When compressed air purity in accordance with ISO8573-1 Class 0 or Class 1 for total oil is required, Parker's carbon adsorbers are an essential component in a compressed air treatment system. They provide ‘Technically Oil Free Compressed Air’ from either oil free or oil lubricated compressors. Oil free plant air can be affected by many factors such as pressure, temperature, air flow, oil concentration and humidity. Correct carbon adsorber selection considers all of these factors to ensure consistent outlet air quality over 12 months of continuous operation.
