Why Choose Lingyu 5.5kw 7.5hp Screw Air Compressor
(1) Highly Energy Efficient
The air demand fluctuates up and down for various operating conditions. As a result, there are significant differences in the air requirements for the compressor. Many applications require a stable air supply. Therefore, variable-frequency air compressors can provide significant energy savings.
The production of compressed air can account for up to 40% of all power costs in a plant. In almost every plant, the amount of air used varies with varies from time to time. It has its high and low peak hours. Our PM VSD 7.5 hp screw compressor can supply air exactly as the air consumption volume. This not only saves a lot of energy but also protects the environment.
Single-phase 220V is suitable for a wide range of applications. Because of frequency conversion technology, the starting current is low. Residential electricity is also available. So its cost is far less than industrial electricity. Single phase screw compressor for sale is more energy efficient than 3 phase air compressor.
(2) Stable And Durable Quality
High-efficiency compressor airend adopts six heavy-duty bearings. Due to the moist taper connection, it controls the vibration frequency within 1mm/s. In addition, our 5.5 kw compressor uses” IE4″ permanent magnet inverter motor. It is high-efficiency, energy-saving, and power-saving. Besides, it uses heavy-duty inverter. So it has reliable performance. And it is easy to operate.
Our 7.5 hp screw compressor is equipped with high-quality parts. Because of the intelligent air inlet valve, convenient to control the air inlet effect. With an external oil separator and oil filter, it’s convenient for customers to maintain and repair. The sing a large rotor fan, heat dissipation is fast. And screw type air compressor has low noise. In addition, the safety valve has a sensitive and reliable action. Its opening pressure is PN*1.1.
(3) High Quality Clean Compressed Air
Our 5.5 kw compressor comes with a multi-stage separation technology. So it can ensure the air content is under 2ppm. Moreover, the screw compressor is with a refrigerated dryer. It can control the air moisture at a very low level.
(4) Simple Structure And Stable Performance
The structure of the 7.5 hp screw compressor is relatively simple. The number of parts required is small. In addition, the size of the single phase screw compressor for sale is relatively small. The weight is also small. The actual floor space is very small. Besides, it has better power balance performance.
Maintenance of 5.5 kw 7.5 hp Single Phase Air Screw Compressor
- Before replacing the parts, it is necessary to disconnect the power and unload the air tank pressure and then operate.
- Regularly drain water out of the air storage tank.
- Regularly clean the heat exchanger and fan of 7.5 hp screw compressor .
- If the 5.5 kw compressor is idle for a long time, need to replace the lubricant before operation.
- In addition, regularly check the internal air and oil pipes for looseness.
- Keep the automatic drain of single phase screw compressor for sale at all times.
