Maintain the high accuracy of your BlowerDoor measuring technology by regularly submitting it to a calibration. Benefit from the high accuracy of the BlowerDoor measuring technology: At ± 4% or rather ± 5% (flow rings D + E), the accuracy of the BlowerDoor testing flow rings – as well as that of the pressure gauge DG-700 (± 1%) or DG-1000 (± 0.9 %) – clearly exceed the minimum legal requirements. The manufacturer’s calibration as well as the calibration with DAkkS-certificate, are subject to the highest quality standards. When calibrated, all measuring systems undergo a preceding functional test. If required, we will gladly provide you with a replacement device at favorable rates and conditions, while your BlowerDoor measuring system is being calibrated or repaired.

To conduct airtightness tests in large buildings, simply combine several BlowerDoor fans (BlowerDoor MultipleFan): With up to three fans per door opening, Germany’s leading measuring system for airtightness easily masters even large air-flow rates! The BlowerDoor MultipleFan system consists of three BlowerDoor fans and two digital DG-1000 pressure gauges, and was developed for airtightness measurements of large buildings with an envelope area of approximately 7,000 to 36,000 m² or an internal volume of up to 440,000 m³. As a modular system, the MultipleFan system can be used for testing larger industrial and administrative buildings, but also for single-family homes and apartment buildings using one or two BlowerDoor fans.
