All-round carefree package for PET container production
The SIGMA PET AIR complete booster system combines blow and control air production in a single operation-ready system. An air-cooled rotary screw compressor produces the control air whilst simultaneously serving as a pre-compression stage for the blow air. Blow air booster, system controller and all compressed air treatment components for both pressure systems are installed operation-ready on a base frame.

SIGMA PET AIR delivers the following performance parameters:

Flow rate up to 2772 m³/h
Blow air up to 45 bar
The SIGMA PET AIR complete booster system is the perfect choice for operators of PET container blow-moulding equipment with high expectations when it comes to reliability, cost-effectiveness and compressed air quality.

Your advantages

Rapid delivery, ready for immediate operation:
Installation on a base frame reduces the unit footprint whilst also streamlining transport and setup. We are also capable of delivering complete, operation-ready SIGMA PET AIR systems installed in containers if desired by the customer.
Unparalleled cooling without high cost:
The majority of our boosters are equipped with air-cooled aftercoolers. In air-cooled units, a separate cooler with its own fan motor ensures minimal temperature differential (ΔT) between the intake air and compressed air, allowing customers to dispense with expensive water-cooled systems.
Benefit from low maintenance requirements:
Since the SIGMA PET AIR system has only two compression stages (rotary screw compressor and booster), significantly less service is required compared to multi-stage high-pressure reciprocating compressors with atmospheric compression.
