High-pressure Industrial Air Compressors
ProFlow HP - 40 BAR High-Pressure Piston Air Compressors
A 40 BAR PET piston air compressor is a heavy-duty industrial machine that compresses air up to 40 bar (about 580 psi) using reciprocating pistons. It is built specifically to supply clean, high-pressure air for stretch blow-molding machines that manufacture plastic PET bottles and containers.

Key Features and Design
- Multi-Stage Compression: The air is compressed in two or three separate sequential steps (stages). Each stage raises the pressure higher (for example: atmospheric to 5 bar, then 15 bar, and finally 40 bar).
- Intercooling: Coolers are placed between each stage to remove heat and moisture build-up caused by high compression.
Main Uses
- PET Bottle Blowing: Provides the extreme, high-pressure blast of air required to expand plastic preforms into final bottle molds.
- Pre-blowing and Actuation: Supplies stable air pressure for initial pre-blowing stages and operating internal machine valves.
Core Benefits
- High Efficiency: Multi-stage piston setups reach high pressure levels efficiently..
- Durable Build: Engineered for continuous, heavy factory workloads with low rotational speeds to reduce wear. Clean Output: Guarantees pure air that protects product safety and prevents container contamination.

Two-Stage
Air Compressors (ProFlow HP)
The compressor is compact with an air cooling system and efficient intermediate and post-cooling coolers. The system includes a low oil level protection mechanism to detect
oil shortages and trigger a shutdown procedure.
An optional air tank
is available (standard compressors are supplied without one).
Medium and High-pressure
Air Compressors (ProFlow HP)
After years of development, ProFlow HP produces medium and highpressure air compressors with sustainable operation and stable performance. These have been applied in various industries and sold internationally.
The ProFlow HP compressor is characterised by significant economic and energy savings.
Three-Stage
Air Compressors (ProFlow HP)
Annular valves has advantages of good sealing, small leakage,
improving suction efficiency and reducing energy consumption.
The compressor is equipped with an efficient high-pressure inlet
and outlet valve. The inlet valve also features a 4-micron air filter to ensure the air purity.
Energy-saving Booster Series
Air Compressor (ProFlow HP)
The air-end of the ProFlow HP compressor is designed as a
multi-stages booster compression, air cooling and belt-driven
system.
ProFlow HP booster can utilize multi-stage compression for various
gases including air, nitrogen and helium.
Premium Detroit Rotary Screw Air Compressors
A rotary screw air compressor is a common type of industrial gas compressor that uses two interlocking, rotating helical screws (called rotors) to trap and continuously squeeze air into a smaller space, raising its pressure.

After Cooler
Top mounted for efficient cooling and easy cleaning. The top panel is removable allowing easya ccess to the cooler from the bottom and top. Cabinet disassembly is quick.
Silent Operation
The acoustically dampened cabinet design utilises intelligent technology to keep operational noise inside the cabinet ensuring you a silent and vibration-free operation.
Practical Design
Intelligent unit design focuses on efficiency of the placement of internal components, this allows for eacy and quick replacement and cleaning of service parts and spares.
Detroit Rotary Screw Compressor Features
- Intelligent PLC Control System
This system allows full customisation of the system air output and delivery by the user. The PLC is able to Integrate with various IT solutions offering the user full remote control and system monitoring.
- Cabinet
European design and maintenance focused configuration for quick servicing and less downtime. This allows for reduced maintenance costs and less production loss, contributing to a very low total cost of ownership.
- Air-end
Long bearing life and energy efficiency are core design elements of the new generation of DB air-ends. The DB series provides rock-solid performance coupled with a very long design life. SKF bearings are used and the RPM of the rotors are kept as low as possible. High-tech production machinery ensures consistent quality and superior air delivery.
- Visual Warning System
VWS Is designed to provide a visual indication of the machine’s operating status in noisy environments. This system uses industrial grade LED strip lights to show the current status of the machine through various colours. The system Is programmed to display various colours for normal, fault, service, and emergency operational status (not available in all markets).
- Directly Driven Motor Structure
This allows for the direct trasnfer of energy to the air-end master rotor, increasing efficiency and reducing vibration. This system is used from 10HP up to50HP in an 8 or 10 bar pressure output, larger machines using a directly coupled transfer system. Belt drive configuration is available on request.
- Electric Motor
Electrical efficiency and performance stability are key points in the design of the DB range of screw compressors, as is motor protection. All DB screw featured full PLC motor protection which covers low/high voltage, high current, high temperature, open phase, reverse phase and overload situations.
