Product Details

The Airflow Positive and Negative Duct Accreditation (PANDA) System PAN341 Series 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 European standards like EN12237, EN1507, EN13779, EUROVENT 2/2 standards and with A merican standards like SMACNA, enhancing energy savings in buildings.

Note: PAN341 is not available for sale in the U.S.

Features and Benefits

  • Positive and Negative Duct Leakage Testing in one rig 
  •  Energy savings by testing and minimizing duct leaks 
  • Compliant with the following standards:   
    • EN13779 Ventilation for Buildings—Achieve a good air quality with acceptable installation and running costs
    • EN12237 Ventilation for Buildings—Ductwork Strenght and Leakage of Circular Sheet Metal Ducts
    • EN12237 Ventilation for Buildings—Test procedures with measuring methods
    • HVCA DW/143 Ventilation for Buildings—Guidance document for Ductwork leakageTesting
    • EUROVENT 2/2 Air Leakage Rate in Sheet Metal Air Distribution Systems 
    • SMACNA Sheet Metal And Air Conditioning Contractors National Association
  •  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 PAN341 comes with standard Airflow TA465-P Multi-Function Instrument and PVM610 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
  • Carry weight of 45kg (99lbs)

  • Are the leakage rates corrected for Density?
    Yes! Provided the TA465-P or TA460-P is used, the leakage rate is corrected for density to standard conditions.   
  • Can I use my existing instruments with the PANDA?
     All TA465-P or TA460-P units that shipped after 20 August 2009 include the Duct Leakage Application as standard, and can be used for the leakage measurement. If you have a TA460-P that shipped before 20 August 2009, it needs to be returned to TSI for a firmware upgrade. For the static pressure measurement, we recommend using a PVM610 or PVM620.   
  • Can the PANDA be used outside?
    No, it should no be exposed to damp or wet conditions. 
  • Does the PANDA cover the same operating ranges as the HVLT and LVLT leakage testers?
    The PANDA was designed to cover or improve upon the pressure operating range covered by both the HVLT and the LVLT. The working flow range was designed to be suitable for the majority of applications. The PANDA cannot achieve the maximum flow from the LVLT and was never intended to do so as the extra size required to achieve this would be prohibitive with regards to transportation.  
  • Does the PANDA offer better control than the previous leakage testers?
    Yes! Again, using the latest inverter technology offers precise, stable control over its wide operating range.  
  • Is the PANDA easily transportable?
    Yes! The product was designed to fit into the back of most estate cars, some larger hatchbacks, and small vans.  
  • Is the PANDA quieter than the previous leakage testers?
    Yes! The product uses the latest inverter technology to offer quiet and efficient operation.  
  • What standards apply to Leakage Testing and the PANDA?
    BS EN 12237:2003. Ventilation for buildings – Ductwork – Strength and leakage of circular sheet metal ducts. BS EN 1507:2006. Ventilation for buildings – Sheet metal air ducts with rectangular section – Requirements for strength and leakage.  DW/143 HVCA: A practical guide to Ductwork leakage testing. Eurovent 2/2 – 1996. Air leakage rate in sheet metal air distribution systems. 
  • What supply voltage needs to be supplied to the PANDA?
    There are 2 versions of the PANDA – (1) 208-240v/1Ph/50-60hz and (2) 110-120v/1Ph/50-60hz.  
  • Why negative pressure testing?
    The latest standards (see above) require that ducting be subjected to test pressures, both positive and negative, not lower than its design operating pressure.
