- A duct leakage tester is a diagnostic tool designed to measure the airtightness of HVAC ductwork to improve energy conservation. The test consists of measuring the amount of air moving through the fan, and quantify the duct leakage at the test pressure.
- The blower door Air leakage fan can measure the building airtightness from an energy efficient house or an old draughty building. This scalable system can also measure even the largest building by using more than one blower door unit in parallel.
