Ductwork Pressure Testing Equipment

Eurovent 2 2 leakage rate in sheet metal air distribution systems.

Ductwork pressure testing equipment.

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. 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. The alf 150 duct leakage tester is a low cost compact light weight and totally self contained unit. Duct leakage test system consists of duct leakage test system consists of.

The required capacity of a leakage test meter should be examined in relation to the duct leakage classification chart. 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. Besa dw143 outlines the allowable leakage rates for low medium and high class ductwork systems.

Dw 143 ductwork leakage testing. Smacna air duct leakage test manual. Conducting a test determines if there are unsealed cracks resulting in air leakages that require immediate sealing. Hasman s high sensitivity ductwork pressure testing equipment allows us to test all ductwork classes from a to d.

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. Testing is only mandatory for ductwork classes b to d but with increased attention on building s energy efficiencies testing of class a systems may also be specified. En 12237 ventilation for buildings ductwork strength and leakage of circular sheet metal ducts. Digital airflow meter for both supply positive and exhaust negative duct systems with direct scfm leakage readout.

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. Blower doors and duct testers measure airtightness in homes and buildings with blower doors and duct testers. 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. Color coded vinyl tubing for static pressure gauge and airflow meter connections.
