Calibration of BlowerDoor Fans

We offer a calibration with DAkkS certificate for the measuring fans BlowerDoor Standard (model 4 and model 3) as well as BlowerDoor MiniFan (model DuctBlaster) on our test stand calibrated by the Physikalisch-Technische Bundesanstalt. For each measuring ring (open fan as well as ring A - E or 1 - 4) three measured values are calibrated. The measuring accuracy of the BlowerDoor measuring fans of ± 4 % (open fan as well as rings A - C or 1 - 4) and ± 5 % (rings D and E) is assessed. You will receive a DAkkS certificate.

The previous basic maintenance and functional test is included. We calibrate according to monthly calibration dates. Registration is required.
