Operation

The Duc-Tester will pressurize or depressurize a duct system (with the air handler off) from the main return grille (or blower access opening). The rest of the register openings are taped shut. Duct pressure is measured by static probes in the supply ducts. Airflow is determined by reading flow directly from the DM-2. No computer is required. Setup, taping the registers and getting results takes less than 20 minutes in most homes. The Duc-Tester can also be used in conjunction with a blower door to neutralize duct leaks to indoors to that only duct leakage to outdoors is measured.
