| Oil content | The compressed air has an oil content of 0PPM and has passed the third-party international authoritative organization TUV class 0 oil-free certification in Germany | When the oil scraper ring and packing box are worn out, lubricating oil will enter the cylinder in a gaseous or liquid form, causing the discharged compressed air to contain oil |
| Operational security | When shutting down: the pressure is relieved by the vent valve, and there is no pressure in the compression chamber. When restarting, it can be started directly | When restarting, it is necessary to use low-pressure air to open the air valve for unloading, which poses a risk of equipment failure due to improper operation |
| Vibration | Good power balance, smooth operation, no need to fix the foundation during the operation of the unit, and the coin does not tilt | Unbalanced force, large vibration, requiring fixed foundation or shock absorption device |
| Oil free safety | 100% clean and oil-free compressed air, 100% avoiding the risk of oil pollution | There is a risk of lubricating oil leaking into the compression chamber and spraying a large amount of oil after the failure of the oil scraper ring and the wear of the packing box create gaps |
| Water content | Isothermal compression, the compression chamber temperature is generally only around 45 ºC, and the water vapor mixture is separated by a patented water vapor separation drum, resulting in low water content in the compressed air | The working temperature of the compression chamber of the piston machine is around 180 ºC, and the exhaust temperature after passing through the aftercooler is around 85 ºC. The compressed air has a high water content |
| Fire safety | The operating temperature is low, around 45 ºC, so there is no need to worry about equipment high-temperature self ignition or scalding accidents | The temperature of the compression chamber can reach around 180 ºC, which poses a risk of high-temperature spontaneous combustion and personal burns. |
| Temperature | The whole machine is cooled by water, and as long as the pressure and flow rate of the cooling water are ensured, the machine can operate stably at around 45 ºC for a long time | The temperature inside the cylinder is around 180 ºC, which is prone to high temperature alarm and shutdown |
| Efficiency | The direct connection between the host and motor has high transmission efficiency and low power loss, with a compression efficiency of over 95% | The reciprocating plug type is generally a three-stage or 4 stage compression, with a complex structure and pipelines, high pressure loss, high specific power, and high power consumption |
| Particle impurities | Water has a cleaning effect on the air. Impurities such as dust particles sucked in with the air remain in the water and are discharged from the machine body through an automatic drainage and discharge valve | The dust particles sucked in with the air and impurities such as dust particles that fall off from the friction of moving parts are compressed together |
| Corrosive gas content | The corrosive gases in the air are cleaned with pure water, left in the water, and discharged from the machine body through an automatic drainage valve | The corrosive gases in the air are directly compressed and enter the machine, causing corrosion to the cast iron, ductile iron cylinders, and components of the piston compressor |
| Maintenance costs | Low, taking the CHINAMFG with an installed power of 150kw as an example, the annual maintenance cost does not exceed ¥20000 | Taking a piston engine with an installed power of 150kw as an example, the annual maintenance cost is around ¥100000 |
| Maintenance consumables and accessories | Water filter cartridge, air filter | Oil coarse filter, oil fine filter, air valve, piston ring, support ring, oil scraper ring, packing, bearing shell, etc |
| Hygiene and cleanliness | All components in contact with water and air are made of 304 or 316 food grade stainless steel, ensuring food grade safety, cleanliness, and hygiene. | Most components in contact with water and air are made of ductile iron, cast iron, aluminum, or carbon steel, which are prone to corrosion, rust, and pollution of compressed air |
| Operating energy consumption and electricity bills | The screw machine is a high-speed and light load machine, which saves about 20% energy compared to the piston machine when all new machines are used | Low speed heavy load, high power consumption |
| Noise | Low noise, taking the 242kw model as an example, the noise is around 80 decibels | High noise, taking the 250kw model as an example, the noise is about 110 decibels |

How do you choose the right air compressor for woodworking?
Choosing the right air compressor for woodworking is essential to ensure efficient and effective operation of pneumatic tools and equipment. Here are some factors to consider when selecting an air compressor for woodworking:
1. Required Air Volume (CFM):
Determine the required air volume or cubic feet per minute (CFM) for your woodworking tools and equipment. Different tools have varying CFM requirements, so it is crucial to choose an air compressor that can deliver the required CFM to power your tools effectively. Make sure to consider the highest CFM requirement among the tools you’ll be using simultaneously.
