Benefit from the high quality measurement of the German market leader BlowerDoor: Synergies in engineering, product development and training have made the Minneapolis BlowerDoor one of the most succesful devices for air tightness measurements worldwide.

The BlowerDoor Multifan module consists of 3 BlowerDoor fans and 2 digital DG-700 pressure gauges, and was developed for air-tightness measurements for buildings with an envelope area of 7,000 to 36,000 m² (internal volume of the building of up to 40,000 to 450,000 m³). As a modular system, the Multifan set can be used for testing larger industrial and administrative buildings, but it is also suitable for two separat BlowerDoor-tests in family houses. >more<

In the following pages, we invite you to discover the versatility of the Minneapolis BlowerDoor for air tightness measurements in Passive Houses, newly constructed single-family homes, and in building rehabilitation.
