Good or bad depends on the occasion of use and the actual working conditions.
In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor.
But the oil-free air compressor is much more expensive and the maintenance cost is higher.
If it is used for purging, machining, manufacturing and power use, it is possible to choose an air compressor with oil and micro oil. Such as spraying, steel, electricity, hardware, mining, ceramics, textiles, machinery, etc. are widely used.
The difference between oil and no oil
oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, the oil content is used to distinguish the oil and no oil in the air compressor.
At present, the air compressor model with large displacement and full oil-free can adopt the scheme of water lubricated screw air compressor.
Water jet screw compressor does not need pure water, softened water is enough. Tap water must not be used directly, it will scale and corrode and wear. Pure water is too expensive and unnecessary. Softened water is the most cost-effective. The water-lubricated air compressor is used with softened water. The machine has long life, low maintenance cost, and no oil pollution. It is the most worry-free combination.
The output pressure of the air compressor usually varies according to the use scenario and demand. Generally speaking, the pressure range of the air compressor is relatively wide and can be adapted to different application scenarios. Some common pressure ranges are as follows:
The air time of the air compressor can be adjusted. There are mainly the following methods to adjust the air time of the air compressor: Adjust the pressure switch: The pressure switch is an important part of the air compressor. By adjusting the adjustment knob on the pressure switch, the start of the air compressor can be changed
Oil-free air compressor does not need to add lubricating oil during operation. This kind of air compressor usually uses special design and materials to ensure that it can work normally without lubricating oil. However, this does not mean that oil-free air compressors do not require any lubrication at all.
The problem of low oil pressure of dry oil-free air compressor is actually a misunderstanding, because the dry oil-free air compressor itself does not use lubricating oil, so there is no traditional concept of "oil pressure. However, the "oil pressure" mentioned here
In industrial production, especially in precision manufacturing and medical fields, the purity of compressed air is very important. The total number of colonies is a key indicator to evaluate the degree of microbial contamination of compressed air, and its detection method is particularly important.

Air compressors are common equipment used in industrial production to compress air to provide power or perform other process operations. Screw air compressor is one of the widely used types, but in addition to the screw type, there are several main types of air compressor: piston type air compressor
Fermentation air quality requirements standards mainly include the following aspects: Microorganism content: microorganisms in the air (including bacteria, molds and yeasts, etc.) play an important role in the fermentation process, but their content needs to be controlled within an appropriate range to avoid
Shanghai Granklin Group and its oil-free low-pressure screw air compressor have performed well in the industry and are one of your preferences. The following is a detailed analysis: 1. Shanghai Granklin Group strength enterprise background: Founded in 2009, it is located in Shanghai Baoshan District Robot Industrial Park, accounting
The pressure of the general air compressor depends on the specific application requirements, and there will be different pressure requirements in different scenarios. The following are some common air compressor pressure ranges: low pressure air compressor: exhaust pressure is usually below 1.6MPa(16 bar), which is suitable for pressure requirements
