Airflow Instruments Duct Leakage Testers

Why Duct Leakage Testing Matters

In controlled environments, even moderate leakage can shift airflow balance and pressurization. That can complicate containment strategies, affect cleanliness classifications, and raise energy consumption as systems work harder to meet setpoints. Duct leakage testing provides quantified data to support targeted fixes and verify contractor performance.

System Components

• Calibrated Blower: Applies known flow across defined test pressures.
• Precision Pressure Sensors: Measure static and differential pressures with high resolution.
• Flow Measurement: Characterize leakage rates across pressure steps.
• Controls and Display: Guide test setup, capture results, and store data.
• Accessories: Sealing materials and adapters to segment the system for testing.

Use Cases

• Commissioning New Ductwork in GMP Suites
• Verifying Repairs or Modifications to Existing Systems
• Validating Exhaust Systems Serving Hoods and Enclosures
• Troubleshooting Pressurization Drift or ACH Shortfalls
• Supporting Specifications and Project Closeout Documentation

Selection Considerations

• Flow and Pressure Range: Match instrument capabilities to your duct sizes and test protocol.
• Accuracy and Repeatability: Critical for defensible results and trend analyses.
• Portability and Setup Time: Important for projects with many segments.
• Data Handling: Time-stamped logs and exports simplify reporting.
• Service and Calibration: Maintain traceability within your quality system.

Practical Tips

• Coordinate with contractors to isolate sections efficiently.
• Record environmental conditions and fan status.
• Use stepwise pressure testing to diagnose distribution of leaks.
• Combine with smoke visualization for targeted remediation.
