Parker Balston Analytical Gas System - Zero Air Generator
Model 75-83-220-M312
The Parker Balston 75-83 Zero Air Generator is an engineered system which will replace inconvenient high pressure gas cylinders as a source of hydrocarbon-free air. The 75-83 will purify on-site compressed air to a total hydrocarbon concentration of less than 0.1 ppm (measured as methane). The Zero Air Generator may be used to generate fuel air for Flame Ionization Detectors (FID’s) or for a zero reference for any instruments which measure hydrocarbon concentration. The 75-83 is capable of producing up to 1000 cc/min of zero grade air and will serve up to three FID's.
