All Carcoon ‘protective airflow systems’ including the Traditional ‘EVO’ Veloce, BikeBubble, JetCell and HeliCell, all use Carcoons patented triple filtered Active Airflow. Active Airflow is a unique system exclusively used and developed by Carcoon to allow continual interior air circulation whilst most importantly improving air quality via Activated Carbon filters used under super atmospheric pressure. The advantages of Active Airflow are several, however the important advantages are reduced ambient flow (most important) and reduced odors such as oil and fuel vapors and contaminates from within the exhaust system. Air movement within the storage environment also helps eliminate dead (still) air pockets within the protective environment even in all those shielded places in and around the vehicle.
