NEW: Manufacturer's fan calibration (1-point) for BlowerDoor MiniFan!

New at BlowerDoor is the manufacturer's calibration (1-point) according to manufacturer's specification for the measuring fan BlowerDoor Standard (model 4) and BlowerDoor MiniFan (model DuctBlaster). One measured value is calibrated per measuring ring. The requirement of ISO 9972 for the accuracy of the measuring systems of ± 7 % is assessed.

A previous basic maintenance and functional test is included. We calibrate according to date request and ask for registration, in order to ensure short calibration times of max. 5 working days.

BlowerDoor & Thermography

Thermography is an imaging method for visualizing the surface temperature of objects. Energetic problem areas, leaks under plaster and moisture become visible non-destructively by means of thermal imaging. Therefore, thermography is ideal for visualizing and documenting leaks, especially in very large or very high buildings.

If the thermogram is generated at differential pressure (negative pressure) with the BlowerDoor measurement system, even more informative thermal images are usually produced, as the air flows can be very well displayed and evaluated in the thermogram.

Measurement Technology for Airtightness: The Competence of BlowerDoor GmbH

Minneapolis BlowerDoor measuring systems are market leaders in Germany today and are among the most successful air tightness measuring devices worldwide. With a measuring range of 5 - 2,300 m³/h to 19 - 7,200 m³/h and the ability to combine several BlowerDoor systems, the Minneapolis BlowerDoor is universally applicable.

The outstanding precision and durability of our measuring instruments as well as the transparency of the measuring process underline the high quality of the BlowerDoor measuring system. In addition to qualified consulting and the sale of state-of-the-art measurement technology for airtightness, the calibration of the measurement systems, a comprehensive range of seminars and the continuous further development of hardware and software are services from which our customers benefit.
