The purity requirements for compressed air vary depending on the field of application and the specific requirements. Generally speaking, the purity requirements of compressed air mainly include particle size (cleanliness), moisture (dew point) and oil vapor (residual oil content). The following are detailed explanations and general requirements for these indicators:
particle size is a measure of the content of solid particles in compressed air. Different grades of compressed air have different requirements for particle size. Generally speaking, in industrial applications, the requirements for particle size may be relatively low; while in some high-precision applications, such as electronics, semiconductors, medicine and other fields, the requirements for particle size are very high. The specific values may depend on the actual requirements, for example, some high-precision applications may require a particle size of less than 0.1 microns.
moisture is a measure of the content of water vapor in compressed air, usually expressed by the dew point. The lower the dew point, the less the water vapor content in the compressed air, the higher the degree of drying of the air. Different industries have different requirements for dew point. For example, in some occasions that require dry air, such as painting, plastic processing, medical gases, etc., the dew point requirement may be lower than -40°C or even lower; and in some occasions that do not require high humidity, the dew point requirement may be relatively high.
oil vapor is a measure of the oil content in compressed air. The presence of oil vapor may adversely affect certain applications, such as contaminating products and affecting the normal operation of equipment. Therefore, many industries have strict requirements on the residual oil content in compressed air. Generally speaking, in industrial applications, the requirements for residual oil content may be relatively low, while in some high-precision applications, such as electronics, semiconductors, medicine and other fields, the requirements for residual oil content are very high. The specific values may depend on the actual requirements, for example, some high-precision applications may require a residual oil content of less than 0.01mg/Nm & sup3;.
for most industrial applications, the purity requirements of compressed air may be relatively low, but certain standards still need to be met to ensure smooth production. For example, in certain general industrial applications, it may be desirable to have a particle size of less than 1 micron, a dew point of less than -20°C, and a residual oil content of less than 0.1mg/Nm & sup3;. However, in some high-precision applications, such as electronics, semiconductors, medicine and other fields, the purity requirements of compressed air are very high, and more stringent indicators may be required.
our current compressed air purity level is to follow the ISO 8573-1 standard. This standard specifies the content levels of solid particles, water (liquid and steam) and oil (suspended solids and steam) in compressed air. According to this standard, the purity level of compressed air can be divided into 1 to 4 levels, each level corresponds to a different maximum value of pollutant content and particle size.
Generally speaking, the purity requirements of compressed air vary according to the application field and specific requirements. In practical applications, it is necessary to select the appropriate compressed air purity level according to actual needs, and take corresponding measures to ensure that the purity of compressed air meets the requirements.
Scroll air compressor and screw air compressor, they each have their own charm and advantages! To say whether the scroll air compressor is better than the screw air compressor, this is really a question of "radish and green vegetables, each has his own love. Vortex air compressor like an elegant dancer,
Oil-free air compressors and oil-free air compressors have their own advantages and applicable scenarios. There is no absolute "which is better", but needs to be judged according to specific application requirements. Oil-free air compressor: advantages: pure compressed air: no
The maintenance of frequency conversion screw air compressor involves many aspects. The following are some key maintenance steps and precautions: 1. Clean and replace the filter air filter element: It is recommended to maintain the air filter element once a week to ensure its filtering effect and prevent dust and dirt from entering
Oil and no oil refers to whether the compressed air contains oil. Oil air compressor is by the compressor special oil and air mixing, compression, separation into the purification equipment. Oil-free means that there is no lubricating oil in the compressor cavity. It is possible to lubricate with water or
