Description
Boge S 75-2 Rotary Screw Air Compressor – 55 kW
The Boge S 75-2 is a high-performance rotary screw air compressor, engineered for reliable and efficient compressed air delivery in industrial settings. Manufactured in 2005, it features a main motor rated at 55 kW and an additional auxiliary motor of 2.2 kW, operating at a speed of 3000 RPM. It delivers a maximum free air delivery (FAD) of 9.33 m³/min at a maximum pressure of 8 bar, making it suitable for a wide range of manufacturing and processing applications.
While the cooling system and drive type are not explicitly mentioned, the S series from Boge typically uses an oil-lubricated, air-cooled, and direct or belt-driven system. The assumed voltage rating is 400V with a frequency of 50 Hz, which is standard for industrial power supplies in Europe and other regions.
The ingress protection is typically IP54 or IP55, and the motor is built with Class F insulation, supporting operation in ambient temperatures of -10°C to +40°C, and altitudes up to 1000 meters above sea level. The sound level is generally within 65–75 dB(A), depending on enclosure design.
