TSI Duct Leakage Testers

This product is now obsolete and has been replaced by the PAN315 & PAN341 Positive and Negative Duct Accreditation (PANDA) System.

The Positive and Negative Duct Accreditation (PANDA) system provides contractors, commissioning engineers, and research and development technicians with the best in class choice of test equipment to quantify air leakage in ductwork and other areas as well as the ability to measure the performance of ducted systems. The PANDA provides a fast, accurate, automated solution and helps to ensure compliance with EN12237, EN1507 and EUROVENT 2/2 standards, enhancing energy savings in buildings.


  Positive and Negative Duct Leakage Testing in one rig
  Energy savings by testing and minimizing duct leaks
  Compliant with the following standards: EN12237 Ventilation for Buildings-Ductwork-Strength & Leakage of Circular Sheet Metal Ducts, EN1507 Ventilation for Buildings-Sheet Metal ducts with Rectangular Section-Requirements for Strength and Leakage and EUROVENT 2/2 Air Leakage Rate in Sheet Metal Air Distribution Systems
  Accuracy is ± 2,5% of volume flow
  Unique performance and fan speed control charge up of duct system to test static pressure within minutes
  Fits in the back of vans and estate cars
  Model PAN321 comes with standard Airflow TA460-P Multi-Function Instrument and PVM620 Micromanometer.
  Automatically calculates leakage rate in real time
  Simultaneous displays flow leakage rate and static pressure
  Provides a pass/fail indication for a given tightness class
  Automatically corrects actual volume flow leakage rate to Standard Temperature and Pressure (STP)
  Monitors barometric pressure and temperature in real time
  Stores data that can be downloaded for report generation and documentation
  Works with Model 8934 Portable Printer
