Product Description VARIABLE SPEED SCREW AIR COMPRESSOR 7.5KW 15KW 22KW 37KW WITH PERMANENT MAGNET MOTORProduct DescriptionScrew 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 screwcompressors grant you a more comfortable workspace, continuous usage, longer components' lifecycle, more efficiency, andcost savings.Screw compressors operate based on two meshing helical screw rotating in inverse order, avoiding any contact with mechanicalparts.VARIABLE SPEED SCREW COMPRESSORSVariable speed screw compressors allow you to save up lots of power energy, compared to fixed speed ones. While traditionalcompressors work at one speed (at 100%), variable speed screw compressors regulate the motor's speed to adjust to theproduction's fluctuating air requirements. They are ideal for applications and production systems whose usage of compressed airvaries during the day, granting the right quantity of air needed and a saving the cost of electricity. HIGH EFFICIENCY IN VARIABLE SPEED SCREW COMPRESSORSThe magnet permanent motor controll the energy consumption better than fixed speed compressors. This innovative technologytakes the energy savings to a new level, improving efficiency and performance. Jiayi's innovative technology guaranteesremarkable savings on energy bills, creating return on the investment in 1-2 years.

In the meantime, the airconsumption in busy season is much higher than that of in low season.92% air compressors have got serious fluctuations during operation70% 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 PanelThe digital control panel can control versatile situation with clear display, which makes the air compressor easy to control and easyto maintain.High Efficient Built-in CoolerThe cooler is designed for high temperature environment, it helps to keep air compressor running in an appropriate temperature.Detailed PhotosFactory detailsPackaging & Shipping
