Key Features
Automated guided testing
The touchscreen guides setup and executes leakage tests using configured duct parameters.
Wide dual-nozzle coverage
Large and small nozzle ranges cover low- and higher-flow leakage conditions without orifice plates.
Positive and negative modes
Quick hose reconfiguration supports both pressure and decay-style test workflows.
Jobsite mobility
Pneumatic tires and a stair-walker dolly support transport to rooftop and constrained locations.

Applications
Duct leakage classification
Quantify leakage before system handover or acceptance.
Existing-system tightness checks
Evaluate leakage before and after sealing or renovation work.
Fabrication and installation verification
Confirm ductwork performance against the project’s specified class.
Air-distribution loss assessment
Identify leakage that can reduce delivered airflow and increase fan energy.
