ETC Oil-Free Converter

Class 0 Oil-Free Air


  • Guarantees oil-free compressed air according to ISO 8573 Class 0
  • Achieves class 1 even with hydrocarbon concentrations of up to 154,000 parts per billion at the ETC inlet.
  • Clean condensate with a hydrocarbon concentration downstream of the ETC
  • Compared to many oil-free compressors, the condensate is not acidic but neutral, with a ph between 6 and 7.
  • Independent of the ambient air quality, compared to oil-free compressors.
  • Minimizes bacteria, fungus and microbial content in the compressed air.
  • 20,000 working hours or 30 months warranty on the catalytic function.
  • Compatible with variable speed drive compressors operating between 110% and 20%.
  • Converts silicone monomers to silica and absorbs the silica.
  • Compact design with improved insulation and reduced energy consumption.
  • Electronic control unit & reduced number of electrical wear parts.
  • Pressure drop over ETC system approximately 5.8 psi at 100 psi.
  • Absolutely secure system with a protective shutdown unit that prevents oil-containing compressed air from entering the network in the event of malfunction.

The ETC Catalytic Converter ensures the delivery of oil-free compressed air for critical applications where air purity is essential.

The proprietary catalytic air treatment process actively oxidizes hydrocarbons into water, carbon dioxide and nitrogen, providing class 0 oil-free compressed air, according to Compressed Air Quality Standard 8573-1.

Ideal for the pharmaceutical, food & beverage, biotechnology, electronics industries, and any other industry required to fulfill stringent compressed air quality standards.

Why is an ETC Catalytic Converter Critical?

Air quality is a critical concern for many sensitive applications, such as the pharmaceutical, food and biotechnology industries, which require class 0 oil-free compressed air, according to compressed air quality standard ISO 8573-1.

Typical oil-free compressors do not remove oils suspended in ambient air, and consequently do not actually provide oil-free air. Conversely, the ETC Catalytic Converter acts independently of ambient air quality, guaranteeing the provision of class 0 oil-free compressed air in all applications.
