Details & Features
The I series delivers maximum air performance for professional applications - reliable, efficient, and easy to maintain. Its compact horizontal design, modern direct coupling, stainless steel components, and optimized cooling ensure long-lasting performance under extreme conditions. Equipped with B-CONTROL MICRO, external Purification system, and proven IK 22 compressor block, the series guarantees uncompromising breathing air quality and purity. Built for long operating cycles, the series minimizes operating costs through the use of low-wear components.
Compressor block
Our compressor blocks are based on decades of experience and development. An efficient air cooling system with large coolers and finned cylinders ensures optimal cooling. Robust industrial roller bearings, pressure lubrication, and fine oil filters minimize wear. Dynamically balanced drive units ensure smooth operation and long maintenance intervals.
B-CONTROL MICRO compressor control system
The B-CONTROL MICRO is a modern, user-friendly compressor control system with a color display that intelligently manages and reliably monitors all basic functions. Interaction between the user and the control system is intuitive and straightforward, with information displayed in clear text. Various languages are available. External signal transmitters can be connected at any time, and operation in a networked system or with an external display is also possible.
Kompressorsteuerung B-CONTROL SMART
Die B-CONTROL SMART ist eine leistungsstarke Kompressorsteuerung mit erweitertem Funktionsumfang, viel Speicher und IoT-Konnektivität via B-CLOUD. Sie unterstützt den Verbundbetrieb und bietet hohe Performance für anspruchsvolle Anwendungen. Wahlweise mit 3,5" Farbdisplay oder 7" Touchscreen ermöglicht sie intuitive Bedienung und sicheren Fernzugriff – eine zukunftssichere Lösung. 
B-DRAIN automatic condensate drain
The B-DRAIN condensate drain automatically discharges the water-oil mixture from the intermediate and final separators. Solenoid valves control the discharge individually and reliably. The gentle, controlled condensate release reduces pressure losses, saves energy, and increases efficiency. Compared to conventional solutions, B-DRAIN operates significantly more quietly.
B-LINK 4G
With an integrated WiFi or 4G router, compressor systems equipped with B-CONTROL MICRO can be wirelessly connected to the B-CLOUD. This enables stable remote access, reliable remote monitoring, and secure data transmission via WLAN or mobile networks. If required, the B-LINK 4G can be installed externally to optimize signal strength. It is designed for use in Europe, the Middle East, Africa, and the Asia-Pacific region.
Options
P 100/350 Purification system
The P 100 Purification system with three filter housings (four with CO conversion), oil and water separator, and pressure-retaining non-return valve ensures reliable breathing air purification in accordance with DIN EN 12021:2014¹ when using original BAUER filter cartridges.¹ Applies when properly maintained, installed in accordance with the operating manual, and when using the BAUER B-AEROGUARD if the CO₂ concentration exceeds the standard limits.P 120/350 Purification system
The P 120 Purification system with two filter housings (three with CO conversion), integrated oil and water separator, and pressure-retaining non-return valve enables reliable breathing air purification in accordance with DIN EN 12021:2014¹ when using original BAUER filter cartridges.¹ Applies when properly maintained, installed in accordance with the operating manual, and when using the BAUER B-AEROGUARD if the CO₂ concentration exceeds the standard limits.B-SECURUS filter monitoring
The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the moisture level in the molecular sieve and provides a timely indication when a cartridge replacement is required – either on the display or via the control unit. Once saturation is reached, the system automatically shuts down the unit. The B-SECURUS filter monitoring system can only be used in conjunction with the P 41, P 61, or P 81 Purification systems, as well as the external BAUER Purification systems.
B-CLOUD & B-APP
With BAUER B-CLOUD and the B-APP, users can keep an eye on their compressor system at all times, even remotely. Operating data, maintenance instructions, and status messages are transmitted and visualized in real time. This increases transparency, simplifies monitoring, and supports optimized maintenance planning. In addition, the stored operating data in the B-CLOUD is available for later analysis and system performance optimization.
B-LINK
Wi-Fi and 4G routers enable the wireless communication of the B-CONTROL MICRO with the B-CLOUD. They establish a reliable Wi-Fi or mobile network connection, allowing secure remote access to the compressor system.
B-CONTROL III
The B-CONTROL III is the premium control system for complex applications. Its 7-inch touchscreen display provides a user-friendly visualization of all operating data. Features such as a data logger, USB interface, Remote HMI, and protocols including OPC UA, Modbus, and CAN bus are integrated. The control system supports up to four compressors in a network and can be expanded flexibly.
Monitoring of intermediate pressures and intermediate stage temperatures
This monitoring system is ideal for continuous or fully automatic operation, as well as for systems without constant specialist supervision. If defined limit values are exceeded or undershot, an automatic shutdown is triggered. The current actual values are displayed in the B-CONTROL compressor control system.
Intermediate pressure gauge
Analog pressure gauges are installed at appropriate points of the compressor system and allow for easy monitoring of operating pressures. They support diagnostics and simplify maintenance work on the system.
Condensate collection system 60 l
The large condensate collection system centrally collects condensate produced during compression. An integrated float switch reliably monitors the fill level. Silencer and filter unit reduce noise and prevent odors in the working environment.
