    LG Series - Rotary Screw Air Compressors:


    Kaishan offers complete, high quality, low cost LG series rotary screw air compressors. They come configured as belt driven (7.5kw -18.5kw), optional gear driven, direct driven (22kw –200kw) with discharge pressures from 0.7Mpa to 1.3Mpa. Water-cooled and aircooled units are available. PLC is a common feature for the LG series and is included in VSD packages.

     


    The Design Features of the LG Series


    1. Our single-stage rotary screw airend is engineered for its durability. Larger rotors allows for bigger bearings, 30%-50% slower rotor speeds results in less power consumption, lower sound levels and reduced maintenance cost.


    2. Our one piece bearing housing ensures both rotors are ridgely held by the bearings in proper alignment during transient periods such as machine startups/shutdowns or load changes.


    3. SKF bearings and SEALTECH bearing seals are utilized in all airends.


    4. All of our compressors have the latest inlet valve, airend air discharge port and oil inlet port design.


    5. Lower sound (dBA) emission level than most of our competitors results in less sound pollution.


    6. The axial and rotational loadings are supported by different bearings for better stiffness and less transition noise.


    7. Simple package design requires only minimum maintenance for optimum performance.


    8. Continuous cooling and circulation of lubricating oil, ensures long airend operating life.

     

     

    The Design Features of the LG Series

     

    The system adopts stepless capacity regulation of 0-100%. When the gas consumption is reduced, exhaust volume decreases, the motor current decreases at the same time; when no gas, air compressor run empty, empty for too long the automatic shutdown. When the gas consumption increases, the resumption of heavy truck. Energy-saving effect is optimal.


    Good environment adaptability
    Design of cooling system of extraordinary, especially suitable for high temperature, high humidity environment in asia.
    Vibration and noise reduction measures excellent, make Kaishan brand screw air compressor installation without special foundation, just leave the minimum ventilation and maintenance space, can arrange your compressor.
