ALF 150 Duct Leakage Tester

The ALF150 is a low cost, compact, light-weight and totally self-contained testing unit. It develops 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 ALF150 is designed with three rapid change (push in – pull out) conical inlet nozzles designed to ISO5801:2007. The use of conical inlet nozzles makes the ALF150 a primary measuring device. The ALF150+ is the high-end version of the ALF150. It features ambient temperature and barometric/absolute pressure sensors for real-time compensation giving improved accuracy when measuring flow rates. It also features a PID test pressure control mode with data logging, providing a fully automatic test facility for increased productivity. Both the ALF150 and ALF150+ come with a single all in one instrument making this duct leakage tester easy to use and configure through the intuitive menu driven user interface. The instrument also provides an SD Card facility and USB data output. A Flexi-Hose with pre-connected machine coupling, duct adapter and static pressure tubing is included in the carry case so that the ALF150 is ready to use from the moment it is unpacked.
