Single phase screw compressor is usually a small power air compressor. The 380V 3 phase is generally suitable for large power machines. The available voltage of our single phase rotary screw compressor includes 220V, 230 volts, 240V 50hz, or 60hz. In addition, below are the powers of our 220v 230 volt 240v screw compressor: 1 hp, 2 hp, 3 hp, 4 hp, 5 hp, 5.5 hp, 7.5 hp, 10 hp, 12 hp. That is, 0.75kw, 1.5kw, 2.2kw, 3kw, 3.7kw, 5.5kw, 7.5kw, 9kw. The smallest airflow is down to 60L/min, which is about 2 cfm.
We have two kinds of 1 phase screw air compressors. One is tankless, and another is with a tank & refrigerated dryer. Here are mainly introduce the 1 phase screw compressor with dryer and tank. It has low noise (65dB). Besides, the compressed air oil content is also low. So our single phase rotary screw compressor has wide applications. You can use it for small processing plants, optical shops, hardware stores, laboratories, etc.

Why Choose Our Single Phase Rotary Screw Compressor
Our 220v 230 volts 240v screw air compressor has many advantages. It is not only compact but also low noise and power saving.
(1) Wide Applicability
We know that there is no 380v three-phase electricity supply on many occasions. These places often only have single-phase electricity, 220v, 230 volt, or 240v 1 phase. At this time, we can’t use the ordinary 3 phase air compressors anymore. Therefore, we have specially developed this single phase screw air compressor. It perfectly matches the electricity demand. It’s very suitable for small and micro enterprises and factories. Moreover, the general 3 phase screw compressor noise is relatively large. So it is especially not suitable for small processing plants and shops. But our single-phase electric air compressors are with closed enclosures. The noise is as low as 65 dB. Thus, it can solve this problem very well.
Also, our air compressors are with wheels. It is lightweight and small in size, especially suitable for mobile use. If you have high air quality requirements, you can choose an air compressor with a dryer. So our 220v 230 volts 240v screw compressor has a wider range of applications.
(2) Excellent Performance
Our single phase rotary screw compressor has passed 2000+ hours of durability testing. It adopts an integrated heavy-duty airend. Besides, the machine has six heavy-duty bearings. So the whole stability has been greatly improved. In addition, we use a new generation of oil-air separation tanks. It reduces the export oil content by 50%. The compressed air oil content is lower than 2 ppm. The air storage tank, refrigerated dryer, and filters will be highly integrated. So we can get high-quality compressed air.
Moreover, the 1 phase air compressor uses an IP67 permanent magnet motor, thus greatly improving durability. The motor uses high-performance NdFeB permanent magnets. UH magnets have a temperature resistance rating of up to 180°C. The stator coil adopts a special voltage-resistant enameled wire. Insulation properties are excellent. The service life is more than 15 years.
(3) More Energy Saving
Our 220v rotary air compressor single phase uses VFD technology. So it can completely avoid the loss of unloading power. In the state of intermittent air use, also avoid the peak value of current and torque. Therefore, the compressor can start and stop infinitely. Compared to ordinary models, VSD air compressor saves electricity by at least 20%. Besides single-phase electricity is residential electricity. Its cost is only about half of industrial electricity.
Assume that the 7.5kw 1 phase screw air compressor works 8 hours a day.
Industrial electricity = 7.5*8 = 60 CNY;
VFD energy saving=7.5*8*(1-0.2 VFD energy saving)*0.5 (civilian electricity)=24 CNY/day.
How Do Single Phase Screw Air Compressors Work
In fact, the working principle of 220v 230 volt 240v rotary screw air compressor 1 phase is similar to 3 phase. 1-phase screw compressor consists of several parts. That is, screw airend, motor, oil-air separator barrel, refrigeration system, air intake system, valves, and automatic control system, etc. The whole machine is packed in a box body.
The airend is a two-shaft volumetric rotary compression engine. The coolant is directly sprayed from the spray nozzle under the compressor casing to the toothed part of the rotor. Then it will be mixed with air. This removes the heat generated by compression. At the same time, avoid direct contact between the rotors Additionally, it reduces noise due to fast compression.
Its airend breathes according to the air inlet regulator valve. At the same time, oil is introduced into the air compression chamber. Lubricate the components of the single-phase rotary screw air compressor. Then compression chamber exhausts compressed air. The resulting mixture is discharged into the oil separator barrel. Compressed air and oil mist are separated here. Finally, the compressed air is discharged. If there is a dryer, the equipment will also cool down the compressed air and remove water. Therefore, get the air with a dew point of 3~10°C. We can use the compressed air directly.
Single Phase vs Three Phase Air Compressor
Single phase rotary screw air compressor is generally a small machine. More than 10 HP, air compressors are generally 380v three phase, not 220v 230 volt 240v 1 phase. Because 1-phase electricity is civilian electricity, the power it can withstand is limited. But industrial electricity can bear far more power.
For small businesses or shops, we recommend 220v 230 volt 240v screw air compressor 1 phase. The air consumption in these places is generally not large. Therefore, it is especially suitable for the use of small 1-phase air compressors. Moreover, its costs are less. It is also more convenient to use.
Q1: What is a single phase air compressor?
A1: It is applicable for 220V 230 volts or 240v single phase, not 380v. All piston, scroll, and screw compressors can be made into a single phase.
Q2: Can a single-phase compressor run backward?
A2: For screw air compressors, long-term reverse operation of the motor will cause the machine head to bite to death. As a result, it will lead to overload protection trips. Therefore, the twin-screw air compressor is prohibited from running backward. If it is a piston air compressor, it can work both forward and reverse.
Q3: Can the three-phase air compressor be used for 220v?
A3: Firstly, there are 220v rotary screw air compressors three phase and single phase. So if it’s 220v 1-phase, you can’t use this compressor.
Q4: Can we change the three-phase air compressor into a single phase?
Usually, it cannot be changed. The requirements for changing single-phase motors are strict. It needs to be the same from the installation position to the wheelbase. It’s hard to find single phase motors that are exactly the same. Even if it can be changed, there is still a serious problem. That is, the efficiency and power factor of three-phase and single-phase motors with the same kilowatts are different. Three-phase motors output more kinetic energy. In other words, single-phase is boring. Because it is used on an air compressor, such a long time may cause the motor to burn out!
Q5: How long is the delivery time of your single phase rotary screw compressor?
A5: The lead time of 220v 230 volt 240v screw air compressor 1phase is the same as 380v. It’s about 20 days.
Q5: What’s the price of your 240v screw compressor?
A5: This single phase rotary screw compressor has two types. One is with a refrigerant air dryer. Another is without a dryer. Of course, we also have an air compressor without a tank. So please tell us the type, power, or airflow you need. We can quote it to you soon.
