Aerogen

Aerogen is a privately held, commercial-stage medical device company and a recognized global leader in aerosol drug delivery for acute respiratory care. Founded in 1997 and headquartered in Galway, Ireland, the company has built its business around a patented vibrating mesh nebulizer technology, which it integrates into its own product lines and partners with leading ventilator manufacturers. Its devices, such as the Aerogen Solo and Aerogen Ultra, are used across invasive mechanical ventilation, non-invasive ventilation, high-flow, and self-ventilating therapies, supported by a substantial body of clinical evidence. The company operates in a large and growing market driven by respiratory diseases and critical care needs.

Proprietary vibrating mesh nebulizer technology featuring a 5mm aperture plate vibrating at 128,000 Hz to produce a consistent 1-5 µm aerosol for efficient lung drug delivery.

Aerogen competes with other nebulizer manufacturers like Vyaire Medical, Philips (Respironics), Omron, and PARI GmbH. Its key differentiator is its focused, high-performance vibrating mesh technology for the acute care hospital setting, where it has established strong clinical validation and OEM partnerships that create barriers to entry.
