PET Bottle Blowing Compressors: Medium-Pressure Class 0

PET bottle blowing compressors live at the intersection of two demands: enough medium pressure to form the bottle, and enough purity to keep it safe for consumption. CMN's water-lubricated single-screw compressors are purpose-built for exactly this duty, with TÜV ISO 8573-1:2010 Class 0 certification and a pressure range reaching 40 bar.

Medium Pressure, Defined for PET

"Medium pressure" in this context means the band above standard plant air but below high-pressure industrial duties.

• CMN's water-lubricated range spans 2–40 bar.

• Dedicated PET bottle blowing compressors sit in the medium-pressure upper portion.

• Stable pressure at the mold prevents incomplete or inconsistent bottles.

Class 0 as the Baseline

For blowing, air purity is not a premium feature — it is the product.

• Class 0 is the strictest ISO 8573-1 purity class (zero oil).

• CMN's certification is TÜV-verified to ISO 8573-1:2010.

• Water lubrication removes oil from the chamber, so purity is designed in.

CMN Model Options

Energy Control on Blowing Lines

Blow demand rises and falls with line speed. PMVSD-driven PET bottle blowing compressors from CMN modulate output to match, avoiding the energy penalty of constant full-load running.

Conclusion

PET bottle blowing compressors must deliver medium-pressure, certified oil-free air without exception. CMN's water-lubricated single-screw models combine Class 0 purity, up to 40 bar, and PMVSD efficiency for reliable bottling.
