Zero Air Unit

Zero gas unit to provide clean,dryzero-air equipment.Mainly used forambient air quality monitoringsystem  and the zero calibration of the instrument, it can also be used as penetration tube furnace cleaninggas or supporting gas equipped with FID analyzer   

Zero gas unit comprises an external oil -free aircompressors, pressure and flow controllers,waterremovalsystems,SO2,NO,NO2,O3 and H2S removal,and removal of COand hydrocarbons

Zero gas unit is based on principles such as  adsorption,filtration,reaction,except for SO2 in the air,NO2,03,H2S,CO,NH3,hydrocarbons and particulateoutput dry clean air

Equipment removal system moisture in the air can be removed, producing less than one 20T dewpoint ofthe air,not under the influence of inlet air dewpoint.Also contribute to the removal of othergases,greatlyprolongs the life ofchemical remover.



  • Using three-stagewatersystem,automaticwater,inadditiontostrongwaterwithlongterm SO2NO,NO2,03and H2S
  • Removing with high-efficiency removal of CO and hydrocarbon
  • Producedbydry, clean,stableflowandpressure
  • Maximum out put of zero flow of up 20L/min
  • Adjustable out put pressure is simple
