Laser Cutting Air Compressors

The assist gas pressure in laser cutting directly affects whether the cut edge has dross and whether the cut face turns yellow. Insufficient pressure leaves slag that cannot be blown clear, while pressure that rises and falls makes a consistent cut face impossible. The firstAir brand offers two laser cutting models: FASM-16, FASM-16F and FAS-16F, all with a working pressure of 1.6 MPa. They share the F-prefixed naming and similar maintenance logic with other firstAir screw series, making it easy to configure a complete set within one brand.

Why a Stable 1.6 MPa Air Source Is Critical

Laser cutting models generally place more emphasis on pressure rating than general-purpose models, because pressure fluctuation during cutting is reflected directly in cut quality. The 1.6 MPa working pressure of the FASM-16 and FAS-16F leaves margin for high-pressure cutting processes; air delivery covers 0.3–3.80 m³/min and 0.60–3.80 m³/min respectively, with power of 7.5–37 kW, matching configurations from a single cutting machine to several.

VSD Path and Economy Path

The FASM-16 and FASM-16F use PM VSD starting and coaxial direct drive: when air use falls during piercing, idle travel or waiting stages, speed drops accordingly, air output tracks demand and pressure fluctuation is smaller; the coaxial direct drive eliminates the routine maintenance of belt tensioning and replacement. The FAS-16F is an integrated model dedicated to laser cutting, using Y-△ starting and belt drive, with a more economical approach, suited to applications with relatively stable demand that are sensitive to initial investment. Both offer full-performance models, with a rated pressure dew point of 2–10 °C.

Technical Specifications

Selection and Air Treatment

1. First confirm the pressure the cutting process requires; 1.6 MPa is the upper limit of capability, so take the point of use as the basis;
2. With many cutting machines and pronounced demand fluctuation, give priority to the PM VSD FASM-16 series;
3. With stable demand and a tight budget, evaluate the integrated FAS-16F;
4. Configure drying and filtration at the same time, according to the process requirements for dew point and dust content.
