Product Description

Industrial Compressor 75kw Oil Injected Low Noise Screw Air Compressor


Screw compressors are designed for those applications that require a high volume of compressed air and/or continuous usage.
They do not require to stop for the cooling process, allowing constant air production. Silent, efficient, and reliable, Jiayi's screw
compressors grant you a more comfortable workspace, continuous usage, longer components' lifecycle, more efficiency, and
cost savings.
Screw compressors operate based on two meshing helical screw rotating in inverse order, avoiding any contact with mechanical
parts.VARIABLE SPEED SCREW COMPRESSORS
Variable speed screw compressors allow you to save up lots of power energy, compared to fixed speed ones. While traditional
compressors work at one speed (at 100%), variable speed screw compressors regulate the motor's speed to adjust to the
production's fluctuating air requirements. They are ideal for applications and production systems whose usage of compressed air
varies during the day, granting the right quantity of air needed and a saving the cost of electricity.
HIGH EFFICIENCY IN VARIABLE SPEED SCREW COMPRESSORS
The magnet permanent motor controll the energy consumption better than fixed speed compressors. This innovative technology
takes the energy savings to a new level, improving efficiency and performance. Jiayi's innovative technology guarantees
remarkable savings on energy bills, creating return on the investment in 1-2 years.

FeatureIn the workshop, air consumption is high during the day time but comparatively low in the night. In the meantime, the air
consumption in busy season is much higher than that of in low season.
92% air compressors have got serious fluctuations during operation
70% air compressors have a load between 40% to 80% while working.
Thus, there is much energy to save if we use a variable frequency compressor in stead.
1. Permanent magnet frequency conversion motor that makes the machine meets the National Level 1 energy efiiciency standard.
2. The new patent design of screw type machine equipped with 8 sets of S K F import bearing.
3. Big name brand frenquency converter / inverter, top vector frequency conversion control system.
4. Double frenquency conversion desigh makes frequency changing possible for for both motor and the fan.
5. PID air volume regulation technology for saving overall air consumption.
6. 40-200hz wide frequency option in order to meet different working conditions.
7. Stable air pressure, fluctuation within 0.1bar.
8. 0 load start, less effect on power grid.
9. A better design to seperate the low temperature and high temperature unit, so the electrical componentes have longer life span.
10. Best human manchine interface with more date and detailed function.
Smart Control Panel
The digital control panel can control versatile situation with clear display, which makes the air compressor easy to control and easy
to maintain.High Efficient Built-in Cooler
The cooler is designed for high temperature environment, it helps to keep air compressor running in an appropriate temperature.
