Features of This 11kw 15 hp Rotary Screw Air Compressor
(1) Stable Discharge Air Pressure
This industrial rotary screw air compressor has VFD. Therefore, it has the characteristics of step-less speed regulation. Through the PID adjustment inside the inverter, it can quickly adjust pressure. It is different from the upper and lower limit switch control of power frequency operation. Therefore, it can greatly improve the air pressure stability. Moreover, our 11kw 15 hp screw compressor price is cheap.
(2) VSD Industrial Air Compressor More Energy-saving
Different industrial screw compressor manufacturers have different energy-saving operation modes. But all the VFD frequency converter adjusts the motor speed in real-time according to the actual air consumption. Therefore, when the air consumption is low, the air compressor can automatically sleep. This greatly reduces energy losses.
During the life cycle of an air compressor, the total cost consists of 4 parts. That is procurement, installation, maintenance, and energy consumption. Among them, the cost of energy consumption accounts for about 70% of the total cost. The initial investment cost of purchasing a screw compressor is only about 12%. Frequency conversion technology can significantly reduce air compressor energy consumption. The average energy saving can reach 30%.
(3) Use High Quality Spare Parts
Firstly, this 11kw 15 hp screw air compressor uses a high-efficiency permanent magnet motor. It has a strong magnetic field, and it does not lose magnetism at high temperatures. Therefore, the working life is long. Besides, PM motors do not have motor bearings. It clears the failure point. Transmission efficiency reaches up to 100%. So it can achieve low noise and low energy consumption. The maintenance is low.
Secondly, the airend of our industrial screw compressor is a reliable Hanbell brand. It adopts a large rotor and low-speed design. Moreover, the use of SKF bearings is imported from Sweden. So low noise and low energy consumption.
Thirdly, use the original oil and air separator. The precise element can effectively reduce the oil content of the exhaust air.
Finally, it uses a good high-pressure cooling system, so it has high heat dissipation efficiency. It can work continuously no matter in high-temperature and high-humidity environments. Thus, it improves the stability of the industrial rotary screw air compressor.

Industrial Air Compressor Troubleshooting
The 11kw 15 hp screw compressor has the characteristics of a simple structure, small size, and lightweight. The exhaust is continuous and the vibration is small. It has a few wearing parts, easy to use and maintain. Moreover, it has good stability, reliable operation, and long service life. Of course, there will be some problems during the operation. Do timely repair and maintenance.
(1) Exhaust Temperature of The Compressor Airend is High
Screw air compressors often operate at high temperatures. This will seriously affect the airflow and service life. When the temperature rise is too high, a high-temperature shutdown failure will occur. Common reasons are as follows:
- Firstly, the temperature sensor may be faulty. This will cause the PLC to falsely report that the temperature is too high. Eventually causing downtime.
- Secondly, the amount of lubricating oil is insufficient. The oil cooler is dirty and clogged. So it will cause the temperature to be too high.
- Thirdly, the temperature control valve may have a problem. If the temperature control valve is damaged, a large amount of high-temperature oil will not pass through the cooler. Instead, loop directly into the compressor airend. As a result, the temperature of the airend is high.
- Fourth, the oil filter is faulty. It is easy to clog after a period of use. After the blockage, the oil return is not smooth. Thus, the temperature of the airend is high.
- Finally, the cooling fan may fail. The air cooler is blocked, and the air exhaust resistance is too high. Poor heat dissipation causes high temperatures. So we should clean the external dust and internal oil of the cooler.
(2) Too Low Output Exhaust Pressure
- Actual air consumption is greater than the rated airflow of the industrial screw compressor. For 11kw 15 hp screw compressor, its air capacity is 60 cfm @7bar. We should check the connection equipment and pipe network. If there is a leakage, repair it in time. If there is no leakage, you need to add the air compressor.
- The set value of unloading pressure is too low. Correctly set this value.
- The air filter element is clogged. Therefore, the intake air volume of the compressor unit is insufficient. Also, the exhaust pressure is too low. We need to check the air filter condition. Replace if necessary.
- Solenoid valve may have failure. Replace it to avoid leakage.
- Intake valve action is not sensitive. Not fully opened. So need to overhaul and check the condition of the control system.
- The oil separator is blocked. Replace the oil separator filter element.
- The safety valve leaks. We need to recalibrate or replace the valve.
(3) Frequent Unloading
The pressure difference between loading and unloading of the pressure controller is too small. Reset the loading and unloading pressure value.
The actual air consumption during production is unstable. Sometimes large and sometimes small or discontinuous. We can add an air receiver tank after the compressor.
When the compressor is unloading, the minimum pressure valve is not closed in time or not tightly. Overhaul the minimum pressure valve. Replace it if necessary.
The loading control solenoid valve is faulty. It may be affected by oil and water vapor. So it causes insensitivity or coil burnout. Check and replace if necessary.
The pressure sensor of the 15 hp screw air compressor is faulty or damaged. You should repair or replace it.
