An air purification system capable of removing substantially quantitatively commonly occurring gaseous liquid and solid contaminants, including water and hydrocarbons, from compressed air, thereby ensuring hydrocarbon-free moisture-free and particulate-and microbial-solid-contaminant-free compressed

An air purification system capable of removing substantially quantitatively commonly occurring gaseous liquid and solid contaminants, including water and hydrocarbons, from compressed air, thereby ensuring hydrocarbon-free moisture-free and particulate-and microbial-solid-contaminant-free compressed air, ready for application in pharmaceutical uses, comprising, in combination, and in the sequence indicated: p1 (1) a coalescer filter separating and removing hydrocarbon droplets and water droplets; (2) an adsorbent dryer sorbing water vapor and hydrocarbon aerosols at least in part on particulate desiccant; (3) an oil vapor adsorber sorbing hydrocarbon vapor and hydrocarbon aerosols at least in part on particulate activated sorbent; (4) an after-filter separating and removing particulate solids larger than bacterial dimensions; and (5) a bacterial-retentive final filter separating and removing particulate solids of bacterial dimensions and any remaining hydrocarbon aerosols. A air compressor and purification system capable of delivering hydrocarbon-free moisture-free and particulate- and microbial-solid-contaminant-free compressed air, ready for application in pharmaceutical uses, comprising, in combination, and in the sequence indicated: (1) an air compressor; (2) an after-cooler; (3) a compressed air receiver; (4) a coalescer filter separating and removing hydrocarbon droplets and water droplets; (5) an adsorbent dryer sorbing water vapor and hydrocarbon aerosols at least in part on particulate desiccant; (6) an oil vapor adsorber sorbing hydrocarbon vapor and hydrocarbon aerosols at least in part on particulate activated sorbent; (7) an after-filter separating and removing particulate solids larger than bacterial dimensions; and (8) a bacterial-retentive final filter separating and removing particulate solids of bacterial dimensions and any remaining hydrocarbon aerosols.
