The Kaishan BOREAS Series, also known as the BK Series, is a line of industrial screw air compressors designed for low-power, cost-effective compressed air solutions. These compressors are available in various configurations including belt-driven (typically 11 kW to 18.5 kW), optional gear-driven, and direct-driven models ranging from 7.5 kW up to 132 kW. They operate with discharge pressures from 0.8 MPa to 1.3 MPa (approximately 116 to 189 psi) and offer variable frequency options for energy efficiency.

Key specifications and features of the BOREAS (BK) series include:

• Power range from about 7.5 kW to 132 kW.

• Displacement (air delivery volume) varies by model, starting as low as 1.1 m³/min and going up to around 24 m³/min and above.

• Pressure ratings configurable between 0.8 MPa (116 psi), 1.0 MPa, and 1.3 MPa (189 psi) depending on the model.

• Multiple exhaust connection sizes depending on model.

• Designed with advanced rotor profiles for improved efficiency and reliability, featuring slow-speed rotors that reduce noise, vibration, and wear.

• The compressors are well-suited for environments with demanding temperature and humidity conditions due to excellent cooling design.

• Compact dimensions and relatively lightweight for easy installation without special foundations in many cases.

• Noise levels are designed to be relatively low due to advanced vibration isolation and sound reduction technologies.

• They include features like automatic load/unload control and can run at variable frequencies for energy saving.
