BlowerDoor Standard

Universal use: The Minneapolis BlowerDoor

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.

New: The digital pressure gauge DG-1000

The innovative DG-1000 convinces with its intuitive use, clear structure, and modern design. Its high-resolution touch screen and intelligent micro-processor provide you with the functions of a modern mini-computer. New requirements are constantly fed into the measuring software and users can install and run the latest firmware updates free of charge at any time. The high accuracy of the DG-1000 guarantees reliable measuring results at maximum precision.

The DG-1000 comes equipped with USB and Ethernet ports, as well as an integrated WiFi module. BlowerDoor measurements recording and evaluating a measuring series according to ISO 9972 or EN 13829, are conducted with the TECTITE Express 5.1 software. When performing quality assurance tests, you can search for leakages with the DG-1000 or the TEC Gauge App at a constant building pressure differential.  The DG-1000 is compatible with all presently existing and new BlowerDoor measuring systems and may also be purchased as an upgrade. According to the manufacturer’s indications, the calibration interval is 2 years.

State of the Art: The Airtight Building Envelope

The airtightness of the building envelope is an important prerequisite for realizing modern energy concepts in new buildings, as much as for construction projects on existing buildings. It is also an essential aspect of quality assurance. Leaks in the building envelope increase ventilation heat losses. If ventilation equipment is installed in a building, an airtight building envelope is necessary to ensure flawless functioning of the installations, as uncontrolled air flow in the building prevents the optimal use of heat recovery systems and interferes with fresh and exhaust air supply. Preventing drafts significantly increases the indoor  comfort level. Structural damage caused by convective moisture transport into the building construction can be avoided. When rehabilitating existing buildings, an air barrier can be implemented to achieve current low-energy or even passive-house standards.
