1, The movement parts uses the lubricating oil splash lubrication system, guarantees normal work of the spare parts under the low temperature, and lengthens the service life. 2The air part of the compressor uses the thermostable anti-attrition material, guarantees the compressed air part is normally work in the oil-free lubrication situation. 3, With the unique body pressure in this series products can guarantee the lubricant of the movement part isolates completely with the part of compressed air enables the compression air to get truly Non-Lube. 4, Automatic unload system to ensure the machine starts safety under unload circs, this way can extend the using life of air compressor and protect the mainframe and motor. 5, The final discharge temperature of highly effective intercooling system and the after-cooling system is not higher than the ambient temperature 20 6, The rationality of overall construction as well as the high strength and the high quality spare part have guaranteed the machine stably reliable durable, can truly provide you all-weather 24 hours service
