Core Advantages
✅ Efficient and Stable: Quickly responds to pressure demands, ensuring uninterrupted production
✅ Energy-Saving: Utilizes variable frequency technology, saving 20%-30% energy compared to traditional models
✅ Oil-Free and Clean: 100% oil-free compression, preventing oil contamination of bottles (FDA/ISO certified)
✅ Intelligent Control: PLC automatically adjusts pressure to meet the production needs of different bottle shapes
✅ Low Maintenance: Modular design allows for easy filter replacement, minimizing downtime
Main Applications
Beverage Industry: Mineral water bottles, carbonated beverage bottles, and juice bottles
Daily Chemical Packaging: PET packaging for shampoo, shower gel, and other products
Food Packaging: Blow molding of cooking oil and condiment bottles
Pharmaceutical Packaging: Aseptic blow molding of oral liquid and medicine bottles
FAQ
Q1: What pressure is required?
A: Typically 25-40 bar, depending on preform size and mold design.
Q2: Is oil-free air required?
A: Yes. Food- and pharmaceutical-grade PET bottles require oil-free air to avoid contamination.
Q3: How do you ensure dry air?
A: A refrigerated or adsorption dryer with a dew point of ≤-40°C is required.
Q4: How many blow molding machines can one machine power?
A: It depends on the compressor flow rate (e.g., a 110kW model can support 2-4 dual-mode blow molding machines).
Q5: What is the maintenance interval?
A: The primary filter element should be replaced every 500 hours, and the fine filter element every 2000 hours.
