The state clearly classifies energy efficiency levels limit value. The 2 class energy efficiency products can save 10%~15% of the power than 3 class energy efficiency products.and the 1 class energy efficiency products can save 10%~15% of the power than 2 class energy efficiency products. energy-saving effect is remarkable .
Energy -saving principle :
- Curve 12 ‘3’ is an isothermal compression process, it form the area of 613 ‘4 with Y-axis which is the indicated work of isothermal compression
- Curve 123” is the 1 stage compression process, it form the area 613 ”4 with Y-axis which is the indicator work of the 1 stage compression.
- Curve 12, 22 ‘and 2′ 3 are the 2 stage compression process, and the sum of the area 6125 and the area 52 ’34 (6122’ 34) with Y-axis which is the indicator work of the 2 stage compression.
- It can be seen from the diagram that the isothermal compression process 613 ‘4 area (indicating work) is the smallest, but it is impossible to achieve isothermal compression in the air compressors’ actual compression.
The 1 stage compression has the bigger area of power 13 ‘3 than isothermal compression, while the 2 stage compression saves 22″ 33 “area of power.
Features description:
- Oil injected screw air compressor can achieve the usual power system exhaust pressure by only Single stage compression. But from the view of energy consumption point, the use of 2 stage of compression can effectively reduce energy consumption.
- So, ZheJiang Great air compressor co., LTD. has introduced 2 stage compression of energy efficiency screw air compressor. The 2 stage compressed-jet screw air compressor has more capacity of 12% to 18% than the CHINAMFG compressed injection screw air compressor with the equivalent power. In other words, with the same amount of compressed air, the 2 stage compression can save an average of 15% of power compared with 1 stage compression
- 2 stage compression of oil injected screw machine has the unique design of the air end, it will combined the1 stage compression rotor and 2 stage compression rotor within a chassis, make each rotor can get optimal linear velocity by the gear directly rotating respectively, so the compression efficiency is higher.
2 stage compression air compressor, take the built-in spray curtain of cooling, cooling effect is good, greatly reduces the temperature of compressed air, realize the nearly isothermal compression, and can reduce the pressure loss of between 1 class ~ 2 class, lower compression ratio and improve the compression efficiency
- After 1 stage compression, coolant through multiple jet hole on the body, form the mist jet shade, to cool the hot 1 stage compressed air, greatly reduces the compressed air temperature before entering the 2 stage compression, which is near to isothermal compression process, save the energy compression effect.
- Even without inter-stage cooling, 2 stage compression is more efficient than CHINAMFG compression. This is because the volume of air becomes smaller after the 1 stage compression, so the 2nd stage compression can use a smaller diameter of the rotor, and the leakage rate of the unit volume is small.
- Reduce internal leakage: use 2 stage compression, reduce the compression ratio of each compression, reduce the leakage from the high pressure side to the low pressure side per class, and improve the volume efficiency.
- Noise reduction: the compression ratio of each compression is reduced by taking 2 stage compression, which greatly reduces the noise, especially the unloading noise
- 2 stage compression unit, except for screw air end, the other system and structure arrangement of the unit is basically the same as the CHINAMFG compression, which is convenient for the maintenance and usage to the user.
- For users who need large air consumption and continuously use, should take priority to use of a 2 stage compressed 1 class energy efficiency air compressor

What are the key components of an air compressor system?
An air compressor system consists of several key components that work together to generate and deliver compressed air. Here are the essential components:
1. Compressor Pump: The compressor pump is the heart of the air compressor system. It draws in ambient air and compresses it to a higher pressure. The pump can be reciprocating (piston-driven) or rotary (screw, vane, or scroll-driven) based on the compressor type.
2. Electric Motor or Engine: The electric motor or engine is responsible for driving the compressor pump. It provides the power necessary to operate the pump and compress the air. The motor or engine’s size and power rating depend on the compressor’s capacity and intended application.
3. Air Intake: The air intake is the opening or inlet through which ambient air enters the compressor system. It is equipped with filters to remove dust, debris, and contaminants from the incoming air, ensuring clean air supply and protecting the compressor components.
4. Compression Chamber: The compression chamber is where the actual compression of air takes place. In reciprocating compressors, it consists of cylinders, pistons, valves, and connecting rods. In rotary compressors, it comprises intermeshing screws, vanes, or scrolls that compress the air as they rotate.
5. Receiver Tank: The receiver tank, also known as an air tank, is a storage vessel that holds the compressed air. It acts as a buffer, allowing for a steady supply of compressed air during peak demand periods and reducing pressure fluctuations. The tank also helps separate moisture from the compressed air, allowing it to condense and be drained out.
6. Pressure Relief Valve: The pressure relief valve is a safety device that protects the compressor system from over-pressurization. It automatically releases excess pressure if it exceeds a predetermined limit, preventing damage to the system and ensuring safe operation.
7. Pressure Switch: The pressure switch is an electrical component that controls the operation of the compressor motor. It monitors the pressure in the system and automatically starts or stops the motor based on pre-set pressure levels. This helps maintain the desired pressure range in the receiver tank.
8. Regulator: The regulator is a device used to control and adjust the output pressure of the compressed air. It allows users to set the desired pressure level for specific applications, ensuring a consistent and safe supply of compressed air.
9. Air Outlet and Distribution System: The air outlet is the point where the compressed air is delivered from the compressor system. It is connected to a distribution system comprising pipes, hoses, fittings, and valves that carry the compressed air to the desired application points or tools.

