Overview

Features

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.

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:

 

- EN12237 Ventilation for Buildings—Ductwork—Strength & Leakage of Circular Sheet Metal Ducts

- EUROVENT 2/2 Air Leakage Rate in Sheet Metal Air Distribution Systems

- SMACNA Air Duct Leakage Testing

- EN1507 Ventilation for Buildings—Sheet Metal ducts with Rectangular Section—Requirements for Strength and Leakage

  • 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 PAN331 comes with standard Airflow TA465 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

Technical

Fan performance

Please see the TSI PANDA fan performance curve .pdf datasheet for full details of the instruments performance. Nominal performance figure are:-

190 l/s at 500Pa
180 l/s at 1000Pa
150 l/s at 1500Pa
120 l/s at 2000Pa
50 l/s at 2500Pa

IMPORTANT NOTES

Some Instrument Hire models are supplied with the TA460 version of the multi purpose test meter which does not have the Bluetooth communications facility or includes the SMACNA duct leakage standard.

For Instrument Hire models these are not suitable for use in cleanrooms or other "sterile" environments.

The TSI PANDA model 341 is available to purchase, please see separate entry in the sales section for details.

How to set up the TSI PANDA duct leakage tester

FAQs

Q

Why can’t I reach or maintain my required test pressure in the ducting ?

A

Not being able to reach pressure can be caused by, a large leak in the system, the surface area is too large for that test rig, incorrect set up on manometers, or wrong cone fitted.

Q

How do I know if the TSI PANDA is the correct unit to carry out my test ?

A

You need to know the class of ducting to be tested which establishes the required testing pressure in kPa, and the surface area of the ducting to be checked.  Using this information you can then calculate the allowable leakage rate and using the Pressure Vs. Flow performance graph for the instrument establish if the unit is capable of undertaking the test i.e. below the line OK, above the either chose a different leakage tested or test a smaller area of ducting.

Q

How do I know if my set-up is correct before I start my leakage test ?

A

A detailed explanation on the equipment set-up procedure can be seen by watching the video in the download section of this product page.
