Ductwork Pressure Testing Equipment

Blower doors and duct testers measure airtightness in homes and buildings with blower doors and duct testers.

Ductwork pressure testing equipment.

Conducting a test determines if there are unsealed cracks resulting in air leakages that require immediate sealing. Color coded vinyl tubing for static pressure gauge and airflow meter connections. A test meter must have a fan that can produce the target cfm at a static pressure that is a combination of the duct test pressure plus other system losses. Variable speed blower with gradual control used for all four leakage test ranges.

Commercially duct pressurization testing is the first of many tests required to verify the actual performance of the installed system. Commissioning engineers are provided with a high quality duct leakage tester with everything needed to test duct work systems for leakage under both positive and negative pressure. 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 3 p i t t t 3 pressure instruments manometers. En 12237 ventilation for buildings ductwork strength and leakage of circular sheet metal ducts.

Dw 143 ductwork leakage testing. 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. Eurovent 2 2 leakage rate in sheet metal air distribution systems. The required capacity of a leakage test meter should be examined in relation to the duct leakage classification chart.

With our equipment you can perform airtightness checks to reduce energy costs and interior air quality for overall comfort. Digital static pressure gauge. Digital airflow meter for both supply positive and exhaust negative duct systems with direct scfm leakage readout. Besa dw143 outlines the allowable leakage rates for low medium and high class ductwork systems.

Duct leakage test system consists of duct leakage test system consists of. 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. Smacna air duct leakage test manual. It s understood that duct pressurization is a dead test because at this point the equipment including the fan heating and refrigeration systems are not yet operable.

The alf 150 duct leakage tester is a low cost compact light weight and totally self contained unit.
