Medium Pressure Screw Compressor

When 13 bar is not enough and 350 bar is too much, this compressor fills the gap. It delivers air at 15 to 40 bar for laser cutting, PET bottle blowing, and other processes that need higher-than-standard pressure.

About This Product

Standard screw compressors top out at 13 bar. Piston compressors can go higher but are loud and produce pulsating air. This medium-pressure screw compressor fills the space between them with smooth, high-volume air at 15–40 bar.

The design uses two-stage screw compression. The first stage brings air to an intermediate pressure, an intercooler removes heat, and the second stage compresses to the final set pressure.

Fiber laser cutting machines typically need 16–20 bar of clean, dry air. PET bottle blowing pre-forms use 25–40 bar. This machine serves both applications.

Technical Advantages

Laser-Grade Air Quality

With an optional precision filter package, outlet air reaches ISO 8573-1 Class 1.2.1 for moisture, oil, and particles.

Stable Pressure at 40 Bar

The controller maintains discharge pressure within ±0.5 bar. PET blowing machines need this stability for consistent bottle wall thickness.

Aftercooler Included

An oversized aftercooler brings the discharge temperature to within 10°C of ambient before the air leaves the machine.
