Overview
LGCY-19/21-21/18 is a portable diesel screw air compressor from Kaishan's LGCY two-stage compression series. It delivers 19-21 m³/min across a discharge-pressure range of 2.1-1.8 MPa, driven by a 260.0 HP Yuchai engine, and weighs 3600 kg.
Key highlights
- ✓SKY patented screw air end: proprietary rotor profile and heavy-duty design with SKY bearings, direct drive, energy-saving principle and innovative design.
- ✓Dedicated engine for strong power: matched with Yuchai, Cummins and other heavy-duty dedicated diesel engines, so the machine runs in its optimal combustion range across the whole operating envelope, giving higher reliability, stronger power and better fuel economy.
- ✓Multi-stage air filtration system: effectively prevents harmful dust particles in the environment from affecting the engine; the air path's precision filter element removes residual dust so the air end is not worn, and the safety core lets the machine keep filtering while the element is being serviced, ensuring safe operation.
- ✓High-efficiency cooling system: independent oil, water and air coolers with large-diameter fans, designed for cold and hot environments.
- ✓Three-stage oil-air separation system: reduces oil carryover from the air end, keeps the oil content of the delivered compressed air below 3 ppm, and clean compressed air benefits the safe operation of the equipment that uses it.
- ✓Low-temperature starting system (optional): a heater warms the engine coolant, and the heat exchanger warms the fuel in the tank so it can be pumped, burnt and supplied; the continuous heat transfer keeps coolant, engine oil and lubricating oil at working temperature, ensuring reliable starting in severe cold and high-altitude environments.
- ✓Remote start/stop, monitoring and positioning system (optional).
