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.
FEATURES :
- 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
- Less day-to-daymaintenancecanbeusedaspenetrationandFIDgasfurnacecleaninggascanwithan external air compressor unattended automatic drainage function
The Zero Air Unit is a precision gas generator that produces clean, hydrocarbon-free zero air to calibrate air quality analyzers and gas monitoring instruments.
Zero air ensures that gas analyzers are calibrated against a baseline free of contaminants, improving accuracy and compliance with air quality standards.
It’s ideal for calibrating SO₂, NOx, O₃, CO, and other ambient gas analyzers used in environmental monitoring stations.
Yes — it’s designed for both laboratory and field calibration applications, offering reliable zero air wherever needed.
By supplying consistent zero-contaminant air, it helps eliminate baseline drift and ensures precise span/zero calibration of air quality sensors.
