Indicative Extraction Rates
The following table shows indicative extraction rates for the Flettner® TCX-2™ ventilator. It should be stressed that air extraction rates vary according to the positioning of the ventilator and the configuration of the vehicle or building to which the ventilator is fitted.
Wind Speed | Air Extraction Rate | ||
MPH | KM/h | cu ft / min | cu m / min |
10 20 30 40 50 60 70 |
16 32 48 64 80 96 112 |
18 37 58 81 102 126 149 |
0.52 1.05 1.64 2.28 2.89 3.56 4.21 |

The extraction rates above were measured in a wind tunnel by MIRA Ltd using a Flettner® TCX-2™ ventilator fitted to the roof of a Ford Transit van. The figures are provided purely for illustrative purposes as the extraction rates achieved are dependent upon the precise configuration of each application.
It is the responsibility of the fitter and the customer to establish the amount of air extraction that is required for each application, and to ensure that the positioning and the number of ventilators fitted are suitable.
The performance of the Flettner® TCX-2™ will be impaired if it is fitted to a sealed vehicle compartment or to a building with no independent air inlet. In such circumstances an air inlet such as a grille should be fitted in addition to the Flettner® TCX-2™ in order to provide an adequate path for air extraction to occur.
Maximum Temperature
The Flettner® TCX-2™ should not be used in temperatures that exceed 200°F (95°C).
