BOGE SO Series Oil-Free Screw Compressors: The progressive alternative. . . . .


BOGE SO. . . . Whenever oil-free air is required for specialised production processes - choose the SO Series oil-free generation.


If compressed air is oil-free from the start then you won’t have to purify it at the end. All BOGE oil-free screw compressors are divided into three clearly defined sections. This intelligent layout ensures longer service life and greater availability. Easy unhindered access for inspection and replacement without having to remove other components. A very maintenance-friendly concept.


BOGE forced air circulation (i.e water cooled system SO 150 - 480) . . . .


  • Control electronics, electrical components and the motor are all located in the coolest part of the machine.

  • Neatly laid out, allowing easy access to the two stage airends.

  • The aftercoolers are situated one above the other in their own section.

SO with frequency control . . . 


Frequency regulation is optional. This way only the required amount of air is generated at a constant pressure thus saving energy. The frequency converter is either in a separate cabinet or integrated into the compressor. Use the SO when there is a fluctuating demand or as a stand alone peak load compressor - ideally in conjunction with BOGE turbo compressors.

PRIME - the state-of-the-art highly efficient BOGE control . . .


PRIME is the state-of-the-art highly efficient BOGE control. A large-scale, back-lit LC display with clear text output shows the fault and maintenance messages, operating modes and all operating parameters clearly arranged in three main displays. Volume flow and pressure characteristics are graphically displayed and freely scalable. Due to the modular design optional displays - like e.g. pressure dew point - can be easily added.
PRIME control has an integrated real-time clock and a switch clock function enabling it to evenly control external equipment. Communication is achieved via RS 485 interfaces or potential-free signalling contacts.

BOGE airends, the compressors’ heart . . .


All the BOGE oil-free screw compressors use a two stage airend that guarantees very low specific power consumption. The motor drives the separate flange mounted stages - by belt or direct drive. Both compressor stages are designed for full load and intermittend operation. The shafts are continuously sealed by a series of chrome steel labyrinths and atmospheric venting. Specially plasma treated rotor surfaces are wear free and absolutely corrosion resistant.

BOGE airend bearings, dependable & durable . . .


The airends are designed for demanding operating conditions and are fitted with amply sized roller bearings. These special bearings eliminate the need for addtional axial thrust compensation, thus eliminating a potential source of problems.
