Minneapolis BlowerDoor is a modular measuring system. With its measuring range from 19 m³/h to 7,200 m³/h and the possibility to combine several BlowerDoor systems (MultipleFan), there are no limits to its use in Passive Houses, in newly constructed buildings, and in existing buildings and apartment buildings, as well as in industrial and administrative buildings. With the innovative DG-1000 high precision pressure gauge and 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 the European Standard EN 13829 via a laptop computer. When performing quality assurance tests, the BlowerDoor fan is controlled directly from the DG-1000 and a one-point test (without a laptop) is conducted to detect leakages.
