We produce small screw air compressor. This 5.5 kw compressor is air compressor with tank and refrigerated dryer. And 7.5 hp screw compressor can be 3 phase and single phase. Reliable single phase screw compressor for sale. Our 5.5kw screw air compressor has many advantages. Firstly, the 7.5hp air compressor is quiet. Its noise level is 65±3dB(A). Secondly, it has simple structure and good stability, etc. Besides, it can generate high quality clean compressed air. Due to refrigerated air dryer, it can remove moisture effectively.

(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 moist taper connection, it controls the vibration frequency within 1mm/s. In addition, our 5.5 kw compressor uses”IE4″ permanent magnet inverter motor. High efficiency, energy saving and power saving. Besides, it uses heavy duty inverter. So it has reliable performance. And easy to operate.

Our 7.5 hp screw compressor is equipped with high quality parts. Because of intelligent air inlet valve, convenient to control air inlet effect. With external oil separator and oil filter,it’s convenient for customers to maintain and repair. Using large rotor fan, heat dissipation is fast. And 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 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 7.5 hp screw compressor is relatively simple. The number of parts required is small. In addition, the size of 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.

Compressed air has wide applications. It has become one of the major industrial power sources. And we usually use refrigerated dryer for drying the air. In compressed air, there is mainly moisture, dust and oil. The main function of refrigerant dryer is to remove the moisture. Many companies do not use refrigerant dryers in order to save costs.

As a result, a large amount of water in the air entering the air-usage end. This in turn leads to equipment failure and damage. At the same time, the pipeline rusts and corrodes. Finally, the product defect rate increases. So it will greatly increase production costs. Fortunately, this 7.5 hp single phase screw compressor for sale has a refrigerant dryer.

How does the refrigeration air dryer work?
The refrigerant dryer cools down the temperature by cooling the refrigerant. This causes the water vapor in the compressed air to condense into liquid droplets. Ultimately, it can achieve the purpose of reducing the moisture content. The condensed liquid droplets are discharged from the 5.5 kw compressor through an automatic drainage system.

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.

Q1: What’s this air compressor is three phase or single phase?

A1: The voltage and frequency of this 7.5 hp screw compressor is custom. Both 3 phase and single phase are avaiable. Besides 220V and 380V, we can also do 240V, 415V, 440V and 460V.

Q2: What’s the tank volume of your 5.5 kw screw air compressor?

A2: The air receiver tank has small volume. The volume is 130 L.

Q3: Is your 7.5 hp screw air compressor noisy?

A3: The noise of this single phase screw compressor for sale is low. It’s only 65dB.

Q4: What’s your lead time of single phase screw compressor for sale?

A4: The usual delivery time of our 5.5 kw compressor is about 20 days. If customize special voltages, the production time will be a bit longer.
