The ALF 150 is lightweight, compact & totally self contained testing unit. It develops static pressure 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 & up to 70 L/s for Class C/D leakage tests.

The ALF 150 is designed with 3 rapid change ( push in – pull out ) Conical inlet nozzles designed to ISO5801:2007. The use of Conical inlet

nozzles makes The ALF 150 a primary measuring device.

The ALF 150 comes with a single all in one instrument panel making this duct leakage tester easy to use and configure through the intuitive

menu driven interface. The instrument panel also provides an SD card facility & USB data output. A flexi-hose with pre connected sleeve coupling,

duct adapter & static pressure tubing is included in the carrying case so that the ALF 150 is ready to use from the moment it is unpacked.
