A 40 bar 5 m³/min oil-free water-lubricated screw air compressor is a high-pressure, oil-free compressed air system specifically engineered for PET bottle blow molding applications.
Product features
100% Oil-Free – ISO 8573-1 Class 0 Certified
Water is the only lubricant in the compression chamber – no oil contact, no contamination. Oil content below 0.01 mg/m³. Ideal for food, beverage, and pharmaceutical applications.
High-Pressure Stability at 40 Bar
Delivers steady 40 bar output with minimal fluctuation for uniform bottle quality. No additional booster needed – direct high-pressure supply for blow molding.
Superior Energy Efficiency
Near‑isothermal compression saves 15–25% energy vs. single‑stage units, with up to 20% higher airflow at the same motor rating. PM VFD adds another 15–25% savings at partial loads.
Low Operating Temperatures – Extended Life
Water cools more effectively than oil, keeping running temperatures low – improving reliability and extending service life.
Low Maintenance – Simplified Service
No oil, no oil filters, no separators, no waste oil disposal. Only periodic water filter changes. No carbon buildup – fewer consumables, easy parts replacement.
Quiet & Low Vibration
Water absorbs vibration and noise – significantly quieter than dry or piston units. Smooth operation improves the work environment and reduces wear.
24/7 Continuous Operation
Built for round‑the‑clock use with food‑grade stainless steel and imported bearings. Automatic water changing allows maintenance without stopping production.
Intelligent Control & Remote Monitoring
PLC with HMI touchscreen for full digital control. Cloud monitoring and IoT connectivity enable predictive maintenance and Industry 4.0 integration.
