Overview
The BK series belt-driven screw air compressor is one of Kaishan's flagship products, using Kaishan's patented SKY rotor profile, built-in oil separation system, low-consumption high-efficiency motor and high-efficiency inlet control valve, with a user-friendly HMI display and control system. Power coverage is 7.5-132 kW, pressure 0.8-1.3 MPa, and G models are the silenced versions.
Key highlights
- ✓Built-in oil separation system: internal oil-air separation gives good separation, low oil content in the compressed air, lower oil consumption and longer air-end life.
- ✓Low-consumption high-efficiency motor: high starting torque, IP23 protection, Class F insulation and a built-in oil-filling device allowing oil top-up without stopping.
- ✓High-efficiency inlet control valve: ON/OFF control with a check valve and anti-oil-spray design for precise inlet regulation and avoidance of load energy waste.
- ✓User-friendly HMI control system: easy operation and 24-hour unattended running; Chinese prompts for maintenance/inspection when abnormal conditions occur; multiple-unit interlock control and remote diagnosis interface.
- ✓G silenced models: specially designed acoustic enclosure for noise-sensitive locations such as hospitals, schools and office areas.
- ✓High-quality core components: SKY patented rotor air-end and SKF bearings for long life and high reliability.
- ✓Full 7.5-132 kW power range: from small workshops to large factories, with a wide model choice.
- ✓Export quality: meets CE, ASME and other international standards and can be exported to 60+ countries and regions.
