airleader Master 4
The advanced standard in compressor control
The Airleader Master 4 is the heart of a modern compressor station and can control up to 16 compressors, including two (optionally up to eight) variable speed (VSD) units. This advanced control ensures that only the necessary number of compressors is running, eliminating unnecessary idling and maximising the efficiency of the entire station. This precise control makes it possible to achieve a pressure band of only +/- 0.15 bar with minimal switching frequency, contributing to significant energy savings and gentle use of the compressors.

User-friendly control and visualisation
The Airleader Master 4 is operated via a standard 10-inch colour touchscreen or an integrated web interface, which can be connected to smart devices (laptop, tablet, smartphone) via the RJ 45 ETHERNET interface or the standard Wi-Fi hotspot. The standard web server visualisation provides a transparent overview of the operating status of the compressed air station, identifies inefficient compressors and enables targeted measures to improve efficiency.
Data security and reliable backup
All operationally relevant data is stored securely on the customer’s own server, which is shielded from external access and does not allow any data transfer to external servers. This protects sensitive operating data and safeguards user privacy. For additional security, the data is also backed up in the internal memory of the Airleader Master 4 to prevent data loss in the event of server problems or later installations.
Self-learning optimisation and simple operation
The Airleader Master 4 adapts through self-learning to changes in network volume and compressor dynamics. Control is based on simple inputs such as the compressor delivery volumes and the desired pressure band. The Airleader Master 4 then takes care of fine-tuning to keep the system at an optimal level at all times.
Manufacturer-independent flexibility
This control unit ensures that the most efficient combination of compressors is always in operation, regardless of manufacturer. The system works with intelligent pressure band control and calculates dynamic adjustments that reduce unnecessary switching cycles and thus minimise operating costs.

Standard online visualisation and monitoring
Airleader’s online visualisation provides comprehensive insight into the operation of your compressed air systems. It shows consumption, pressure and compressor status instantly in a clear overall diagram. The high-resolution display updates 10 times per second, allowing precise analysis and the identification of short peaks thanks to an extreme zoom function.
A wide range of sensors can be integrated and their data visualised in high resolution, with limit violations automatically generating messages. Specific power and energy balance are monitored continuously, with automatic notifications when costs are exceeded.
Long-term monitoring, preventive maintenance planning and easy-to-understand statistics on load and idle times are integrated as standard. All data is stored for 20 years and is accessible via the web server without loss of speed, with several users able to access it at the same time.
Summary
The Airleader Master 4 is a leader in compressor control, optimised for up to 16 compressors. Demand-based control prevents unnecessary idling and thus improves energy efficiency. It achieves a pressure band of +/- 0.15 bar, which extends the service life of the compressors.
It is operated via a 10-inch touchscreen or a web interface, which makes operation simple. All data is stored securely on the customer’s own server to prevent external access. The Airleader Master 4 offers a reliable solution for industrial applications that need an efficient compressed air supply.
Frequently asked questions
How many compressors does the Airleader Master 4 control?
Up to 16 compressors, including two (optionally up to eight) variable speed units.
Does the Airleader Master 4 work with compressors from different manufacturers?
Yes. Regardless of manufacturer, the control ensures that the most efficient combination of compressors is always in operation.
How does the Airleader Master 4 save energy?
It runs only the necessary number of compressors and avoids unnecessary idling. The pressure band of +/- 0.15 bar with minimal switching frequency is also gentle on the compressors.
How is the Airleader Master 4 operated?
Via a 10-inch colour touchscreen or the integrated web interface. You can access it via RJ45 Ethernet or the Wi-Fi hotspot with a laptop, tablet or smartphone.
What do I need to set during commissioning?
Only the compressor delivery volumes and the desired pressure band. The Airleader Master 4 handles the fine-tuning through self-learning.
Where is the operating data stored?
On your own server, shielded from external access. In addition, the device’s internal memory backs up the data, with capacity for 20 years.
What housing is the Airleader Master 4 available in?
In a plastic housing or in a metal control cabinet measuring 500 x 500 x 210 mm.
Can vacuum or high-pressure networks also be integrated?
Yes, as an option. Possible ranges are vacuum from 0 to 1,000 mbar, low pressure from 0 to 2.5 bar and high pressure up to 50, 100 or 400 bar, plus part-load compressors and turbo compressors.
