Measuring fan

For accurate ventilation you must be able to measure exactly.
In the development of the propeller, emphasis has been given to aerodynamics and bearings. The propeller runs at minimum air flow and the bearings are standard in stainless steel. The aerodynamic shape of the propeller also ensures that as little resistance as possible is created. The measuring fan is direction-sensitive and by means of LED indication is visible if it goes right or wrong. Using the quick click clamps, the measuring fan can easily be mounted in any tube. The measuring fan is available in various standard sizes. Different sizes are available as desired.
With larger numbers you can also choose your own color.
