What are the brands of water lubricated air compressors
The brand selection of water lubricated air compressor is actually quite wide, which can be roughly divided into several echelons. I will help you sort it out according to the place of origin and positioning.
First, the international veteran. Europe has a Swedish century-old industrial brand, in the field of oil-free air compressor layout very early, deep technology accumulation, product line coverage is very complete. Germany has a family business that specializes in compressed air equipment and has mature solutions for water-lubricated oil-free models. The UK has a brand derived from an established industrial group that continues to operate independently after being acquired by a larger international group, and the water lubrication series is one of its main directions. There are two or three established compressor manufacturers in the United States, one of which is now owned by the Japanese group, and the other also has a water-lubricated oil-free product line. The common characteristics of these international brands are mature technology and perfect global service network, but the price is usually high.
Besides domestic brands. In recent years, domestic water-lubricated air compressors have made rapid progress, mainly in several regions. There are several manufacturers specializing in oil-free machines in the Yangtze River Delta. Some only do water lubrication as a technical route, and some do dry oil-free and water lubrication at the same time. The products are used more in the food, medicine, and electronics industries. The Pearl River Delta also has a brand that specializes in intelligent compressed air systems, combining water-lubricated air compressors with Internet of Things monitoring. There is a manufacturer in southwest China that has optimized high humidity and complex working conditions, and has a good reputation in traditional industries such as chemical industry and mining industry. There is also a brand in Shanghai, which focuses on energy conservation and intelligence, and is widely used in the pharmaceutical industry. Zhejiang has a listed company background manufacturers, the core components of their own, the industrial chain is relatively complete. There are also some companies that act as agents and services for international brands, as well as their own product lines.
When choosing a brand, the working logic of the water-lubricated air compressor itself is as follows: when the screw inside the machine rotates the compressed air, it does not use oil to reduce friction, but uses water. Water lubricates the screw while taking away the heat generated by compression, so there is no oil in the air. Because there is no oil, no oil change or waste oil treatment in the later period, the condensed water discharged is clean water, no sludge will accumulate in the pipeline, and maintenance is much simpler than that of the oil injection machine.
How to choose, give you a few judgment direction. First look at your industry, food, medicine, electronics and other high air quality requirements, give priority to the oil-free certification of the brand. Second, look at the after-sales network. Although the maintenance of water-lubricated air compressors is simple, in case of problems that need to be handled by professionals, brands with local service outlets are more reliable. Third, look at energy efficiency. Now good water lubrication models are generally equipped with frequency conversion technology, and there is a big difference in electricity charges after long-term use. Fourth, look at the budget. International brands are expensive but stable. Domestic brands are cost-effective and respond quickly. Just weigh them according to your own situation.
The water-lubricated screw air compressor produced by Shanghai Granklin Group has a large number of cases to visit in China and around the world. When selecting the air compressor, you may wish to refer to it.
