The ZA7000 produces 7 LPM of ultra-high-purity zero air with contaminant levels below 0.5 ppb for SO₂, H₂S, NO, NO₂, NH₃, and hydrocarbons, and below 1 ppb for O₃ and CO. Designed for lab-grade reliability, it supports gas chromatography, emissions testing, and air monitoring while eliminating the need for heavy, hazardous zero air cylinders. An integrated CO₂ scrubbing system maintains CO₂ levels below 1 ppm for stable baselines in FID and emissions applications. A precision-controlled catalyst ensures thermal stability and delivers ultra-clean air with a −100°F (−73°C) dew point. Housed in a compact, low-noise 14" × 13.5" × 6.61" chassis weighing just 26 lbs, the ZA7000 fits seamlessly into benchtop or wall-mounted setups. Its modular design, standard 1/4" NPT connections, and 120V or 220V power options make it a versatile, scalable zero air solution for space-constrained laboratories requiring consistent, ultra-pure air.
