BLOWERDOOR GMBH - MessSysteme für Luftdichtheit

Minneapolis BlowerDoor is a modular measuring system for airtightness. 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.

With a measuring range of 5 to 2,300 m³/h, our compact BlowerDoor MiniFan System is perfect for use in individual apartments or very airtight or smaller buildings.With the new DG-1000 high precision pressure gauge and the TECTITE Express 5.1 software included in the package, you can conduct highly accurate automated, semi-automated or manual BlowerDoor tests in accordance with ISO 9972 and European Standard EN 13829.

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.

The Minneapolis Micro Leakage Meter (MLM) Measuring System has been developed by the manufacturer The Energy Conservatory in close cooperation with BlowerDoor GmbH in order to guarantee the functionality of ventilation systems by conducting airtightness tests of the duct system. With a measuring range of 0.17 to 78.5 m³/h, the MLM is also suitable for testing building components as well as small and highly airtight clean rooms.

With a measuring range of 17 to 500 m³/h, the Minneapolis FlowBlaster has been especially designed for testing ventilation systems during residential and commercial construction. In combination with the measuring fan BlowerDoor MiniFan, it allows the precise measurement of the air flow at supply and exhaust air valves. Measuring the supply and exhaust air flow at the respective valves provides information as to whether the requirements have been implemented as designed. If the air flows measured at the valves deviate from the requirements, the ventilation system can be adjusted.

The airtightness of outside windows and doors is an important criterion for achieving an airtight building envelope. The Window and Door Measurement System developed by BlowerDoor GmbH allows you to determine the joint permeability of building components in a simple and accurate way. On the basis of the measurement results windows and doors can be classified in accordance with EN 12207 (windows and doors, air permeability-classification).

Bau.Tools BlowerDoor software has a new upgrade, offering professional thermographers even more: The differential thermography has been expanded to include sequential analysis, while the user interface has been newly designed at the same time to provide easy and intuitive usability. Bau.Tools BlowerDoor is now avalaible in English, German and French.

Fire safety is one of the areas where the use of BlowerDoor measurements is increasingly gaining in importance. In general, it is server rooms that are measured, where in the case of fire, this is quenched by special extinction gases. High-quality technology can thus be protected against damage from sprinkling or fire water. A prerequisite for the fire protection through extinction gases is an airtight room envelope.With the Minneapolis BlowerDoor measuring system and the FireProtection software, you can easily and accurately determine extinction gas holding times in accordance with ISO 14520 in rooms of angular volume.

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.
