Why Choose Water-lubricated Air Compressor?
Water-lubricated oil-free screw air compressor VS Dry type oil-free screw air compressor
| Water lubricated oil-free machine | Dry oil-free machine | |
| Operational reliability | Water lubrication reduces wear and heat accumulation and provides stable operation. | No lubricant leads to higher wear and heat accumulation, which may increase the risk of failure. |
| noise | The water lubrication system reduces the vibration and noise of the machine and provides a quieter working environment. | The non-lubricating system produces more vibration and noise, and the working environment is noisy. |
| compression efficiency | Water cools compressed air, improves energy utilization efficiency and produces more compressed air. | Lack of water cooling effect, energy utilization efficiency is slightly lower than that of water lubricator. |
| air quality | Water filters impurities in the air and provides clean and pure compressed air. | The waterless filtration mechanism may contain more impurities and the air quality is slightly lower. |
| energy saving and environmental protection | The water lubrication system does not need lubricating oil, which avoids the consumption and discharge of lubricating oil and meets the requirements of energy saving and environmental protection. | Key parts need oil for lubrication. |
| life | Water lubrication reduces the wear of screws and bearings and prolongs the service life of equipment. | Depending on the rotor coating, the service life is uncontrollable. |
| Wide application range | It is suitable for industries that require high quality of compressed air, such as food and pharmacy. | Because of the risk of oil leakage after long-term use, it is not suitable for industries with high requirements for air pharmacy. |
| Water lubricated oil-free machine | Dry oil-free machine | |
| compress mode | Water seal, high efficiency | Gaps exist and the efficiency is low. |
| Transmission mode | The motor is directly connected, and the mechanical loss is small. | Speed-increasing gear, large mechanical loss |
| Compression chamber temperature | Low temperature compression (less than 50 degrees Celsius) | High temperature compression (200 ~ 300 degrees Celsius) |
| Stress situation | Ideal force balance compression, the highest pressure can reach 4.0Mpa. | Axial force and radial force are unbalanced, which can not provide high pressure compressed air. |
| rotation speed | The rotating speed is only 3000 rpm, with low noise and long service life of the parts. | Up to 10,000-20,000 rpm, with low bearing life. |
| Water lubricated oil-free machine | Dry oil-free machine | |
| Oil free safety | Adopt water lubrication, life-long oil-free guarantee. | The aging of sealing ring will lead to the risk of oil leakage. |
| moisture/water content | Low temperature and low moisture content of compressed air. | High temperature and high moisture content of compressed air. |
| Impurity situation | Pure water is used to clean compressed air, and at the same time, water filtration and air filtration are used to filter compressed air, so the impurities in compressed air are low. | No filtration system, high impurity content. |
| Impurity situation | Pure water is used to clean compressed air, and at the same time, water filtration and air filtration are used to filter compressed air, so the impurities in compressed air are low. | No filtration system, high impurity content. |
