Description
The Kaishan KRSB series rotary screw air compressor features belt drive construction, providing a highly reliable flow of compressed air and offering increased flexibility in pressure. Belt-driven compressors also operate with minimal loss of power from the motor to the pump, resulting in lower operating costs. Maintenance is required less frequently, and the compressor drive belt and other components can be easily serviced.
The KRSB series of compressors features an advanced belt drive system that eliminates energy loss and increases bearing life. A laminar flow inlet valve increases output while minimizing pressure drop, making performance more reliable while saving energy costs. An SKK series air end with an asymmetric 5 / 6 rotor profile and precision ground rotor machining allows for tighter clearances and improved performance. High-efficiency air intake filters offer excellent dust capture without impeding airflow, creating a more efficient system. The compressors also feature 316 stainless steel control tubing, a premium material with a longer life than nylon or copper, sophisticated controls with built-in alarms, and standard sound-deadening enclosures for quiet operation.
Belt-driven compressors are ideally suited for automotive repair shops and facilities, manufacturing operations, and heavy-duty industrial applications.
