Air compressor KOMPBERG® BSDK5

electricstationaryoil-lubricated

Overview
The KOMPBERG® BSDK5 with integrated refrigeration dryer AD delivers high-quality, dry compressed air in a single, space-saving system. Designed with a robust, low-speed air end, this compressor provides quiet operation and long service life. The direct-drive electric motor is coupled to the main rotor without belts or gear transmission, minimizing energy loss and reducing routine maintenance compared with conventional belt-driven units. The built-in dryer efficiently removes moisture from the air stream, protecting downstream equipment and maintaining stable air quality without the need for a separate drying unit. Smart control options—ranging from pressure-based on/off regulation to advanced variable-speed adjustment—allow the machine to fine-tune output in real time for optimal efficiency and lower operating costs.

Key features

• Integrated refrigeration dryer AD for dry compressed air in a compact footprint
• Large low-speed air end for reduced noise and extended service life
• Direct-drive electric motor (no belts or gearbox) to minimize energy loss and maintenance
• Smart control options: on/off pressure control, suction regulator, or advanced continuous (variable-speed) regulation
• Low noise level compared with piston compressors and many competitors
