Product features

1. ISO 8573‑1 Class 0 Oil-Free Certified
Delivers 100% oil‑free compressed air – zero oil aerosol, vapor, or liquid. Meets the strictest purity standards for food, beverage, and pharmaceutical PET packaging.

2. 4.0 MPa (40 bar / 580 psi) High Pressure
Specifically engineered for PET stretch‑blow moulding. Ensures stable, consistent pressure for uniform wall thickness and minimal reject rates.

3. 160 kW High-Power Drive
Provides ample power for medium‑to‑large scale production lines. Supports multiple blow‑moulding machines simultaneously without pressure drop.

4. Multi‑Stage Compression with Intercooling
Optimises energy efficiency across each compression stage. Reduces specific power consumption (kW per cfm) compared to single‑stage designs.

5. Variable Frequency Drive (VFD) Optional
Adjusts motor speed to match real‑time air demand. Cuts energy consumption by 25%–40% versus fixed‑speed units.

6. 24/7 Continuous Duty Design
Built for round‑the‑clock operation in demanding industrial environments. Extended maintenance intervals reduce downtime and operating costs.

7. Compact, Skid‑Mounted Package
Small footprint, pre‑piped, pre‑wired – simplifies installation. No special foundation required; quick integration into existing production lines.
