Ingersoll Rand Awarded Class 0 Certification for Entire Reciprocating Oil-Free Compressor Portfolio

Date: Nov 29, 2016


DAVIDSON, N.C., Nov. 29, 2016Ingersoll Rand®, a global leader in compression technologies and services, recently earned ISO 8573-1 Class 0 certification on all of its PETStar® reciprocating compressors. This latest certification expands the collection of Ingersoll Rand Class 0 certified technologies, which already consists of air- and water-cooled, oil-free rotary screw compressors and water-cooled oil-free centrifugal compressors.

For high-pressure applications such as the manufacturing of polyethylene terephthalate (PET) bottles for food and beverage, pharmaceuticals, electronics and many other critical applications, Class 0 certification eliminates the risk of air contamination that can result in damaged products and significant losses in revenue and customer trust.

“To ensure high-quality manufacturing standards, customers want the peace of mind of 100 percent oil-free air that comes with Class 0 certification,” says Eric Seidel, vice president of product management for compression technologies and services at Ingersoll Rand. “With this latest certification for PETStar, Ingersoll Rand now offers a full portfolio of reciprocating oil-free technology that guarantees pure air while reducing waste, inefficiencies and environmental footprint.”

The PETstar Series from Ingersoll Rand was awarded ISO 8573-1 Class 0 certification after undergoing rigorous testing by TÜV Rheinland® – a global leader in independent testing and assessment services. The PETstar 4 (PS4) line from Ingersoll Rand includes nine, four-stage models that deliver between 250 kW and 525 kW of air power. The PETstar 3 (PS3) range sold in some geographies, like India and Asia Pacific, were also tested and certified. Built with industrial grade components and double-acting cast iron cylinders, these compressors provide high durability. Low speeds and rugged construction gives ideal maintenance and lifecycle costs. 

By generating pure air, free from additional contaminants, Ingersoll Rand oil-free compressors also minimize downtime associated with cleaning filters and other air system components. Reduced levels of contaminants also help air system components last longer and ensure higher overall product quality.

The Class 0 certification was created in 2001 in response to industry needs for oil-free air. The most stringent air quality class, Class 0 certification guarantees that a compressor discharges air free of added oil aerosols, vapors, and liquids. Ingersoll Rand has held this prestigious certification on both its oil-free centrifugal and rotary screw air compressor technologies since 2007.