2. Tank Size:
Consider the tank size of the air compressor. A larger tank allows for more stored air, which can be beneficial when using tools that require short bursts of high air volume. It helps maintain a consistent air supply and reduces the frequency of the compressor cycling on and off. However, if you have tools with continuous high CFM demands, a larger tank may not be as critical.
3. Maximum Pressure (PSI):
Check the maximum pressure (PSI) rating of the air compressor. Woodworking tools typically operate within a specific PSI range, so ensure that the compressor can provide the required pressure. It is advisable to choose an air compressor with a higher maximum PSI rating to accommodate any future tool upgrades or changes in your woodworking needs.
4. Noise Level:
Consider the noise level of the air compressor, especially if you’ll be using it in a residential or shared workspace. Some air compressors have noise-reducing features or are designed to operate quietly, making them more suitable for woodworking environments where noise control is important.
5. Portability:
Assess the portability requirements of your woodworking projects. If you need to move the air compressor frequently or work in different locations, a portable and lightweight compressor may be preferable. However, if the compressor will remain stationary in a workshop, a larger, stationary model might be more suitable.
6. Power Source:
Determine the power source available in your woodworking workspace. Air compressors can be powered by electricity or gasoline engines. If electricity is readily available, an electric compressor may be more convenient and cost-effective. Gasoline-powered compressors offer greater flexibility for remote or outdoor woodworking projects where electricity may not be accessible.
7. Quality and Reliability:
Choose an air compressor from a reputable manufacturer known for producing reliable and high-quality equipment. Read customer reviews and consider the warranty and after-sales support offered by the manufacturer to ensure long-term satisfaction and reliability.
8. Budget:
Consider your budget and balance it with the features and specifications required for your woodworking needs. While it’s important to invest in a reliable and suitable air compressor, there are options available at various price points to accommodate different budgets.
By considering these factors and evaluating your specific woodworking requirements, you can choose an air compressor that meets the demands of your tools, provides efficient performance, and enhances your woodworking experience.

What is the difference between a piston and rotary screw compressor?
Piston compressors and rotary screw compressors are two common types of air compressors with distinct differences in their design and operation. Here’s a detailed explanation of the differences between these two compressor types:
1. Operating Principle:
- Piston Compressors: Piston compressors, also known as reciprocating compressors, use one or more pistons driven by a crankshaft to compress air. The piston moves up and down within a cylinder, creating a vacuum during the intake stroke and compressing the air during the compression stroke.
- Rotary Screw Compressors: Rotary screw compressors utilize two intermeshing screws (rotors) to compress air. As the male and female screws rotate, the air is trapped between them and gradually compressed as it moves along the screw threads.
2. Compression Method:
- Piston Compressors: Piston compressors achieve compression through a positive displacement process. The air is drawn into the cylinder and compressed as the piston moves back and forth. The compression is intermittent, occurring in discrete cycles.
- Rotary Screw Compressors: Rotary screw compressors also employ a positive displacement method. The compression is continuous as the rotating screws create a continuous flow of air and compress it gradually as it moves along the screw threads.
3. Efficiency:
- Piston Compressors: Piston compressors are known for their high efficiency at lower flow rates and higher pressures. They are well-suited for applications that require intermittent or variable air demand.
- Rotary Screw Compressors: Rotary screw compressors are highly efficient for continuous operation and are designed to handle higher flow rates. They are often used in applications with a constant or steady air demand.
4. Noise Level:
- Piston Compressors: Piston compressors tend to generate more noise during operation due to the reciprocating motion of the pistons and valves.
- Rotary Screw Compressors: Rotary screw compressors are generally quieter in operation compared to piston compressors. The smooth rotation of the screws contributes to reduced noise levels.
5. Maintenance:
- Piston Compressors: Piston compressors typically require more frequent maintenance due to the higher number of moving parts, such as pistons, valves, and rings.
- Rotary Screw Compressors: Rotary screw compressors have fewer moving parts, resulting in lower maintenance requirements. They often have longer service intervals and can operate continuously for extended periods without significant maintenance.
6. Size and Portability:
- Piston Compressors: Piston compressors are available in both smaller portable models and larger stationary units. Portable piston compressors are commonly used in construction, automotive, and DIY applications.
- Rotary Screw Compressors: Rotary screw compressors are typically larger and more suitable for stationary installations in industrial and commercial settings. They are less commonly used in portable applications.
These are some of the key differences between piston compressors and rotary screw compressors. The choice between the two depends on factors such as required flow rate, pressure, duty cycle, efficiency, noise level, maintenance needs, and specific application requirements.
