The ventec Magnum series was designed with a new approach to tunnel ventilation, a Fully Varaible system.  Not a multiple staged system, but multiple magnums variating together. In this manner, the airflow constantly adapts to the animals' needs, avoiding over drafting in cooler climates where sudden changes in weather may occur.
