What AirSep Corp. does

AirSep Corp., founded in 1987 and headquartered in Amherst, United States, is a manufacturer of on-site oxygen and nitrogen gas generation systems serving medical, industrial, and commercial customers globally. The company operates as the commercial/industrial division of CAIRE Inc., which is itself a subsidiary of Niterra (a Japanese industrial gases company). AirSep employs between 501 and 1,000 people and sells its products through direct sales channels via CAIRE Inc.'s commercial division.

The company's core technology is Pressure Swing Adsorption (PSA), including Vacuum Pressure Swing Adsorption (VPSA) for high-capacity applications. Its product portfolio spans two main categories. Oxygen products include Self-Contained O2 Generators, Mini-Pack O2 Generators, Standard O2 Generators, Packaged O2 Systems, O2 Cylinder Refilling Systems (including the FDA 510(k)-cleared Centrox-CR station launched in May 2025), and VPSA O2 Tonnage Plants for large-scale industrial use. Nitrogen products include Twin Tower PSA Nitrogen Gas Generators, Modular PSA Nitrogen Gas Generators, and the new N2WAVE PSA Twin Tower and Modular Series. Applications span hospitals and medical facilities, ozone generation, aquaculture, oxygen lancing/decarburization, wastewater treatment, gold leaching, food and beverage processing, oil and gas, pharmaceutical manufacturing, and mining/mineral processing.

AirSep generates revenue through direct hardware sales of its gas generation equipment, with no public pricing disclosed. Sales are conducted via phone support and a request-a-call contact mechanism. The company's value proposition centers on enabling customers to generate oxygen or nitrogen on-site, eliminating dependency on cylinder deliveries and recurring rental charges. Key competitive differentiators include FDA 510(k) clearance for medical applications, proprietary PSA technology, and a portfolio covering everything from portable units to industrial-scale tonnage plants.
