SO 61 FA – SO 126 FA

Oil-free compressed air of the highest standard coupled with maximum efficiency and service life

Direct drive: SO 61 FA – SO 126 FA (air cooled / frequency controlled)

The SO series sets standards for efficient and reliable generation of absolutely oil-free compressed air. Its intelligent design and innovative cooling principle offer clear advantages in day-to-day operation: lower energy costs, lower maintenance costs and greater reliability!
The air 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
