• Low maintenance cost

Questions and Answers

1. Why must a laser cutting machine use a "dedicated" screw compressor? Can't a regular screw compressor be used?
The key differences lie in the post-processing system configuration and pressure and flow compatibility. Using a regular screw compressor directly can lead to pitfalls:

• Insufficient dryness: Regular compressors are often equipped with a conventional dryer (dew point typically ≤ -20°C), while laser cutting requires compressed air with a dew point ≤ -40°C (otherwise, during high-temperature cutting, moisture in the air will vaporize, damaging the laser lens and reducing cutting accuracy).
• Insufficient cleanliness: Regular compressor filters typically have a filtration accuracy of 3-5μm, while dedicated compressors come standard with a 1μm pre-filter, a 0.01μm fine filter, and an activated carbon degreasing filter to prevent oil mist and dust from entering the laser air path.
• Poor pressure compatibility: The typical pressure for laser cutting is 0.6-0.8MPa, while a dedicated compressor has a pressure control accuracy of ±0.02MPa (regular compressors may experience fluctuations of up to ±0.05MPa). Unstable pressure can lead to inconsistent cutting speeds and uneven cross-sections.

2. My laser cutting machine frequently reports an "Insufficient Air Pressure" error during operation, but the air compressor indicates normal pressure. What's going on?

This is most likely due to "air line loss" or "partial blockage." Troubleshoot as follows:

• Check the piping from the air compressor to the laser machine. If the piping is too long (over 10 meters) or too thin (less than DN25), pressure loss may occur (for example, if the pressure at the compressor outlet is 0.8 MPa, only 0.6 MPa remains at the laser head). Replace the piping with a thicker diameter or shorten the distance.
• Check the post-processing filters. If the pre-filter, fine filter, or dryer filter is clogged (especially in dusty or humid cutting environments), "false pressure" may occur (the air compressor indicates adequate pressure, but insufficient air flow). These filters need to be removed, cleaned, or replaced.
• Check the laser machine's air valves. If the laser head's air inlet valve or pressure regulator is stuck or leaking, insufficient air supply pressure may result. Disassemble and clean the valves or replace the seals.
