Air Duct Leak Tester

Ductwork leakage testers the tsi positive and negative duct accreditation panda system pan200 series is designed to provide fast accurate duct leakage detection as well as duct performance measurements.

Air duct leak tester.

Check the duct joints. The spots where two air ducts connect are common places for leaks to occur. Our duct leakage testers are compliant with the following standards. You can also try running your hand under other parts of your ductwork to feel for larger leaks.

Figure 5 1l from the 2012 smacna hvac air duct leakage test manual shows the allowable leakage as a function of duct leakage classification and static pressure in the duct. Though built tough with an on board powerful motor the dalt 6900 is very easy to transport on its pneumatic tires and leaves little to no footprint on the job site. Ducts shall be pressure tested to determine air leakage by either of the following. Total leakage measured with a pressure differential of 0 1 inch w g.

Apparent differences of about ten percent between fan delivery and sum of airflow measurements at terminals do not necessarily mean poor sealing and excess leakage. Mark any leaks you find with a grease pencil. Potential accuracy of flow measurements should be evaluated. Where no specific duct pressure class designations are provided byclass designations are provided by the designer the 1 water gage pressure class is the basis of.

Eurovent 2 2 leakage rate in sheet metal air distribution systems. Quote fromquote from hvac air duct leakage testhvac air duct leakage test manual smacna. The instrument provides step by step test configuration and automated leakage testing based on the smacna hvac air duct leakage test manual and is accurate to 2 5 of reading. 25 pa across the system including manufacturer s air handler enclosure all registers taped or otherwise sealed post construction test.

The hvac air duct leakage test manual provides practical and detailed procedures for conducting leakage tests. Total leakage measured with a pressure differential of 0 1 inch w g. If you place your hand near these joints and you feel air coming out you know that there s a leak. En 12237 ventilation for buildings ductwork strength and leakage of circular sheet metal ducts.

A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow. Leakage class can be calculated using equation 3 but needs to be specified if duct air leakage tests are required.
