How to choose an air compressor for laboratory or scientific research?

Author: Bella Zhang

High-precision instruments used in laboratories or scientific research places have special requirements for the selection and use of air compressors.

In addition to providing aerodynamic drive for the operation execution unit, it is also necessary to provide the laboratory equipment with the compressed air required for the experiment, so the overall requirements for the air compressor are also very high.

01 Laboratory or research air compressor requirements

If the compressed air of the oil-injected air compressor is improperly filtered, the oil and gas will affect the valves, nozzles, pollute the air or affect the experimental results, so the laboratory generally uses oil-free air compressors for analysis, testing and quality control.

Compressed air quality

?Q What are the requirements for the drying degree of compressed air?

?A As the gas used for experimental analysis, it needs to be equipped with a refrigerated dryer or even a suction dryer to completely remove the liquid water in the air, and reduce the pressure dew point of the output air to about 3 °C. Some laboratory equipment even requires the pressure dew point to drop to -40 ℃ or -60℃, to achieve the humidity level 2 to 1 specified in ISO8573-1.

Q Control of output air particulate matter?

?A Laboratory analysis and testing instruments have high requirements for particulate matter in the air, generally reaching the level 2 or 1 of solid particulate matter specified in ISO8573-1.

"CLASS 0" is oil-free compressed air, and the measurement is carried out under the "reference condition" of 20°C, and the actual working conditions are far more severe than this.

?The filter can only filter oil droplets; oil mist and oil and gas need activated carbon adsorbent to remove, but the life is very short. "CLASS 0" oil-free compressed air can only be obtained from "oil-free compressors".

Running sound

?For the professional experimental equipment that laboratory personnel have faced for a long time, a quiet environment is particularly important.

?According to the "Design Specifications for Noise Control of Industrial Enterprises" GB/J87-1985, the noise of the central laboratory shall not exceed 60 DbA.

Operational stability

?The stability and reliability of the air compressor provides a guarantee for researchers to focus on research.

?At the pressure of 0.65~0.8Mpa, it provides continuous and reliable compressed air for laboratory data analysis and measurement results, and at the same time, the maintenance of laboratory air compressors is also simple and easy.

Size

?The laboratory space is very limited, and the air compressor, air storage tank, and refrigeration dryer are highly integrated and occupy a small space.

SEN series oil-free scroll air compressor

The worry-free scroll series innovatively designed by SEN is widely used in any medical, laboratory, water treatment, biopharmaceutical, environmental protection, marine, textile, petrochemical, precision electronics, instrumentation, spraying, tobacco, nitrogen production, optics, national defense scientific research, etc. Areas where clean compressed air is required.

Oil-free clean

?Comply with the world's highest level of oil-free compressor air standards to ensure the safety of user production.

Super sound-off

?There is no contact between the dynamic and static scrolls, the vibration of the body is small, and the running sound is extremely low.

Low maintenance cost

? High-quality parts, long service life, low replacement frequency of consumables, and low maintenance costs.
