350 cfm air compressor has sufficient air volume. And its power is 75 hp 55kw. This screw compressor is power frequency type. That is, it’s fixed speed drive rotary screw air compressor. Of course, we also produce the 75hp VSD air compressor. There are several pressures for your choice. That is, 7 bar, 8bar, 10 bar and 12bar. We are industrial screw compressor manufacturer. So our factory can strong customization ability. The regular voltage of 350 cfm compressor is 380V 50HZ 3phase. But we also provide special voltages, such as 220V, 240V, 440V, 600V and 60HZ.

(1) Stable compressor quality

The airend of the screw compressor is Hanbell brand. It uses good materials. The rotor bearing is the SKF brand in Sweden. It has a long service life — up to 100,000 hours. The compressor airend is compact in size and low in speed. Volumetric efficiency is high. In addition, the protection level of the air compressor motor is IP54. The insulation class is F class. So waterproof and dust-proof performance is good. Besides, the motor uses high-grade electromagnetic steel. It can withstand the temperature of 180°C. Therefore, our rotary screw air compressor has low failure rate.

(2) Intelligent air compressor control system

This 350 cfm air compressor adopts microcomputer control. Real-time online monitoring: pressure, power and temperature fluctuations. The operating status & data and fault warning are clear at a glance. Moreover, it can prompt the life of compressor wearing parts. So maintenance is easy.

(3) Structure and transmission advantages

Due to the enlarged oil-air system, the pressure loss of the air compressor pipeline is small. This 350 cfm compressor adopts elastic coupling direct drive. Avoid the disadvantages of belt drive. That is, it is easy to generate slip, and the transmission efficiency is low. The efficiency of belt drive air compressor is only about 85%. Moreover, the elastic coupling can eliminate the misalignment. So reduce starting shock load. Finally, extend the service life of airend and bearings.

(4) Advantages of oil-air separation system

This 350 cfm air compressor has good oil-air separation effect. The oil content of the outlet air is lower than 3PPM. Moreover, our oil separator element has a long service life. It’s up to 8000 hours. The characteristic is three-stage separation. That is, vortex centrifugation, gravity and filtration separation.

VSD air compressors are not absolutely power-saving. Some factories have no fluctuations in the air-use end. At this time, rotary screw compressors run at full capacity all the time. Therefore, the inverter cannot play the role of adjusting the speed and reducing energy consumption. Conversely, the inverter also consumes power. So whether the VSD air compressor can save electricity depends on how the customer uses and configures it.

The air consumption of these plants is very stable. If you can calculate the actual air consumption accurately, it is also a good choice to buy a fixed speed screw compressor. Of course, most factories have very unstable air consumption. The ups and downs fluctuate greatly. So most still choose variable speed drive air compressor. Of course, fixed speed 350 cfm air compressor is cheaper.

Q1: Can I directly add a inverter to the fixed speed air compressor by myself?

A1: No. It can’t achieve the expected effect after installing the frequency converter.

Q2: How much power motor does a 10m³/min air compressor need?

A2: For our screw air compressor, you can choose the 75 hp air compressor. When the air pressure is 7bar, the air capacity can reach 10m³/min.

Q3: What kind of lubricant oil do you use for your 350 cfm screw air compressor?

A3: Our 75hp air compressor uses the Shell brand S46 lubricant oil.

Q4: What do I do if forget the air compressor password?

A4: This is not a big problem. Please contact us for the password.

Q5: Do I also need the compressed air dryer for the 75 hp screw compressor?

A5: This mainly bases on your industry application. If your industry has requirement for the water content, the compressor air dryer is necessary. Of course, most industries generally require at least a refrigerant air dryer.

Q6: What’s the production time for your 350 cfm air compressor?

Q7: If you only need the regular 350 cfm compressor, the delivery time is about 20 days.
