G – Series: Mini-Verticus & Verticus

SKU: G Series: Mini-Verticus & Verticus

Bauer’s G series range of compressors provides innovative high-pressure system technology for the recovery, decanting and compression of helium, argon and other noble gases.

Optimised for helium and other noble gases, MINI-VERTICUS and VERTICUS are the gas-tight and helium-tight classics in the successful BAUER G-series.

The new MINI-VERTICUS and VERTICUS combine the legendary BAUER compressor blocks with improved components and ultra-modern design! During the redesign, the focus was on ergonomics, making operation as easy as possible, reducing noise and boosting efficiency.

All control elements that are important for everyday operation are ergonomically arranged and easily accessible from the front.

The advanced B-CONTROL MICRO is more powerful and ready to communicate with the B-APP for remotely controlling and monitoring the compressor.

Recirculation of blowby and lost gas from the automatic condensate drain into the intake buffer combined with efficient encapsulation of the safety valves effectively minimises gas losses.

Low speeds and optimised grading of the compressors provide the basis for the very best compression ratios for the compression of noble gases.

Please refer to Equipment Options for upgrades available for these models


  • Now significantly quieter: thanks to the new anti-vibration frame and noise-optimised Super Silent housing
  • Compact dimensions: For installation wherever, space is at a premium
  • Ergonomic design: optimum accessibility and operation
  • B-DRAIN: The new automatic condensate drain is quieter and saves energy
  • Very easy to maintain: The tension of the V-belt does not have to be adjusted
Super Silent version
Super Silent housing reduces the noise level of the compressor unit and enables an exhaust shaft to be used. For units in the MINI-VERTICUS & VERTICUS series, Super-Silent sound insulation can be retrofitted on request.


The BAUER B-CONTROL II compressor control is the extended version of the B-CONTROL MICRO basic compressor control.
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 II 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.
B-APP allows users to remotely control and monitor compressors with the new B-CONTROL MICRO. B-APP also offers additional features such as product-specific news, videos, an integrated dealer search function and calculation tools. Available in the AppStore (iOS) and on GooglePlay (Android).
P 61 Purification system
The units in the MINI-VERTICUS & VERTICUS series can be supplied with the P 61 purification system integrated as an option. Clean air and gas qualities meeting the requirements of ISO 8573-1 (among others) can be achieved.
P 81 Purification system
The units in the MINI-VERTICUS & VERTICUS series can be supplied with the P 81 purification system integrated as an option. This system doubles the intervals for changing cartridges compared with the P 61 purification system and meets the requirements of more far-reaching treatment standards.
Particulate filter
An integrated particulate filter is offered as an option in conjunction with the P61 and P81 purification systems, to remove particulates safely in compliance with industrial requirements under ISO 8573 class 2.
B-SECURUS filter monitoring
The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the moisture in the molecular sieve.
Intermediate pressure gauges
Analogue pressure gauges mounted on the compressor unit in a suitable location. They make it easy to check, diagnose and maintain the unit.
Intake pressure reduction
Intake pressure reduction ensures that the compressor takes in the gas at the appropriate pressure. The level of intake pressure reduction is adjusted according to prevailing gas pressure and required intake pressure. Integrated safety valves and pressure monitoring effectively ensure that intake pressure does not fall below or above the permissible level.
Exhaust shaft
Two types of exhaust shaft are available for the installation of compressors in containers, housings or service rooms.
