision air pressure is vital for operating gauges, sensors, and laboratory instruments. Many manufacturing quality control processes rely on compressed air to ensure consistency, such as pressure testing of components and leak detection in sealed products.

Challenges and Inefficiencies in Compressed Air Systems - Despite its widespread use, compressed air is one of the least efficient forms of energy due to conversion losses, leaks, and pressure drops. The biggest challenges manufacturers face include:

Energy Consumption: Producing compressed air is energy-intensive, often accounting for 10-30% of a facility’s electricity use.
Leaks and Wastage: Up to 30% of compressed air in a typical system is lost due to leaks, poor maintenance, and inefficient operation.
Inadequate System Design: Improperly sized compressors, piping restrictions, and insufficient storage can lead to pressure fluctuations, inefficiencies, and increased wear on equipment.
Moisture and Contaminants: Unfiltered air can cause corrosion, clogging, and damage to sensitive pneumatic components, reducing system reliability.

Inline Compressed Air Meters

Inline compressed air meters are essential tools for monitoring and managing compressed air usage in industrial and manufacturing settings. These meters are installed directly within the pipeline to measure air flow, pressure, and consumption in real time, helping businesses optimize efficiency and reduce energy waste.

Compressed air is one of the most expensive utilities in an industrial facility, often accounting for up to 30% of electricity costs. Without proper monitoring, leaks, inefficient usage, and system imbalances can lead to significant financial and energy losses. By implementing inline compressed air meters, facilities can gain accurate insights into air consumption, enabling better system management, cost savings, and sustainability improvements.

Metering Data integration

Data Integration and Dashboarding

Energy monitoring was never this easy with our cloud based monitoring solutions. View your compressed air system from anywhere in the world, and involve experts when needed.  Your service provider can now have a first look and analyze your measurement data without coming to your factory, e.g. in case of issues or for advice on system improvements and energy savings.


Integrate system pressure, temperature and flow data from the installed meters into the cloud dashboard for easy data management. 


We believe that all metered compressed air flow, pressure, temperature, compressor cycling data should always be integrated to either a site or cloud based SCADA to provide optimal data access and value to the facility. A non-integrated metering system has limited value since access to the meters are typically challenging and requires someone to physically read their data. These spot checks provide no guidance or visibility on the system's operations the many other minutes / hours of the day. Once integrated, data is stored and can be retrieved with ease for analysis and performance checks.
