PET high-pressure blow molding air compressor is a high-pressure air supply equipment designed specifically for PET (polyethylene terephthalate) plastic bottle blow molding. It provides stable, clean high-pressure air (usually 25-40Bar) for heating the preform and then blowing it into shape.

RKA-1.0/40 | 1.0 | 40 | 15 | 790 | 1420*840*840 | 470 |
RKA-2.0/40 | 2.0 | 40 | 22 | 695 | 1800*850*1110 | 660 |
RKA-3.0/40 | 3.0 | 40 | 30 | 690 | 2020*935*1110 | 920 |
RKA-4.0/40 | 4.0 | 40 | 2*22 | 695 | 1800*1800*1110 | 1500 |
RKA-6.0/40 | 6.0 | 40 | 2*30 | 690 | 2020*1970*1110 | 2000 |
Product Features
●Air-cooling,low rotation speed,heavy-duty,energy-saving,durable.
● Material of valve plate all made of stainless steel.
● Multiple protection measures.
● When starting up,the solenoid valve is fully open and automatically drains and relive to ensure zero-pressure start.
● Equipment is safe and reliable,long maintenance intervals.
Applications
Widely used in blow molding machine,high pressure leakage testing,aerospace,ship and military industry field.
Common Asked Questions
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.