What role do air dryers play in compressed air systems?
Air dryers play a crucial role in compressed air systems by removing moisture and contaminants from the compressed air. Compressed air, when generated, contains water vapor from the ambient air, which can condense and cause issues in the system and end-use applications. Here’s an overview of the role air dryers play in compressed air systems:
1. Moisture Removal:
Air dryers are primarily responsible for removing moisture from the compressed air. Moisture in compressed air can lead to problems such as corrosion in the system, damage to pneumatic tools and equipment, and compromised product quality in manufacturing processes. Air dryers utilize various techniques, such as refrigeration, adsorption, or membrane separation, to reduce the dew point of the compressed air and eliminate moisture.
2. Contaminant Removal:

1. Variable Speed Drive (VSD) Compressors:
VSD compressors are designed to adjust the motor speed according to the compressed air demand. By varying the motor speed, these compressors can match the output to the actual air requirement, resulting in energy savings. VSD compressors are particularly effective in applications with varying air demands, as they can operate at lower speeds during periods of lower demand, reducing energy consumption.
2. Energy-Efficient Motors:
The use of energy-efficient motors in air compressors can contribute to energy savings. High-efficiency motors, such as those with premium efficiency ratings, are designed to minimize energy losses and operate more efficiently than standard motors. By using energy-efficient motors, air compressors can reduce energy consumption and achieve higher overall system efficiency.
3. Heat Recovery Systems:
Air compressors generate a significant amount of heat during operation. Heat recovery systems capture and utilize this wasted heat for other purposes, such as space heating, water heating, or preheating process air or water. By recovering and utilizing the heat, air compressors can provide additional energy savings and improve overall system efficiency.
4. Air Receiver Tanks:
Air receiver tanks are used to store compressed air and provide a buffer during periods of fluctuating demand. By using appropriately sized air receiver tanks, the compressed air system can operate more efficiently. The tanks help reduce the number of starts and stops of the air compressor, allowing it to run at full load for longer periods, which is more energy-efficient than frequent cycling.
5. System Control and Automation:
Implementing advanced control and automation systems can optimize the operation of air compressors. These systems monitor and adjust the compressed air system based on demand, ensuring that only the required amount of air is produced. By maintaining optimal system pressure, minimizing leaks, and reducing unnecessary air production, control and automation systems help achieve energy savings.
6. Leak Detection and Repair:

Are there differences between single-stage and two-stage air compressors?
Yes, there are differences between single-stage and two-stage air compressors. Here’s an in-depth explanation of their distinctions:
Compression Stages:
The primary difference between single-stage and two-stage air compressors lies in the number of compression stages they have. A single-stage compressor has only one compression stage, while a two-stage compressor has two sequential compression stages.
Compression Process:
In a single-stage compressor, the entire compression process occurs in a single cylinder. The air is drawn into the cylinder, compressed in a single stroke, and then discharged. On the other hand, a two-stage compressor utilizes two cylinders or chambers. In the first stage, air is compressed to an intermediate pressure in the first cylinder. Then, the partially compressed air is sent to the second cylinder where it undergoes further compression to reach the desired final pressure.
Pressure Output:
The number of compression stages directly affects the pressure output of the air compressor. Single-stage compressors typically provide lower maximum pressure levels compared to two-stage compressors. Single-stage compressors are suitable for applications that require moderate to low air pressure, while two-stage compressors are capable of delivering higher pressures, making them suitable for demanding applications that require greater air pressure.
Efficiency:
Two-stage compressors generally offer higher efficiency compared to single-stage compressors. The two-stage compression process allows for better heat dissipation between stages, reducing the chances of overheating and improving overall efficiency. Additionally, the two-stage design allows the compressor to achieve higher compression ratios while minimizing the work done by each stage, resulting in improved energy efficiency.
Intercooling:
Intercooling is a feature specific to two-stage compressors. Intercoolers are heat exchangers placed between the first and second compression stages. They cool down the partially compressed air before it enters the second stage, reducing the temperature and improving compression efficiency. The intercooling process helps to minimize heat buildup and reduces the potential for moisture condensation within the compressor system.
Applications:
The choice between a single-stage and two-stage compressor depends on the intended application. Single-stage compressors are commonly used for light-duty applications such as powering pneumatic tools, small-scale workshops, and DIY projects. Two-stage compressors are more suitable for heavy-duty applications that require higher pressures, such as industrial manufacturing, automotive service, and large-scale construction.
It is important to consider the specific requirements of the application, including required pressure levels, duty cycle, and anticipated air demand, when selecting between a single-stage and two-stage air compressor.
In summary, the main differences between single-stage and two-stage air compressors lie in the number of compression stages, pressure output, efficiency, intercooling capability, and application suitability.
