Non-Lubricated Three Stage PET Compressor

100 % Oil Free High Pressure Air Compressor Balanced Opposed, Double Acting, Watercooled, Three Stage Oil Free Compressor The Most Power Efficient Low Cost Solution specially design for PET Blowing.


  • Combined 2nd & 3rd stage design eliminates sealing against 40 bar, 3rd stage piston rod packing assembly and few valves for 2nd & 3rd stage.

  • Low RPM & rugged cast iron design ideal for heavy duty continues 24x7 operating year after year.

  • Forged crank shaft & connecting rod, precision main & crank pin bearings with force feed lubrication have very high load bearing capacity & hardly needs replacements.

  • Two throw balance-opposed frame, design to minimize unbalanced forces.

  • Cylinders constructed with large cast in-water jackets & specially designed intercoolers for dimensional stability & better cooling under continues operation.

  • Distance Pieces feature two compartments ensuring the lubricant isolated from the cylinders.

  • All components constructed in accordance with international standards.

  • PFC PETCOMP package comes with built in single point water inlet / outlet

  •  connection and air outlet connection. It requires very little time and labour during installation

Control Panel

Control Panel
Advanced micro processor based control system ensure trouble free operation, multi compressor control, online pressure, temperature & current display with built-in warning & shutdown function protect the compressor. It helps to plan maintenance intervention well in advance as it gives prior indications of service requirements.

In-Built Energy Saving Variable Frequency Drives (VFD)


Smooth Start-Up

The VFD is soft starting which allows for controlled acceleration and deceleration this result in reduced stress on mechanical components and enhanced system reliability which extend the life of the the compressor.

Lower Cost of ownership

Energy is the single largest cost in owning in air compressor with variable speed operation you will experience significant savings on this cost over the entire life of your compressor.

VFD keeps desired line pressure constant, adjusting automatically according to system air consumption by varying motor speed, only consumes the energy needed to produce the compressed air required by the system, in fixed speed if a compressor operates on no load, energy is wasted while no work is performed. This saves up to 35% energy compared to conventional cycling.

A fixed speed compressor operates on a load-unload band of at least 10 PSI around the working pressure, whereas with VFD Compressor can be operated within a band of 2 PSI since the compressor is not operated under higher than working pressure requirements, there is substantial energy saving. For every 2 PSI reduction in operating pressure, there is 1% power saving.
