The low-pressure air compressor can be configured according to the user’s air pressure, using the least energy to meet your technological process, saving a lot of energy, and the manufacturing cost of your products will be considerably improved, and energy-saving and emission reduction will be realized. Commonly used air compressors generally have a pressure of 0.7mpa-0.8mpa. If the air pressure of your equipment is only 0.2-0.5Mpa, choosing a conventional 0.7Mpa air compressor will cause a huge waste of electricity, so choose Sollant low-pressure screw air compressor can save electricity by 20-50%. It is suitable for cement, chemical fiber, textile, ceramics, glass, surveying and surveying, exploration, and other industries that require large volume and low-pressure gas. In large factories, it is favored by users due to its stable performance, low failure rate, and easy maintenance.
According to the user’s working pressure, the internal compression ratio is automatically adjusted, and the best specific power can be maintained within the exhaust pressure range of 0.2~0.5Mpa. The forced lubrication of the oil pump is used to ensure sufficient fuel injection and the best air-air mixing ratio under extremely low exhaust pressure.

Knowledge of Low Pressure Air Compressor
Air compressors have become indispensable machinery in most factories. Whether used as a pneumatic mechanical energy source, air blowing and auxiliary use of other machinery have played a pivotal role. Different machinery uses air compressors with different pressures. Due to the difference in pressure in factory applications, there are two types of screw air compressors: high pressure and low pressure.
What is a low-pressure compressor?
Air compressors with exhaust pressure (use pressure) less than 0.8Mpa are called low-pressure machines. According to market demand, 8 Bar screw air compressors are in huge demand and have the most extensive production. Generally, we call air compressors less than 8 Bar as low pressure air compressors(low psi air compressors).
Examples and Applications:
In recent years, some high volume low-pressure screw air compressors have been designed according to the pressure of users. This is a relatively energy-saving product and has been slowly accepted by many customers.
The low-pressure air compressor is designed for cement, chemical fiber, textile, ceramics, printing and dyeing, glass, petrochemical, surveying and surveying and other industries with large volume and low pressure (0.2-0.5Mpa) gas industrial.
The pressure of the texturing machine used for blowing in the glass bottle industry and the textile industry is 0.25~0.3Mpa. Generally, it is recommended to use an air compressor with a pressure of 0.3~0.35Mpa.
Cement transportation: molding machinery in the foam industry. The yarn pressure in the textile industry is between 0.40 and 0.45 Mpa. Generally, air compressors with a pressure between 0.5 and 0.55 Mpa are used. The power gas with a pressure between 0.50 and 0.6 Mpa is generally recommended. Choose 0.70~0.75Mpa pressure
Low Pressure Screw Air Compressor Buying Guide
Atmospheric pressure 8 bar screw air compressor production technology is mature, and the production line is large. In general, whether it is a distributor or a manufacturer in the market, the recommended atmospheric air compressor is 8 bar or 10 bar, which is enough for most of our equipment. To use, there are many types of equipment that require non-normal pressure air compressors. For example, the laser cutting machine requires 16 bar, 20 bar, or even 30 bar.
The blowing industry may require tens of bar or even hundreds of bar of pressure. These can be used by custom The pressure is sufficient, but some customers have overlooked a problem. What if the required pressure is less than 8 bar? At this time, the dealer will say that 8 bar is enough, a bigger one is enough, and a smaller one is not good, but is this really the case?
As far as our common textile industry is concerned, the air-jet knitting machine needs 4-5 bar of pressure is enough, you may think 8 bar is OK, anyway, the machine is not broken, but have you considered a problem, the air compressor is extremely wasteful Electric equipment, its electricity consumption can account for 20% of the total electricity of the factory, which is very expensive. If you choose the right air compressor equipment, it will greatly save electricity, then you will have questions.
Buy 8 bar and buy What’s the difference between low voltage, isn’t it all such a large amount of electricity? Let us take 37kw8bar and 37kw5bar air compressors as examples to discuss the issue of electricity usage. The actual gas output of the 37kw8bar air compressor is 6.28 cubic meters per minute, the shaft power used is 39.4kw, and the specific power is 6.26kw/m3/min, while the gas output of the 37kw5bar equipment is 7.52 cubic meters per minute, and the shaft power used is 37.3kw. The specific power is 4.96kw/m3/min, 37kw 5bar air compressor saves electricity per hour than 8bar air compressor is (6.26-4.96)*7.52 *1h= 9.776 kw.h, taking the factory to work 8 per day Hours, 300 days of operation per year, the electricity saved in a year is: 9.776*8*300=23462.4kw, which is 23462.4 kilowatt-hours of electricity, according to China’s industrial electricity 1 yuan per kilowatt-hour (different prices in different regions), then one year The cost of an air compressor can be saved.
If the air compressor produced by our company can be used for 8 to 10 years, only the air compressor can save more than one hundred and two hundred thousand. For an air compressor, this cost-saving is considerable.
When your air pressure is 0.2-0.5Mpa, choosing a conventional 0.7Mpa air compressor will cause a huge waste of electricity. Choosing a medium and low pressure air compressor can greatly increase the compressed air production under the same motor power. Correspondingly, you can save power by 20-50%.
If you buy a 0.7Mpa machine, and the actual use pressure is 0.3Mpa, its working process is usually like this: the screw host first compresses the air to 0.7Mpa, and then reduces the pressure to 0.3Mpa through the pressure reducing valve. In other words, if you use a pressure of 0.3Mpa, what you bear is power consumption of 0.7Mpa.
