ALF150

The ALF 150 Duct Leakage Tester is a cost-effective, compact, and lightweight solution for testing ductwork systems for leakage under both positive and negative pressure. Designed for commissioning engineers, this fully self-contained unit includes everything necessary to perform tests. It can generate static pressures ranging from -2500Pa to +2500Pa, with flow rates between 1 and 150 l/s. The ALF 150 provides approximately 140 l/s for Class A leakage tests and up to 70 l/s for Class C/D tests.

ALF150+

The ALF150+ model offers greater accuracies with the inclusion of an ambient conditions module which will automatically measure the ambient temperature and barometric pressure for you. From these measurements, the real time air density will be calculated and used when calculating the leakage rate of the ductwork under test.
