Large PET bottle production can often consume great quantities of high and low pressure air. A primary booster system provides flexibility to meet changing demands. The Ingersoll Rand primary booster system provides a modular approach that features a primary compressor augmented by a booster. The primary compressor can be an oil-free rotary or centrifugal compressor matched to your needs, while a two-stage, non-lubricated reciprocating compressor serves as the booster to easily adjust system capacity when demand changes.
