BlowerDoor SwemaAir 40

The robust thermo-anemometer for reliable leakage tracking on the building site!

Use the handy SwemaAir 40 to locate leakage in the building envelope at depressurisation during the BlowerDoor test. Sweep all connections, joints, and penetrations with the telescopic probe of the SwemaAir 40. Thanks to its increased sampling rate of 4/sec to be better able to track leakage, the temperature and air speed meter SwemaAir 40 will immediately show you even the slightest air flows. The shortened tip of the telescopic probe even in the corners of a room enables you to locate leaks easily. The display shows the result of the measurement in m/sec. There are two measuring ranges available for the exact measurement of the airflow.
The straight probe can be extended up to 66 cm. It can be attached to the SwemaAir 40 as desired, so that the device can be operated with one hand only. The sturdy casing of anodised aluminium with rubber-coated front ends is particularly impact-resistant and is gentle on sensitive materials.
