Air Tightness Testing System Mdoel GTI658

GTI658 building air tightness test system is mainly used for the air tightness test of the whole building and its interior indoor space. The fan pressure method (blower door method) is adopted. In a sealed building environment,the fan is used to establish the pressure difference between the interior and exterior of the building, and the indoor pressure reaches the ideal differential pressure (10-100 Pa) by adjusting the fan rotation speed, and the air volume flow delivered by the fan is measured, which is equal to the flow volume passing through the unsealed part of the building. It is used to evaluate the air tightness level of the building and find leakage points.
