Air compressor has oil and no oil which is expensive

When comparing which is more expensive with oil and no oil in the air compressor, it can be analyzed from the following aspects:

1. purchase cost

oil-free air compressors are relatively expensive due to their high manufacturing process, material costs and technical difficulties. Generally speaking, the price of oil-free air compressor will be more than 10000 yuan, or even higher. Take a pressure of 8kgf/cm and a flow rate of 1.2m & sup3;/min, an air compressor with a power of 15kW, for example, the price of an oil-free air compressor is generally above 20000 yuan.

Oil injection air compressor (that is, oil air compressor) manufacturing process is relatively simple, material cost and technical difficulty is low, so the price is generally cheaper, usually below 10000 yuan. For air compressors with the same parameters and specifications, the price of oil-injected air compressors may be around 10000 yuan, which is significantly lower than that of oil-free air compressors.

2. operating costs

oil-free air compressor does not need to use lubricating oil during operation, so the cost of replacing lubricating oil and other accessories is eliminated. At the same time, due to its low noise and high reliability during operation, the maintenance cost is relatively low.

Oil-injected air compressors need to replace lubricating oil regularly and deal with problems such as oil mist and gas pollution, which will increase certain operating costs.

In summary, from the purchase cost point of view, the price of oil-free air compressor is usually higher than that of oil-injected air compressor. However, in terms of operating costs, oil-free air compressors may have advantages due to the removal of lubricating oil and other expenses. Therefore, when choosing an air compressor, in addition to considering the purchase cost, it is also necessary to comprehensively consider its operating cost and specific application requirements.

In addition, it is worth noting that the price of air compressors of different brands and models will also vary. Therefore, in the actual purchase, it is recommended to compare the choice according to their own needs and budget.
