Zero Air generator

The AirGen series KZA FID Air is able to remove the total hydrocarbons to less than 0.05 ppm from the external compressed Air. Very compact, the KZA FID Air can purify up to 15 L/min of compressed Air and can bear a pressure up to 7 bar (101 PSI). The filtration of the hydrocarbons is performed by using a catalytic oven filled with palladium.

The reduction of hydrocarbons, including methane, and carbon monoxide decrease the background noise level and gives much better baseline stability, considerably increasing detector sensitivity and ensuring precise analytical results. High efficiency coalescing pre-filtration and post filtration of particulate size greater than 0.01 microns are used to prevent any kind of particles from entering the analytical device.

The KZA FID Air has a very simple and efficient interface. It can also be managed by the Hydrogen  series KUBE is ideal to supply Hydrocarbon free Air to FID detectors.
