Duct Air Leak Tester

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.

Duct air leak tester.

The above test procedure describes how to determine total duct leakage or how much leakage there is. Total leakage measured with a pressure differential of 0 1 inch w g. Mark any leaks you find with a grease pencil. It s also now equipped with bluetooth as standard for use with bluetooth enabled thermal printers.

Ducts shall be pressure tested to determine air leakage by either of the following. En 12237 ventilation for buildings ductwork strength and leakage of circular sheet metal ducts. Kanomax has developed the most advanced duct air leakage tester dalt for commercial duct systems. 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.

Additional methods leakage to outside. Test apparatustest apparatus duct leakage test system consists of duct leakage test system consists of. You can also try running your hand under other parts of your ductwork to feel for larger leaks. The spots where two air ducts connect are common places for leaks to occur.

Our duct leakage testers are compliant with the following standards. The alf150 2019 model duct leakage tester now comes with automatic closed loop testing as standard allowing you to run leakage tests automatically to set duct static pressures. 1 blower with speed control vfd to generate range of pressure flowrange of pressure flow 2 flow measuring devices flow grid flow station high flow flow grid flow station high flow orifice plate low flow. Leakage class can be calculated using equation 3 but needs to be specified if duct air leakage tests are required.

En 1507 ventilation for buildings sheet metal air ducts with rectangular section requirements for strength and leakage. 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. 25 pa across the system including. If you place your hand near these joints and you feel air coming out you know that there s a leak.

It s designed to be simple to use accurate and extremely convenient. Total leakage measured with a pressure differential of 0 1 inch w g. The alf150 has been given a make over for 2019.
