1, imported brands are more expensive than domestic brands, but the cost performance of domestic brands is definitely not bad. Many domestic brands are the first choice for most small and medium-sized enterprises because of their high quality and low price. Air compressors are also high in power and expensive in price.
2. Oil-free air compressors are much more expensive than ordinary air compressors with the same power, and are generally suitable for food, medicine, precision instruments and other fields. Frequency conversion air compressor is also more expensive than ordinary air compressor because it has the advantages of higher efficiency and more energy saving.
3. How much power air compressor do you need to buy depends on its gas output, which can not meet the normal production of the factory and will cause waste. In particular, it should be emphasized that some industries do not require high pressure, and only need to have a pressure within 0.5MPA, such as textile and chemical fiber, packaging, chemical industry and hardware products. The average air compressor on the market is 0.8MPA, which will cause great energy waste. At this time, you can choose a series of low-pressure and large-displacement air compressors.
4. Because the air compressor runs under the conditions of high temperature, high pressure and high speed, it is very important to maintain the machine, so you must choose a regular manufacturer when choosing to ensure worry-free after sale.
