  • Find and fix duct leaks to save energy
  • High-flow fan for testing large duct sections
  • Pressurizes duct quickly, allowing testing to begin in minutes
  • Includes TSI Model 9565-P & Model 5825 instruments
  • Measure pressure, volume flow, temp, & barometric pressure
  • NIST Certificate Included

The TSI Alnor PAN231 series duct leakage testers provide 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.

Pass/fail reporting for standards:

  • SMACNA HVAC air duct leakage test manual
  • 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 & leakage
  • EUROVENT 2/2 air leakage rate in sheet metal air distribution systems

The TSI Alnor PAN231 positive and negative duct testing applications are well suited for facility managers and HVAC installers. With the included 5815 and 9565-P instruments you can:

  • Automatically calculate leakage rate in real time
  • Display flow leakage rate and static pressure simultaneously
  • Monitor barometric pressure and temperature to automatically correct to Standard Temperature & Pressure (STP)
  • Simplify report generation and documentation by downloading stored data
