Key Features & Advantages
1. High-Pressure Output
Provides exhaust pressures up to 20 bar, meeting the high-pressure nitrogen/oxygen requirements of high-power laser cutting machines exceeding 3000W and even 10,000W. This ensures smooth cross-sections, faster speeds, and higher efficiency when cutting thick plates.
2. Highly Integrated
The all-in-one design eliminates the tedious process of purchasing and piping separate air compressors, dryers, filters, and other components. Its compact footprint and easy, plug-and-play installation significantly reduce installation costs.
3. High-Quality Air Output
A built-in multi-stage precision filter and refrigerated dryer effectively remove oil, moisture, dust, and particulate matter from the compressed air, providing pure, dry compressed air.
4. Energy-Efficient
Typically utilizes permanent magnet variable frequency (PMVF) technology. It automatically adjusts motor speed and power output based on the actual air consumption of the laser cutting machine. This maintains stable air pressure, avoids energy waste caused by frequent loading and unloading, and significantly reduces energy consumption, making it particularly suitable for operating conditions with fluctuating air consumption.
5. Intelligent Control
Equipped with an advanced intelligent control system featuring a human-machine interface, it provides real-time monitoring of pressure, temperature, operating status, maintenance reminders, and more. It also supports remote control and fault diagnosis, making operation and management convenient.
6. Stability and Reliability
The screw extruder boasts a sophisticated design, offering smooth operation, minimal vibration, and low noise, making it suitable for long-term, continuous operation in workshop environments.
Applications
1. Use high-power (3000W and above) laser cutting machines.
2. Process large quantities of materials such as stainless steel and aluminum alloys that require inert gas (nitrogen) shielding.
3. Frequently cut medium-thick metal sheets (>15mm).
4. Require extremely high cutting quality and precision.
5. Operate on a large scale, prioritizing production efficiency and equipment stability and reliability.
FAQ
Q1: Why does laser cutting require such high pressure (20 bar)? Wouldn't a regular air compressor be sufficient?
A: No. High-power lasers cutting thick metal plates require extremely high gas pressure and flow to quickly penetrate the molten metal and create high-quality kerfs. The pressure and flow of regular air compressors (typically <13 bar) cannot meet these requirements, resulting in slow cutting speeds, rough cut surfaces, heavy dross, and even incomplete cutting. A high pressure of 20 bar is essential for optimal cutting performance.
Q2: What are the advantages of an integrated laser versus a split laser?
A: The advantages are:
• Effortless and hassle-free: No need to select and assemble post-processing equipment yourself, eliminating compatibility risks.
• Space-saving: The integrated design is compact.
• Guaranteed results: All commissioning and matching are completed before shipment to ensure complete purification.
Q3: Can the air source generated by this laser be used directly for laser cutting?
A: Yes. The all-in-one unit's built-in drying and filtration system is designed to treat compressed air to the quality required for laser cutting. The resulting air can be directly connected to the laser cutting machine's air system.
Q4: What are the main cost considerations for purchasing this type of air compressor?
A: Consider not just the initial purchase cost but the full lifecycle cost:
• Initial purchase cost: All-in-one units are generally more expensive than self-assembly.
• Energy cost: This is the largest cost. The permanent magnet variable frequency drive function can significantly save electricity, making it very cost-effective in the long run.
• Maintenance cost: Regular replacement of the three filters, one oil filter, and consumable parts.
• Downtime loss: High-quality equipment offers excellent stability and a low failure rate, reducing losses caused by production interruptions.
Q5: What routine maintenance is required?
A: Key maintenance tasks include:
• Daily: Check for leaks and check the control panel for alarms.
• Periodic (based on operating hours):
◦ Replace the air filter element (affects intake air quality).
◦ Replace the oil filter (to ensure lubricating oil is clean). ◦ Replace the oil-gas separator element (to reduce exhaust oil content).
◦ Replace the lubricating oil (for cooling, sealing, and lubrication).
◦ Inspect and replace the precision filter element (to ensure final air quality).
Q6: How should I select a laser cutting machine? What power level do I need?
A: The selection process is primarily based on the following:
The power and number of laser cutting machines: The higher the power, the greater the air consumption. Refer to the air compressor's exhaust volume specifications to ensure that the total air supply exceeds the combined maximum air consumption of all laser equipment, with a margin.
Cutting material and process: The air consumption differs when cutting carbon steel (using oxygen) and stainless steel (using high-purity nitrogen). Nitrogen consumption is generally higher, requiring a higher air compressor output volume.
