This small rotary screw air compressor is 220V single phase. Of course, we can also customize the 230V / 240V 1 phase. The small rotary air compressor is special for small air consumption users. It has the characteristics of micro oil, power saving, quiet and durable. Micro screw compressor has wide applications in many industries, such as spray painting, auto repair, hardware, etc.

We know that most screw air compressors are three phase. However, some users do not have access to three-phase power when using the air compressor. So they would like to have a single phase screw air compressor. The demand of the market is what we are trying to do. Our 220V 1 phase small screw air compressor has passed strict tests and many users affirmation.

① Firstly, the single phase screw air compressor is small and stable. The screw compressor airend adopts the latest screw type line. Each pair of screw rotor is a fine product with fine grinding.

② Secondly, permanent magnet synchronous VSD motor has high efficiency. When the air consumption fluctuates, the average energy saving is 35%.

③ The permanent magnet motor has IP54 protection grade. And it is not affected by environmental dust and humidity, etc. Besides, our motor uses high performance NdFeB permanent magnets. The UH magnets can withstand temperature at 180℃ without loss of magnetism. Service life is more than 15 years.

④ Secondly, this small screw air compressor is applicable to single-phase 220V household electricity.

⑤ There is no waste of no-load power consumption.

⑥ This is highly integrated compressor system. It integrates air compressor, refrigerated dryer and storage tank. The whole small rotary screw compressor is tight and safe.

⑦ Ultra-low silence, almost no vibration, easy and fast maintenance.

⑧ Our single phase screw air compressor is with intelligent controller. Operation is more humanized. Besides, it can realize parallel operation of multiple compressors.

⑨ Finally, the single phase air compressor with dryer provides high quality and clean compressed air solutions.

It achieves power saving by the following three aspects.

(1) Stable working pressure

Stable working pressure is one of the shining points of PM VSD air compressor. That is, it can respond quickly according to the amount of air used during production. It can supply as much air as it actually needs. Besides, this small screw air compressor has a storage tank. It also plays a role in stabilizing the pressure. However, there is still working pressure consumption in general compressors. The consumption is about 0.07-0.15Mpa in the middle.

(2) The cost of electricity is different between single-phase and three-phase

The common screw air compressor is three phase. This is industrial electricity. The cost is often more expensive. But our small rotary screw compressor is single phase. This is the household electricity. Its cost is often cheaper than 3-phase electricity. So this single phase screw air compressor with dryer is more energy saving.

(3) The overall design is different

PM VSD air-cooled air compressor is generally coaxial line one construction. So the transmission power is large. Transmission system consumption is small. Start and stop does not affect the service life of the motor. If the air consumption is unstable, you can choose variable speed drive air compressor. Although it is relatively expensive, but it is relatively low energy consumption.

(1) The input voltage of the single-phase air compressor is 220V. The three-phase air compressor includes 3-phase 220V and 3 phase 380V. The input voltage is different.

(2) For small rotary screw air compressor 3kw, it’s best to use single phase. It is easy to move and use compared to 3-phase power supply. For large air compressors above 3kw, it is better to choose the three phase.

(3) The starting current of the three-phase electric motor is smaller. It makes the work more stable and efficient. Besides, the torque is larger. Under the condition of three-phase electricity, should use 3 phase screw air compressor. If there is really no three-phase electricity, the only choice is to use a single phase screw air compressor.

Q1: What is the power of your single-phase screw air compressor？

A1: The available power of our single phase air compressor is 2.2KW, 3.7KW, 4.5KW, 5.5KW and 7.5KW.

Q2: What’s the max pressure of your small rotary screw compressor?

A3: Different powers, different max pressure. If 2.2 kw screw compressor, the max pressure is 10 bar. And if 3.7kw and 4.5 kw screw compressor, the max pressure is 12.5 bar. If 5.5 kw screw compressor, the max pressure is 16 bar.

Q3: What’s delivery time of your small screw air compressor?

A3: If regular machine, the delivery time is about 15~20 days. If you need customize it as special requirements, the time will be about 35 days.

Q4: What’s the tank volume of your single phase screw air compressor with dryer?

A5: The air storage tank volume of this 4.5 kw screw compressor is 130L. The role of the air storage tank is to maintain a stable output pressure of compressed air. The actual air consumption of the air compressor system will fluctuate. Therefore, we need a tank to balance the system working pressure. In addition, it also reduces the moisture content of the compressed air. The air will stay here for a while. It can deposit debris, moisture and other dirty things in the air. Thereby further improving the quality of compressed air.

Q5: What’s the noise of your 4.5 kw air compressor?

A5: This small rotary screw air compressor is quiet. And its noise is only 65dB.
