Laser Cutting Auxiliary Screw Air Compressor
Why You Need a Dedicated Laser Cutting Air Compressor
Fiber laser cutting machines rely on assist gas to blow molten metal away from the cut kerf. Many fabricators use shop-wide compressed air that fluctuates in pressure and purity, causing inconsistent cut quality, dross buildup, and premature consumable wear. A dedicated screw air compressor solves this by delivering stable, clean, dry air at the exact pressure your laser cutting head requires—no matter what else is running on the shop floor.
Pressure Fluctuations
Shop air drops when other tools run, causing irregular cuts and dross on the bottom edge of your parts.
Oil & Moisture Damage
Contaminated air clogs protective lenses and nozzles, increasing consumable costs and unplanned downtime.
High Operating Costs
Oversized or old piston compressors waste energy and require frequent maintenance.
Noise & Heat
Compressor noise disrupts the workshop environment and excess heat affects nearby precision equipment.
Product Overview
This industrial screw air compressor is purpose-built for fiber laser cutting assist gas supply. It pairs a precision-machined twin-screw airend with an integrated refrigerated air dryer and multi-stage filtration system, delivering oil-free, dry compressed air at stable pressure. The unit is engineered to work seamlessly with Xinhong's PSA nitrogen generator—providing the clean, dry feed air that PSA systems require to produce high-purity nitrogen for cutting stainless steel and aluminum. Available in multiple flow capacities, it scales from small job shops to high-volume 24/7 production lines.
Core Features & Advantages
Twin-Screw Airend with Direct Drive
Precision-ground rotors and direct coupling to the motor eliminate belt slippage, maintaining ±0.02 MPa pressure stability even under intermittent load—ensuring consistent cut edge quality across long production runs.
Integrated Refrigerated Dryer + 3-Stage Filtration
Built-in refrigerated dryer reduces dew point to 2–10°C, while pre-filter, fine filter, and activated carbon filter stages bring oil content below 3 ppm and particulate below 0.01 μm. Protects laser cutting lenses, nozzles, and gas lines from contamination.
VFD Variable Frequency Control
Variable frequency drive adjusts motor speed to match real-time air demand, reducing energy consumption by 20–35% compared to fixed-speed compressors. No-load shutdown after prolonged idle periods saves additional power.
Sound-Enclosed Cabinet Design
Fully enclosed cabinet with sound-absorbing foam lining keeps operating noise at or below 62 dB(A) at 1 meter—suitable for installation directly next to laser cutting equipment without disrupting workshop operations.
PLC Controller with Remote Monitoring
Schneider Electric PLC provides real-time pressure, temperature, and running hours display. Fault alarms for high temperature, low pressure, and motor overload protect your investment. RS485 interface enables integration with factory monitoring systems.

FAQ
What size compressor do I need for my laser cutting machine?
It depends on your laser power and cutting material. For assist air cutting (carbon steel), 1.3–2.0 m³/min at 0.7–1.0 MPa typically suits 1000W–3000W machines. For higher-power machines or when feeding a PSA nitrogen generator, 2.5–3.5 m³/min at 1.0–1.3 MPa is recommended. Share your machine specs and we'll recommend the right model.
Can this compressor feed a PSA nitrogen generator?
Yes. The integrated refrigerated dryer and multi-stage filtration produce clean, dry air that meets PSA nitrogen generator input requirements. When paired with Xinhong's nitrogen generator, it forms a complete cutting gas solution—producing nitrogen at 99.9% purity from atmospheric air.
How often does maintenance need to be performed?
Routine maintenance includes oil and oil filter replacement every 4000–8000 operating hours, air filter element cleaning/replacement monthly, and filter cartridge inspection quarterly. The PLC displays running hours and maintenance reminders automatically.
Do you offer customization for voltage and frequency?
Yes. Standard units are 380V/50Hz/3-phase, but we can customize to 460V/60Hz or other regional power standards. Let us know your facility's power specifications when inquiring.
What warranty and after-sales support do you provide?
The compressor comes with a standard 12-month warranty. Remote technical support, spare parts supply, and installation guidance are available. As a full-line laser equipment manufacturer, Xinhong can provide integrated support for your entire cutting system.
