The ALF150 Duct Leakage Tester is available for hire at extremely competitively weekly rates and can be hired for up to 10 weeks at a time.

Sorry, this product is not available in your country SKU: ALF-150-HIRE Category: Tags: ,

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. It also features a closed loop control test mode as standard, providing a fully automatic test facility for increased productivity.
The instrument is equipped with SD Card and USB 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.

The ALF150 provides a closed loop PID control feature that allows you to run a closed loop controlled leakage test. The user can setup a test to SMACNA, Eurovent 2/2 and DW/143. They can enter the size of the duct, the test pressure, duration, class of ductwork and the ALF controller will then calculate the allowable max leakage for the test. The controller will then run the test and pressurize the ductwork to the set pressure and monitor the leakage rate. Based on the performance of the ductwork, the controller will indicate if the ductwork passed the test.

The ALF150 utilize three conical inlet nozzles designed to ISO5801:2007 and each unit is supplied with a fully calibrated instrument. The lightweight design and compact size of the unit mean that it can be lifted by one person and fit in even the smallest of hatchback boot compartments with room to spare for the accessories!
