I have been engaged in the theoretical research of laboratory air compressors for many years. I now provide some suggestions on how to correctly choose laboratory air compressors for your reference.
Laboratory air compressor selection criteria
1. Parameter matching work pressure control: What is the air pressure required for work? At present, most of the air compressors used in the laboratory are adjustable in 0-8 BAR (about 0-8 kg), which meets the air pressure requirements of most experimental equipment.
Stable and continuous displacement (usually expressed in L/MIN): refers to the number of liters per minute of gas flow at rated working pressure, and to ensure a constant steady flow of gas, so the air compressor operating stability requirements are very high. At present, many brands on the market are mixed. When choosing, you should consider the products of well-known brand manufacturers with mature technology, such as DYNAIR brand laboratory air compressors.
2. Compressed air quality oil-free air compressor is the first choice: the oil-free air compressor machine itself does not contain oily materials, and does not need to add any lubricating oil during work, thus greatly improving the quality of the discharged air, and supporting equipment for users. The safety is also guaranteed. Unlike oil air compressors, because the exhaust gas contains a lot of oil molecules, it will bring different degrees of corrosion to the equipments supported by the users. Therefore, the air quality guarantee is selected by the oil-free silent air compressor. necessary. After the air filter unit is configured, the air quality should meet the following international standard values:
2.1 solid particles

The filtration ratio βn = 20 (the minimum accuracy of the measurement method is usually 20% of the limit value).
(2) Ion concentration is the absolute pressure 0.1 MPa temperature 20 ° C, relative vapor pressure 0.6 concentration
2.3 Total oil (including oil droplets, suspended particles, oil vapor)
Note: The oil content of the oil with an absolute pressure of 0.1 MPa, a temperature of 20 ° C, and a relative steam pressure of 0.6.
3. The noise control industry standard stipulates that the air compressor noise of the laboratory should be controlled within 60 decibels to ensure that the experimental operators are in a relatively quiet working environment. It is recommended to select a laboratory air compressor with a noise value of about 50 decibels.
4. Safe, light and easy to operate As a pressure equipment, the air compressor must meet the requirements in terms of safety. It must pass relevant national certifications, such as ISO9001, pressure vessel certificate and international CE certification. Of course, the simpler and lighter the operation, the better.
According to authoritative investigations: In addition to the production of laboratory air compressors in Europe and the United States, such as Germany and Denmark, the export-oriented enterprise supported by the state---Shanghai Luoluo Industry and Trade Co., Ltd. has developed and produced through the introduction of advanced foreign production technology. The “DYNAIR Dasheng†DA series laboratory silent oil-free air compressor fully meets international standards and even better than foreign products in some performances. The brand products have been widely used in China's national defense science and technology, aerospace technology, national key laboratories, petrochemicals, pharmaceuticals, chromatographic analysis, university laboratories and other fields, filling the gap in China's inability to produce high-tech laboratory air compressors. Significant cost savings for domestic users. Let us be proud of having such a national brand.
Many laboratories need to purchase experimental equipment, and the procurement requirements for experimental equipment are very high. For the type of air compressor purchased by the laboratory, it must meet the characteristics of continuous and stable work, simple operation, safe use, environmental protection and energy saving. At the same time, in order to create a good working environment for the laboratory staff, the noise control requirements are very high. Therefore, an air compressor that provides a gas source specifically for experimental equipment has a large difference from a general industrial air compressor.
