A quick tool for your convenience

For all you designers, technicians and engineers, or whoever needs it, we provide our immediate calculator for the dimensioning of ducts. Simply select the data shown below and then, by opening the diameter selection menu, the most suitable diameter will automatically appear for you to choose from. The colour of the scale that appears indicates the suitability of the diameter in relation to the speed obtained from the data entered and which you can see in the field below. The first diameter that appears in green is usually the best one to choose while diameters in red indicate unacceptable diameters.

An effective and precise tool for a first dimensioning of DHI diffusers in total autonomy! By using the link below you can access the program which is therefore useful for a preliminary design phase. The OneAir technical department is available to customers and designers for further information and support for the final sizing of our ducts.
