The Compact Air Plus is a new generation of intelligent powered air-purifying respiratory system from North. The Compact Air Plus has been improved in comparison with the original Compact air. The compact unit houses a small and powerful NiMH battery. The unit is supplied as standard with a comfort support belt that distributes the weight evenly. The Compact Air Plus is easy to use and maintain. When battery power is low and/or the airflow is beneath a safe level, the electronic alarm system does not only warn you acoustically, but will also alarm you optically. With assistance of a new energy saving motor management system, the Compact Air plus guarantees a prolonged constant and safe airflow.
