Flettner 2000™ Ventilator on BT Openreach Van

As the snow falls, the Flettner 2000™ Ventilator continues to spin on this stationary BT Openreach van. Our vents continue to work when the vehicle is not moving to extract unwanted contaminants and manage the internal environment of the vehicle.
We hope this BT engineer fixed the problem quickly to escape the cold.
