Gas chromatography compressed air purifier

3-Stage compressed air purifier for dry, hydrocarbon-free instrument air. Particulate and moisture removal to 0.01-micron and hydrocarbon vapor (>C4) removal to less than 1 ppm. Flow rates as high as 14 SCFM (400 lpm). Automatic float drains, pressure regulator and gauge are standard. Insures that any compressed air source will be instrument quality, without the ongoing cost and hazards of high-pressure gas cylinders.
