PET bottle blowing needs a large volume of clean, dry air at two distinct pressure levels, making compressor selection specific to the line.
High and Low Pressure Demand
Low pressure air moves preforms and operates valves, while high pressure air stretches and forms the bottle in the mould.
Air Quality Needs
Oil and moisture cause bottle defects and mould fouling. Filtration and drying are essential for stable quality.
Recommended Setup
Match the compressor, dryer, filtration and receiver to the blowing machine’s pressure and flow curve, and plan for peak cycles.
