Due to the worldwide demand for ventilators increasing, we are receiving regular requests about ventilator supply. Fisher & Paykel Healthcare does not manufacture mechanical ventilators. We produce other respiratory support and humidification products, and associated consumables. For the latest updates on using our products to treat patients with COVID‑19, visit our COVID-19 Resource Center.
Evaqua is the world’s first breathing circuit technology that minimizes mobile condensate in the expiratory limb by allowing water vapor to diffuse through the tubing wall.
Advanced ventilator breathing circuits that provide exceptional performance in an easy-to-use system, helping increase the effectiveness of patient care and reducing the amount of intervention required.

Less condensate due to insulating MicroCells
Protection by protecting the circuit from cool drafts
MicroCells form an insulation shield between the cool air outside and the water vapor inside.
Less condensate with permeable Evaqua technology
Protection through a robust MicroCell wall structure
Allows humidity to diffuse out of the breathing circuit freely. As Evaqua is only permeable to water vapor, it maintains a gas seal and reduces the opportunity for pathogen transfer.
Breaking open a breathing circuit (to drain condensate, change circuits etc.) introduces the potentially hazardous effect of a drop in PEEP. Zero PEEP has been associated with the leak of infectious secretions past ET tube cuffs, due to circuit pressure changes, regardless of cuff material or inflation pressure.
