Why 220V Single Phase Screw Air Compressor is Energy-saving
(1) Stable Working Pressure
Stable working pressure is one of the shining points of PM VSD air compressor. C'est, it can respond quickly according to the amount of air used during production. It can supply as much air as it actually needs. Outre, this small screw air compressor has a storage tank. It also plays a role in stabilizing the pressure. Cependant, there is still working pressure consumption in general compressors. The consumption is about 0.07-0.15Mpa in the middle.
(2) Different Electricity Cost
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) Different Design
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, it is relatively low energy consumption.
Single Phase Screw Air Compressor vs Three Phase
(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 a small rotary screw air compressor 3kw, it’s best to use a single phase. It is easy to move and use compared to the 3-phase power supply. For large air compressors above 3kw, it is better to choose the three phases.
(3) The starting current of the three-phase electric motor is smaller. It makes the work more stable and efficient. Outre, 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.
FAQ
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. Si 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. Si 5.5 kw screw compressor, the max pressure is 16 bar.
Q3: What’s the delivery time of your small screw air compressor?
A3: If a regular machine, the delivery time is about 15~20 days. If you need to customize it as a special requirements, the time will be about 35 jours.
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. Donc, we need a tank to balance the system’s working pressure. En outre, it also reduces the moisture content of the compressed air. The air will stay here for a while. It can deposit debris, humidité, 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.
