BOGE SO 61-2 FW - SO 480-2 FW: Oil-free compressed air of the highest standard coupled with maximum efficiency and service life. . . . .


Direct drive: SO 61-2 FW - SO 480-2 FW (water cooled / frequency Controlled)


The SO series sets standards for efficient and reliable generation of absolutely oil-free compressed air. The intelligent design and innovative cooling principle offer clear advantages in day-to-day operation: lower energy costs, lower maintenance costs and greater reliability!
The water cooled screw compressors in this range use the latest technology to produce oil-free compressed air for sensitive applications - including the pharmaceutical, food and semiconductor industries.


Advantages at a glance:

  • Reliable supply of oil-free air thanks to ideal atmospheric separation of the gear unit and the compression chambers through the two-stage air end

  • High efficiency due to the precision-engineered asymmetrical screw profile

  • Wear-free running due to the use of synchronised rotor gears

  • Additional motor reserves for challenging operating conditions

  • Long service life of the motor due to installation in the cooling air intake section and PTC resistor protection

  • Maintenance-friendly due to intelligent design with components positioned for easy access

  • The high-quality materials and fewer wearing parts make for minimal maintenance costs and a long service life

  • Available with optional cowl cooler, heat recovery, or HOC adsorption dryer for practically energy-free compressed air drying to -40°C


With integrated frequency converter:

  • Energy savings through minimised idling times and reduced operating pressure

  • Optimum adjustment to compressed air demand

  • Faster response to changes in demand

  • Smooth operation and low compressor wear

  • Extended service life
