AS80 Zero air generator

The AS80 Zero air generator is designed to provide an inexpensive source of clean, zero-grade air for flame ionisation detectors (FID). The unit removes all hydrocarbons, including methane, down to 0.1% of original  level. Up to 10 FID units can be run from one unit. The AS80 contains a high temperature furnace containing alumina pellets coated  in platinum, this oxidizes all combustible compounds to CO2 and H2O. The unit can completely remove methane at rates of up to 5 l/min high efficiency and up to 20 l/min medium efficiency.
