For the determination of the leakage we will use our air tightness testing device MEZ-DUCT-TESTER 216. This easy to use and cost-effective tool enables you to determine the current leakage of the air duct as well as the air tightness class attained according to EN 13779EN 1507EN 12337 & EN 12599.



Our MEZ-DUCT-TESTER 216 is fully equipped for the use on constructions sites and can be transported anywhere in its robust plastic case. Furthermore, the testing device has a powerful fan, which allows you to test bigger leaks and surfaces. The air tightness testing device is integrated in a robust plastic case and all connections are on top or on the side. All necessary hoses and accessories are kept inside a second plastic case.
