This high-pressure, oil-free air compression unit, rated at 40 bar and 5 m³/min, is engineered for PET bottle blow molding.
Product features
1. 100% Oil‑Free – ISO 8573‑1 Class 0 Certified
The compression chamber uses water as the sole medium for sealing and cooling, eliminating any oil contamination risk.
Output air meets the strictest purity standards (ISO 8573‑1 Class 0), with oil content below 0.01 mg/m³. This makes it an
ideal choice for food‑grade PET preform production, beverage filling lines, and pharmaceutical environments.
2. Steady 40 Bar High‑Pressure Output
The unit maintains a stable 40 bar discharge with minimal fluctuation, ensuring consistent preform expansion and uniform
wall thickness. It supplies high‑pressure air directly to blow molding equipment, removing the need for an additional booster.
3. Significant Energy Savings
By using water injection for near‑isothermal compression, this system consumes 15–25% less energy than single‑stage
alternatives, while delivering up to 20% greater airflow at the same motor rating. With PM VFD technology, partial‑load
energy use is reduced by another 15–25%.
4. Cooler Running – Longer Life
Water’s superior heat absorption keeps operating temperatures lower than oil‑based designs, boosting equipment
reliability and extending service life.
5. Minimal Maintenance Requirements
No oil filters, separators, or oil changes — and zero waste oil disposal. Service tasks are limited to periodic water filter
replacements and standard inspections. The absence of carbon or sludge deposits prolongs air end life, and
consumables are few and easy to replace.
6. Quiet, Low‑Vibration Performance
Water effectively dampens noise and vibration, making the unit noticeably quieter than dry‑running or piston compressors.
Smooth, pulse‑free airflow improves the working environment and reduces wear on downstream components.
7. Designed for Continuous 24/7 Operation
Built for non‑stop duty with food‑grade stainless steel and premium bearings. The automatic water exchange function permits
maintenance without interrupting production.
8. Intelligent Controls & Remote Access
A PLC with HMI touchscreen enables full digital automation. Cloud‑based monitoring and predictive diagnostics minimize
unplanned downtime, while IoT connectivity supports seamless Industry 4.0 integration.
