PET Reciprocating Air Compressors
Ingersoll Rand PETStar® 4 reciprocating air compressors are designed to deliver exceptional durability, reliability, and energy efficiency for PET applications. While conventional PET reciprocating compressors typically use three-stage compression, the PETStar® 4 utilizes an advanced four-stage compression system to achieve improved efficiency and optimized energy consumption.
Built with industrial-grade components and double-acting cast iron cylinders, PETStar® 4 compressors are engineered for long-term, dependable performance. Their robust construction helps reduce maintenance requirements, minimize operating costs, and lower overall lifecycle expenses.
Key Features
- Three-step capacity control (0%–50%–100%) helps match compressor output with changing air demand, optimizing energy consumption.
- Advanced Xe-Series compressor controller continuously monitors critical operating parameters to support efficient and reliable compressor performance.
- IP55 TEFC motor with star-delta starter provides energy-efficient motor starting and reliable operation.
- 100% oil-free, non-lubricated, water-cooled design delivers clean compressed air for demanding PET applications.
- Four-stage balanced, opposed configuration helps minimize vibration and ensures smooth, stable operation.
- Double-acting pistons with heavy-duty Class 40 cast iron cylinders provide excellent durability and extended service life.
- Piston rings and packing rated for up to 16,000 hours help extend maintenance intervals and reduce operating costs.
- Optional protective features, including rod-drop position wear indicators, provide additional monitoring and help identify potential component wear.
