Caire

What Caire does

CAIRE Inc. is a global manufacturer of medical and commercial oxygen delivery systems, headquartered in Ball Ground, Georgia, and operating as a wholly-owned subsidiary of Japanese conglomerate Niterra Co., Ltd. (formerly NGK Spark Plug) since 2018. The company serves three end-markets: patient oxygen therapy (portable and stationary oxygen concentrators such as FreeStyle Comfort, Eclipse 5, Companion 5, and NewLife Intensity, plus liquid oxygen systems under the HELiOS brand), clinical cardiorespiratory diagnostics (via the January 2023 MGC Diagnostics acquisition, including the Fenom Flo portable FeNO monitor), and industrial/commercial on-site gas generation (PSA and VPSA oxygen plants and nitrogen generators via the AirSep division). Core technology is rooted in Pressure Swing Adsorption and Vacuum Pressure Swing Adsorption gas separation, complemented by proprietary oxygen-delivery firmware including autoSAT, UltraSense, and autoDOSE that modulate oxygen bolus delivery to patient breath rate.

The business operates a hybrid go-to-market: direct enterprise sales to hospitals, government buyers, and industrial customers in seven core geographies (USA, Japan, China, Germany, Italy, Australia), augmented by authorized distributors such as Sunset Healthcare Solutions (Canada) and Chemonics International (humanitarian deployments), plus an authorized service network (e.g., Careica Health). Revenue is generated primarily through hardware sales of oxygen concentrators, diagnostic systems, and industrial gas generation equipment, supplemented by aftermarket service, parts, and accessories. Pricing is quote-based and not publicly disclosed, with multi-year contracts typical for institutional and government accounts. Customer reach spans 117+ countries, with 5,000+ AirSep hospital installations across approximately 50 countries, and recurring product launches in 2025-2026 (Centrox-CR, FreeStyle Comfort with autoSAT, Fenom Flo) suggest continued product-line momentum under Niterra's ownership.
