Krueger’s new reverse-flow fan filter unit is the perfect choice for hospital isolation rooms housing patients suffering from highly contagious diseases. It works by creating a negative pressure environment that removes air from an isolation room, cleans it via the unit’s built-in HEPA filter, and keeps airborne contaminants from escaping back into the room. The unit can be mounted in the ceiling or provided as a rolling mobile version. The mobile unit includes built-in, heavy-duty swivel casters with brakes, allowing it to be moved easily from location to location as the facility requires.
