The Airex Emergency Isolation Unit, when adapted to the Mobile Self-Contained Air Filtration System, supplies the medical emergency team with either a positive pressurized isolation chamber (shown) or a negative pressurized isolation chamber, in just minutes. 70 air changes per hour using either HEPA (99.997 percent at greater than 0.3 micron) or ULPA (99.9995 percent at 0.07 micron) filtration, guarantees the maximum isolation for contagious or hazardous biologically impacted patients or for patients who must be protected from pathogens that would impact their health or for patients who require a pure environment to recover from respiratory distress, excessive smoke inhalation or hyper-sensitive reaction to irritants or allergens. This system, with its mobility and flexibility, is the ideal, low cost, and quick response patient isolation solution for Emergency Medical professionals.
