Airflow Instruments Duct Leakage Testers

Duct leakage impacts energy use, comfort, and ventilation effectiveness. Airflow Instruments Duct Leakage Testers are designed to help you quantify leakage on sheet metal duct sections and document results as part of commissioning and quality control.

Core Capabilities

• Pressurization to Target: Adjust to specified test pressures to match project requirements.
• Calibrated Measurement: Use orifices or calibrated measurement devices to determine airflow leakage rates at the test condition.
• Guided Workflow: On-instrument prompts and accessories help simplify setup and reduce test time in the field.
• Reporting Support: Capture readings, pressure setpoints, and notes for straightforward inclusion in commissioning reports.

Where They Fit

• New Construction: Validate contract documents and workmanship targets during installation.
• Retrofits and Energy Projects: Quantify baseline leakage and verify improvements.
• Code and Standard Support: Designed to align with common testing methods referenced by SMACNA and job specifications.

Best Practices for Reliable Results

• Isolate Sections: Properly seal the test section to avoid bypass.
• Stabilize Pressure: Allow pressure to stabilize before recording leakage at each test point.
• Account for Temperature: Record ambient conditions as required by the test method.
• Document Thoroughly: Include photos, diagrams, and test locations in your final package to support review.

Selection Considerations

• Flow Range: Choose a tester sized for your typical duct dimensions and target leakage classes.
• Mobility: Consider weight, footprint, and transport requirements for multi-floor projects.
• Accessories and Adapters: Stock caps, transitions, and sealing materials to support varied geometries in the field.

By turning a complex procedure into a clear, stepwise process, these testers help you deliver credible ductwork leakage data that supports project closeout and energy performance goals.
