A PET air compressor is a long-term capital asset, so the buying decision should survive contact with real production data. This guide walks beverage and bottled-water operators through the variables that actually matter when specifying CMN's water-lubricated single-screw compressors.
Before comparing prices, lock the purity requirement.
For PET blowing, ISO 8573-1 Class 0 is the safe target.
CMN's TÜV certification to ISO 8573-1:2010 Class 0 confirms zero oil.
A PET air compressor without documented Class 0 exposes the brand to risk.
Different bottles and preforms demand different medium pressures. CMN's range spans 2–40 bar, with medium-pressure PET variants in the upper band.
Single-serve water: lower medium pressure.
Carbonated and hot-fill bottles: check the blow-mold spec.
Always size to the highest required pressure, not the average.
Input | Why it matters |
Blow heads count | Sets simultaneous demand |
Cycle time | Sets peak m³/min |
Future lines | Avoids early replacement |
CMN models scale from CM75GPV to CM320GPV, so you can match capacity without overbuying.
A PET air compressor on a variable-demand line benefits from permanent-magnet variable-speed drive.
PMVSD trims energy when demand dips below peak.
It reduces wear from constant start-stop cycling.
CMN GPV models integrate PMVSD with the controller.
Ask the supplier:
Are assemblies modular for fast swap?
Are spares documented per model?
Is remote diagnostics available?
CMN supports these across its full water-lubricated range and has field experience from exhibitions such as CBST2025 and shipments to Korea.
A sound PET air compressor purchase starts with Class 0 air, matches pressure and peak flow, and uses PMVSD to control lifetime energy cost. CMN's water-lubricated single-screw line gives beverage plants a certified, serviceable path from pilot line to full plant.
