Minneapolis BlowerDoor The market-leading airtightness measuring system
From clean rooms to high-rise buildings: With two fan sizes and the ability to combine multiple systems, the Minneapolis BlowerDoor is predestined for measuring airtightness in all building types and sizes.
The measurement systems are characterized by outstanding accuracy and durability. The BlowerDoor test for quality assurance is software-based, as is the measurement according to ISO 9972. Optionally, a semi-automatic or manual BlowerDoor measurement can be performed.
With specific add-on components, Minneapolis BlowerDoor measuring systems are also successfully used to solve other tasks.
Proven add-ons are, for example, the determination of extinguishing gas holding times with the BlowerDoor FireProtection software, the leakage testing of ventilation ducts and the component testing with the Minneapolis Micro Leakage Meter, Bau.Tools BlowerDoor for the all-season sequential analysis by means of BlowerDoor and thermography as well as testing the air permeability of windows with the Window and Door Measurement System.
With the new TECTITE Express 5.1 software you can conduct highly accurate automated, semi-automated and manual BlowerDoor tests in accordance with ISO 9972 and EN 13829. The TECLOG Software is ideal for the use in large buildings as well as for the measurment with the Micro Leakage Meter, the FlowBlaster, and the Window and Door Measuring System.
In addition to the very high quality factory calibration, BlowerDoor GmbH also offers calibrations with DAkkS certificate for the pressure gauges and BlowerDoor measuring fans on accredited test benches. The extensive investments in accreditations were made in order to meet the increasing requirements of national and international standards. Part of our calibrations is an extensive functional test as well as the adjustment of the pressure measuring devices.
(Note: Laboratory accredited by DAkkS according to DIN EN ISO/IEC 17025:2018. The accreditation is only valid for the scope of accreditation listed in the annex to the certificate D-K-19788-01-00.)

Please note: The rental prices quoted are for one BlowerDoor measurement within 7 days. A prolongation for a surcharge is possible and need an agreement, please contact us!
Functional test and adjustment included.
In the calibration of the pressure gauge DG-1000 according to procedure A, we calibrate a minimum of 15 points in a measuring range of ± 2,450 Pa. If requested by the client, we can measure more points. The calibration cycle is repeated four times.Our calibration with DAkkS-certificate is conducted according to a standard defined by the German accreditation body (DAkkS). The national metrology institute, Physikalisch-Technische Bundesanstalt (PTB), provides the national standards indicated with the highest possible accuracy. The maintenance of the testing devices, the calibration process, and the organization of the lab are accredited according to German and European Industrial Standard DIN EN 17025. Like all DAkkS-accredited labs, our calibration lab is tested by an internal audit and by DAkkS at regular intervals.
Functional test and adjustment included.
The accuracy of our digital pressure gauge DG-1000 is ± 0.9 %. The working standards applied by BlowerDoor are based on national and international standards. For each differential pressure channel, we calibrate 20 measuring values in the range from ± 2,450 Pa. At BlowerDoor GmbH, the incoming calibration is followed by the adjustment of the pressure gauge so that deviation errors can be corrected as necessary. The outgoing calibration documents the optimized measuring accuracy of the adjusted pressure gauge. The preceding functional test also checks the tightness of the pressure sensors, the control of the BlowerDoor fan, and the overlay.
Recommended calibration interval: 2 years.
