ZA TOTAL

Zero Air generator

The AirGen series ZA-TOTAL is able to remove the total hydrocarbons to less than 0.05 ppm from the external compressed Air. It is also able to remove other pollutant like Humidity, CO2, CO, NOx, SO2 and Hydrocarbons. Very small in size, the ZA-TOTAL can filter up to 30 L/min of compressed Air and can withstand a pressure up to 8 bar (115 PSI). 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. The hydrocarbons and CO are removed with a catalytic oven filled with palladium, the Humidity and CO2 is removed with a dual molecular sieve PSA system, NO is removed with Purafil and other components are removed with an active charcoal filter.

Stackable with HG PRO/ HG BASIC
