Ductwork Leakage Testers

Maintain cleanroom performance, pressure cascades, and air change targets with ductwork leakage testers designed for life sciences facilities. Accurate leakage testing supports commissioning, qualification, and ongoing facility maintenance by quantifying leaks that can compromise airflow control, contamination containment, and energy efficiency. TSI solutions for positive and negative duct accreditation help contractors, certifiers, and facilities teams validate duct integrity across HEPA filter banks, risers, and branches serving ISO-classified spaces, biosafety laboratories, hospital pharmacies, and vivariums. Portable configurations, clear test controls, and traceable measurements help streamline documentation and support compliance programs tied to GMP and quality systems. From project start-up to routine requalification, duct leakage testing helps identify issues early and helps reduce the risk of pressure instability, product loss, and unplanned downtime.

Duct leakage directly affects airflow stability, pressure differentials, and contamination control — core performance factors in life sciences environments. Even small leaks can shift pressure cascades, disrupt air change targets, and drive higher fan energy. Purpose-built ductwork leakage testers help teams quantify leakage rates at specified test pressures so they can prioritize remediation and verify system integrity before, during, and after qualification.

Where It Matters

  • Cleanrooms and GMP suites: Support classification programs and help maintain pressure hierarchies between graded spaces.
  • Biosafety laboratories: Help sustain directional airflow objectives essential to containment strategies.
  • Hospital pharmacies (USP 797/800): Support room pressurization and ventilation program documentation.
  • Vivariums and procedure rooms: Help stabilize temperature, humidity, and ventilation setpoints linked to animal welfare and research outcomes.

How Testing Works

  • Test Mode: Apply positive or negative pressure to isolated duct sections or filter banks using a calibrated source.
  • Measurement: Record pressure and flow to calculate leakage at standardized test points.
  • Documentation: Produce digital records that support commissioning reports, deviation investigations, and requalification audits.

What To Look For in a Tester

  • Dual-mode capability: Positive and negative test options for flexibility across systems and standards.
  • Traceable measurement: Calibrations that support quality systems and audit readiness.
  • Practical portability: Compact configuration for work at height and tight mechanical spaces.
  • Clear controls and displays: Simple setup and readable results for consistent execution.
  • Data and reporting: Structured outputs that integrate with commissioning and quality documentation.

Applications Across the Project Lifecycle

  • Design and construction: Verify duct sections prior to ceiling closure to help avoid costly rework.
  • Commissioning and TAB: Validate leakage so balancing efforts focus on final performance, not hidden defects.
  • Qualification and requalification: Provide repeatable evidence that supports quality programs and change control.
  • Maintenance and troubleshooting: Pinpoint sources of drift when pressure or airflow targets trend out of range.
