ALF 150 Duct Leakage Tester
The ALF 150 duct leakage tester is a light-weight and totally self-contained primary device machine. It can generate up to 150l/s of airflow and test up to 2500Pa static pressure.
The ALF 150 duct leakage tester is a light-weight and totally self-contained primary device machine. It can generate up to 150l/s of airflow and test up to 2500Pa static pressure.
It is capable of developing static pressures from -2500Pa to +2500Pa, and flow rates of 1 to 150l/s. This provides approximately 140l/s of air flow for Class A leakage tests and up to 70l/s for Class C/D leakage tests. The ALF 150 uses conical inlet nozzles, which means the unit is a primary device.
A single all in one instrument means that this duct leakage tester is not only simple to use but also removes the complexity that might be associated with operating a duct work leakage tester and other forms of testing equipment. The ALF 150 is easily transportable.
