Super Silent version
Super Silent housing reduces the noise level of the compressor unit and makes the unit compatible for operation in working environments where noise is a key concern. For units in the (MINI-) VERTICUS series, Super Silent sound insulation can be retrofitted on request.

P 61 Purification system
When used in conjunction with original BAUER filter cartridges, the P 61 purification system with additional oil and water separator and pressure retention check valve can be relied upon for breathing air treatment conforming to DIN EN 12021:2014¹. A type-tested and sealed final pressure safety valve enables particularly high levels of operational safety to be achieved. 2400 m³ of air can be treated.

¹ If the units are maintained and installed correctly as described in the user manual and subject to the BAUER AERO-GUARD being used if CO₂ concentration in the intake air exceeds prescribed standard values.

B-APP
The B-APP allows remote access to BAUER compressors with the B-CONTROL MICRO control via the B-CLOUD. It offers useful features such as calculation tools, an integrated worldwide dealer search, news and videos about compressed air and BAUER compressors. Available in the App Store (iOS) and on Google Play (Android). Read more

Integrated gas measurement system B-DETECTION PLUS i
As an option, the B-DETECTION PLUS i gas measurement system can be integrated into the compressor. This permits the monitoring of all gases required by DIN EN 12021:2014. Thanks to the option for discharge to the outside in the event of short-term contamination and the shut-down of the compressor in the event of extended overruns of the limit values, observance of DIN EN 12021:2014 can be ensured at all times¹.

^{1 Measurement of humidity and total oil value (VOC) as option. Total oil measurement based only on volatile organic compounds (VOCs). Sensor calibration based on isobutene.}

B-SECURUS filter monitoring
The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the moisture in the molecular sieve. Read more

Monitoring the intermediate pressures and intermediate stage temperatures
This monitoring system is recommended for continuous operation and fully automated operation, as well as for compressor units that do not receive regular attention from specialist personnel. Monitoring tracks the minimum value of stage 1 (intermediate pressure only) and the maximum value of all compressor stages. The compressor unit shuts off if the values monitored fall below or exceed the permissible limit values. The actual value is displayed by the B-CONTROL compressor control unit.

Oil level monitoring
Optional oil level monitoring system for safely switching off the compressor unit when the oil level is low.
If the oil level reaches the minimum mark, this is displayed on the control and the compressor is switched off automatically for safety reasons. This option is particularly recommended for compressor units in continuous operation.

Particulate filter
In combination with the P41, P61 or P81 purification systems, an optional integrated particulate filter is available for effective protection against fine dust and other solid particles. This permits the reliable removal of particles in accordance with ISO 8573 class 2.

Connection for external intake system
When filling breathing air cylinders, the quality of the compressed air is dependent on the quality of the ambient air intake. Clean fresh air must be taken in from an external source in particular if there is a risk of exhaust gases (CO) and exhaust air from other units. A connection for an external suction line has been provided for this purpose.

B-CONTROL II
The BAUER B-CONTROL II is the advanced version of the basic compressor control B-CONTROL MICRO. Read more

Intermediate pressure gauge kit
The intermediate pressure gauges show the operating pressure of the individual compressor stages. This information about the pressure is used to check the corresponding stage valves (inlet and outlet) for leaks so that potential faults can be detected quickly. The intermediate pressure gauges are installed inside the compressor housing.

First stage separator
The installation of a separator after the first compressor stage is recommended for units operating in conditions where the moisture content of the ambient air is high (in tropical regions and for the effective compression of gases with a high moisture content. Read more

Filling device 4 × 200 bar
The filling device consists of four flexible UNIMAM high-pressure filling hoses and one filling valve each for 200 bar. The integrated final pressure gauge makes it easy to read off the final pressure.

Filling device 4 × 300 bar
The filling device consists of four flexible UNIMAM high-pressure filling hoses and one filling valve each for 300 bar. The integrated final pressure gauge makes it easy to read off the final pressure.

Pressure Reducer
The optional pressure reducer enables simultaneous filling of 200 and 300 bar cylinders.

Base frame
The compressor and up to 2 storage bottles each with a geometric capacity of 50 or 80 litres are installed on the extended base frame, making this a turnkey system.

Exhaust shaft
Two types of exhaust shaft are available for the installation of compressors in containers, housings or service rooms. Read more

Exhaust shaft with ventilation damper control
The exhaust shaft with ventilation damper control provides the means via which the exhaust air is discharged into the surrounding room or outdoors under controlled conditions and dependent on temperature. A temperature sensor measures the temperature in the room and controls the position of the ventilation dampers for optimised operation (only possible in conjunction with a Super-Silent housing).

Paint finish/Special paint finish
All frame parts of BAUER compressors are finished with a sophisticated powder coating. Read more

Other voltages/frequencies
All electric motors are available with other voltages and frequencies on request.

B-KOOL refrigeration dryer
In environments in which ambient temperatures are high in particular, the B-KOOL refrigeration dryer extends filter capacity almost beyond belief. Operators benefit from much lower filter cartridge usage and storage costs in addition to longer interruption-free operation. Read more

AERO-GUARD
Using the AERO-GUARD reduces the CO₂ content of the breathing air to approximately one-third of the intake value. The constantly increasing levels of CO₂ concentration in the air resulting from unfavourable environmental influences are making it more and more difficult for the operators of filling stations to be sure of achieving compliance with legally binding maximum limits for CO₂. With AERO-GUARD the operator is always on the safe side! Read more

External BAUER filling panels
Depending on requirements, filling panels are supplied with filling hoses or lever filling valves with 4, 6 or 10 filling valves. A stainless steel design can be provided as an option.

60 l condensate collection system
This convenient system provides a central collection point for the condensate (oil and water mixture) produced during the compression process inside the compressor. The condensate tank features an integrated float switch which can be relied upon to monitor the level of condensate in the tank and provides protection against overfilling. A combined silencer and filter unit prevents pollution caused by noise or odour.
