Duct Technologies Pressure Test & Air Tightness Class
Duct Technologies Pressure test & Air tightness class as set out in DW143 is a determination of how leaky your ductwork is. Leaky ducts can have a significant impact on energy consumption and IAQ (Indoor Air Quality). A pressure test is carried out by blanking off sections of ductwork to create a constant pressure and using a measuring device to determine ductwork leakage in accordance with DW144.
We use a Panda 341 ductwork pressure testing rig which has been independently verified & collaborated.
