BOGE S-4 series screw compressors 

BOGE has expanded the fourth generation of the S series, which now covers the entire 45 to 150 kW performance range. All models are characterised by quiet operations and good efficiency values. The compressors generate high free air delivery at low specific power consumption. The energy use of the new 75 kW compressor has been reduced by over 12% compared with its predecessor, while the free air delivery has increased by almost 9%. The generously sized components reduce internal pressure losses, and with a footprint of just 1.20 x 2.00 m, the housing of the new models is smaller than older models. The compressors come with the high-performance, low-energy IE4 motors and permanent magnet motors fitted as the industry standard.

The vertical oil separation concept contributes to low residual oil content, minimal pressure losses and a long service life, while the internal cartridge is quick and easy to remove and replace. Maintenance takes place from two sides with just a few simple movements — the intake filter is accessible and both the oil and air coolers can easily be removed and cleaned.
