Compressed Air Quality, Measurement Achievement.pptVIP

Parker is On Compressed Air Quality, Measurement Achievement Compressed Air Quality - Measurement Achievement C.A.G.I. (Compressed Air and Gas Institute) Pneurop (European Compressed Gas Institute) ISO Standards for Compressed Air Quality 1. How is Compressed Air Quality Measured? 2. How can the ISO Standards be achieved? Contaminants in Compressed Air 1. Particulate 2. Vapor 3. Liquids Effects of Air Contaminants Plug orifices and block clearances between moving parts Erode surfaces, wear out seals, and increase leakage Foul heat transfer surfaces Reduces adsorptive capacity of desiccant used in compressed air dryers Lower efficiency in pneumatically operated equipment, such as air tools and valves Reduced system performance and an increase energy consumption Effect of Air Contaminants The Nature of our Environment 1. Particulates: pipe scale / rust rocks pollen yeast cells airborne carbon mold welding flash penicillin Contaminants 80% of the Contaminants in a Compressed Air System are: 2 micron or smaller in size! Particulate Filter/Element The Nature of our Environment 2. Vapors: water vapor oil vapors paint vapors volatile solvent vapors Size Distribution - Vapors Adsorber Filter/Element The Nature of our Environment 3. Liquids: Aerosols (Basic Concepts) Dust Disintegration of solid, Nature, wind Pollen, road dispersion of powder Human activity dust, fly ash Fog Condensation from Heating/Cooling Atmospheric cloud and fog Mist Atomization Atomizer, nebulizer, Sulfuric acid condensation ultrasonics, mist, insecticide spray Smoke Vaporization/ Combustion, flame Cigarette condensation smoke, soot, diesel exhaust Smog Photochemistry Sun light Urban smog Liquid Content A lubricated 25 H.P. compressor (100 scfm) with a 35 ppm carryover will pass about 2 oz. of oil every 8 hours Oil Carryover by Compressor Type Coalescing Filter/Element Borosili
