Advantages
| √ Simple |
| One screw rotor and 2 gate rotors which are positioned at right angle to the axis constitute 2 compressing rooms. Therefore, the screw rotor with 6 grooves compresses as many as 12 times per rotation. |
| √ Quietness |
| Without applying thrust load to the axis direction of the rotor, the force in the circumference direction rotates quietly with good balance. As a result, the load to the bearing is lightened, minimizing the generation of noise or vibration. |
| √ Durability |
| The gate rotors are rotated following the rotation of the screw rotor along its gear. The water film formed on the screw rotor’s gear and the free floating mechanism maintains the high efficiency for a long time (in case of water lubrication). |
| √ High Efficiency |
| Since the lubrication water is jetted in the compressing process, the compression is done smoothly under almost even temperature, realizing ideal, safe and highly efficient compression with slow rotation (in case of water lubrication). |

Can air compressors be used for gas compression and storage?
Yes, air compressors can be used for gas compression and storage. While air compressors are commonly used to compress and store air, they can also be utilized for compressing and storing other gases, depending on the specific application requirements. Here’s how air compressors can be used for gas compression and storage:
Gas Compression:
Air compressors can compress various gases by utilizing the same principles applied to compressing air. The compressor takes in the gas at a certain pressure, and through the compression process, it increases the pressure and reduces the volume of the gas. This compressed gas can then be used for different purposes, such as in industrial processes, gas pipelines, or storage systems.
Gas Storage:
Air compressors can also be used for gas storage by compressing the gas into storage vessels or tanks. The compressed gas is stored at high pressure within these vessels until it is needed for use. Gas storage is commonly employed in industries where a continuous and reliable supply of gas is required, such as in natural gas storage facilities or for storing compressed natural gas (CNG) used as a fuel for vehicles.
Gas Types:
While air compressors are primarily designed for compressing air, they can be adapted to handle various gases, including but not limited to:
- Nitrogen
- Oxygen
- Hydrogen
- Carbon dioxide
- Natural gas
- Refrigerant gases
It’s important to note that when using air compressors for gas compression and storage, certain considerations must be taken into account. These include compatibility of the compressor materials with the specific gas being compressed, ensuring proper sealing to prevent gas leaks, and adhering to safety regulations and guidelines for handling and storing compressed gases.
By leveraging the capabilities of air compressors, it is possible to compress and store gases efficiently, providing a reliable supply for various industrial, commercial, and residential applications.

How do you troubleshoot common air compressor problems?
Troubleshooting common air compressor problems can help identify and resolve issues that may affect the performance and functionality of the compressor. Here are some steps to troubleshoot common air compressor problems:
1. No Power:
- Check the power source and ensure the compressor is properly plugged in.
- Inspect the circuit breaker or fuse box to ensure it hasn’t tripped or blown.
- Verify that the compressor’s power switch or control panel is turned on.
2. Low Air Pressure:
- Check the air pressure gauge on the compressor. If the pressure is below the desired level, the compressor might not be building up enough pressure.
- Inspect for air leaks in the system. Leaks can cause a drop in pressure. Listen for hissing sounds or use a soapy water solution to identify the location of leaks.
- Ensure the compressor’s intake filter is clean and not clogged, as this can restrict airflow and reduce pressure.
3. Excessive Noise or Vibration:
- Inspect the compressor’s mounting and foundation to ensure it is secure and stable. Loose mounts can cause excessive noise and vibration.
- Check for loose or damaged components, such as belts, pulleys, or motor mounts. Tighten or replace as necessary.
- Verify that the compressor’s cooling system, such as the fan or fins, is clean and free from obstructions. Overheating can lead to increased noise and vibration.
4. Air Leaks:
- Inspect all connections, valves, fittings, and hoses for leaks. Tighten or replace any loose or damaged components.
- Apply a soapy water solution to suspected areas and look for bubbles. Bubbles indicate air leaks.
- Consider using thread sealant or Teflon tape on threaded connections to ensure a proper seal.
5. Excessive Moisture in Compressed Air:
- Check the compressor’s drain valve and ensure it is functioning properly. Open the valve to release any accumulated moisture.
- Inspect and clean the compressor’s moisture separator or air dryer, if equipped.
- Consider installing additional filtration or drying equipment to remove moisture from the compressed air system.
6. Motor Overheating:
- Ensure the compressor’s cooling system is clean and unobstructed.
- Check the motor’s air intake vents and clean any dust or debris that may be blocking airflow.
- Verify that the compressor is not being operated in an excessively hot environment.
- Check the motor’s lubrication levels and ensure they are within the manufacturer’s recommended range.
- Consider using a thermal overload protector to prevent the motor from overheating.
If troubleshooting these common problems does not resolve the issue, it may be necessary to consult the manufacturer’s manual or seek assistance from a qualified technician. Regular maintenance, such as cleaning, lubrication, and inspection, can also help prevent common problems and ensure the optimal performance of the air compressor.

How do you choose the right size of air compressor for your needs?
Choosing the right size of air compressor is essential to ensure optimal performance and efficiency for your specific needs. Here are some factors to consider when selecting the appropriate size:
1. Air Demand: Determine the air demand requirements of your applications. Calculate the total CFM (Cubic Feet per Minute) needed by considering the air consumption of all the pneumatic tools and equipment that will be operated simultaneously. Choose an air compressor with a CFM rating that meets or exceeds this total demand.
2. Pressure Requirements: Consider the required operating pressure for your applications. Check the PSI (Pounds per Square Inch) rating of the tools and equipment you will be using. Ensure that the air compressor you choose can deliver the necessary pressure consistently.
3. Duty Cycle: Evaluate the duty cycle of the air compressor. The duty cycle represents the percentage of time the compressor can operate within a given time period without overheating or experiencing performance issues. If you require continuous or heavy-duty operation, choose a compressor with a higher duty cycle.
4. Power Source: Determine the available power source at your location. Air compressors can be powered by electricity or gasoline engines. Ensure that the chosen compressor matches the available power supply and consider factors such as voltage, phase, and fuel requirements.
5. Portability: Assess the portability requirements of your applications. If you need to move the air compressor frequently or use it in different locations, consider a portable or wheeled compressor that is easy to transport.
6. Space and Noise Constraints: Consider the available space for installation and the noise restrictions in your working environment. Choose an air compressor that fits within the allocated space and meets any noise regulations or requirements.
7. Future Expansion: Anticipate any potential future expansions or increases in air demand. If you expect your air demand to grow over time, it may be wise to choose a slightly larger compressor to accommodate future needs and avoid the need for premature replacement.
8. Budget: Consider your budgetary constraints. Compare the prices of different air compressor models while ensuring that the chosen compressor meets your specific requirements. Keep in mind that investing in a higher-quality compressor may result in better performance, durability, and long-term cost savings.
By considering these factors and evaluating your specific needs, you can choose the right size of air compressor that will meet your air demand, pressure requirements, and operational preferences, ultimately ensuring efficient and reliable performance.
