fan model 4 and model 3. Extensive fan check included.

The calibrations are conducted by an accredited lab and based on their traceability to national standards (EN 17025) provide maximum accuracy. Per flow-ring (open fan and rings A - E), the calibration includes testing three values each in the lower, mid-level and upper flow-rate measuring range in a chamber test stand at a pressure differential of 50 Pa.

We calibrate all BlowerDoor measuring fans using a test stand designed and implemented by BlowerDoor GmbH, which has been calibrated by the Physikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute, with an accuracy of ± 1%. This level of accuracy is necessary in order to attest conformity of the measuring fan of up to ± 4%. The calibration stand has been accredited by DAkkS (Deutsche Akkreditierungsstelle GmbH) in August 2017.

Calibration interval referred to manufacturer’'s recommendations: 4 years.

Please note: Calibration is conducted once every month in the first week of each month. Your binding registration for calibration must have been received by the 15th of the month preceding the calibration. Make sure to send your fan including all rings A - E!
