Laser Cutting Air Compressor

Fiber laser cutting machines use high-pressure compressed air as the assist gas to blow molten metal out of the cut. This compressor provides 16–40 bar of clean, dry, oil-free air directly to the laser head.

Why Choose This Product

Complete Air Preparation

Compressor, dryers, and filters are integrated in one unit. No need to assemble a separate air treatment chain.

Pressure Matched to Laser

Select the pressure rating to match your laser cutter. A 3kW machine cutting thin steel needs 16 bar. A 20kW machine cutting 25mm carbon steel needs 30–40 bar.

Automatic Drain and Monitoring

The system drains condensate automatically and displays filter condition on the control panel. An alarm sounds when filters need replacement.

How It Works

When a fiber laser cuts carbon steel with air assist, the air pressure at the nozzle determines cut speed and edge quality. Low-power lasers (1–3kW) need 12–16 bar. High-power lasers (6–30kW) need 20–40 bar.

This compressor is packaged as a complete air preparation system: a two-stage screw compressor, a refrigerated dryer, a heated desiccant dryer, and three stages of filtration. The output is ISO 8573-1 Class 1.2.1 — meaning particles below 0.1 mg/m³, dew point below -40°C, and oil below 0.01 mg/m³.

Without this level of air quality, the laser nozzle clogs, cut quality drops, and the laser optics can be damaged by oil or moisture in the air stream.
