Kind note: the data above are only for our part of small screw compressor. Additionally, we are constantly improving our machines. So the above data may be subject to some changes.
Why choose our electric small rotary screw air compressor
The mini air compressor is specially designed for small discharge users. It is quiet, durable and energy efficient.
(1) Single phase available
Small rotary air compressor has low power. So single phase is completely suitable for them. Moreover, we are also the special factory of single phase screw compressor. 220V, 230V and 240V 50hz or 60hz 1-phase is available. Then our mini air compressor has wide applications.
In many occasions there is no three-phase power supply. Therefore, they can’t use the rotary air compressor before. But now we develop this 1-phase air compressor. You can use it at home, labs, shops, schools and small factories.
(2) 30% to 40% energy saving
Firstly, this mini air compressor uses PM VSD technology. So it avoids no-load energy consumption. Moreover, single-phase 220V realizes plug and play. No need transformer conversion. The single electricity cost can be saved by more than 40%. In addition, our airend meet the first-level energy efficiency standards.
(3) High quality compressed air
Our small rotary screw air compressor is with high quality filters. Besides, it adopts multi-separation technology. The outlet air oil content is less than 2ppm. There is an air receiver tank. It can also remove part of water. In addition, you can require to add a dryer, so it can get low dew point. It can significantly reduce water content of the compressed air.
(4) Our mini rotary air compressor has low noise
This small rotary air compressor is regular with silent cabinet. There are multiple noise reduction technologies. Noise value≤65dB(A). Provide you with a quiet and comfortable work space.
(5) Compact structure
This is a highly integrated air compressor system. The system integrates the airend, motor, storage tank and refrigerant air dryer. The whole machine has a simple and compact structure. It has small floor area.
How does small rotary screw air compressor work
The screw air compressor draws air into the compression airend. The two rotors change the volume in airend by meshing movements. At the same time, oil is continuously injected into the cavity. This lubricates and cools the screw. As a result, it produces a high temperature oil-air mixture. Then they pass through the oil-air separation. Finally, compressed air is separated.
Sometimes we have a requirement for the dew point of the compressed air. If the moisture is not removed, it will corrode our air-using devices. Eventually the equipment will not work properly. For this reason we have integrated dryer into small rotary air compressor.
The wet air inlet of dryer is connected to the storage tank. In addition, the dry air outlet extends out to a refrigerant dryer. The refrigerant outlet connects to the refrigeration compressor. It supplies power to the refrigerant. Then the refrigerant is exported to the evaporator. It is used to absorb heat. In addition, the refrigerated dryer has an external rotor fan. The fan cools the air flow. And carries away the heat emitted by the condenser. At the same time, the refrigerant is cooled. Ultimately, the dryer removes the moisture in the compressed air.
Q1: Can a small screw compressor run air tools?
A1: For this question, you should know the air consumption of your air tools first. Most air tools consumes about 10 to 110 cfm air. For lower size mini air compressor, it is suitable for small tools. For example, small impact wrench, air hammer and grinder can use them.
Q2: What’s the application of your small rotary air compressor?
A2: Our mini air compressed is specially developed. Many places have low cfm requirements. But these places have high requirement for air compressor noise. Besides, they are often not capable of supplying three-phase power. Our small air compressor can solve these problems well. In addition, it can also discharge high quality air.
Q3: What’s the cfm of your small air compressor?
A3: Our small air compressor is available from 1 hp to 10hp. The air flow is 2 cfm, 3.5 cfm, 7.7 cfm, 10.5 cfm, 14 cfm to 42 cfm. You can tell us the specific cfm you need.
Q4: What’s the available voltage of your small air compressor?
A4: Both single phase and three phase are available. So 220V, 230V, 240V, 380V 50hz or 60hz, etc are ok.
Q5: What’s the delivery time of your small rotary screw air compressor?
A5: If the small screw compressor is regular voltage, the time is about 20 days. If you need special voltage, the time will a little longer.
