Duct Testing Systems : Q32 Duc-Tester

Our Duct Testing Systems are in use all over the world measuring air leakage in duct systems and tight houses. Our equipment is manufactured and fully calibrated against NIST traceable devices.

The Retrotec DucTester is designed specifically to measure residential duct leakage. It is used to locate duct leaks and to measure the results of duct sealing. The Model Q32 DucTester is used to verify duct leakage for compliance with codes such as Title 24 in California.

The typical 5-ton air-conditioning system must have 120 CFM of leakage or less to pass California standards. The Q32 will easily test any residential system as it can generate up to 600 CFM and has three separate flow ranges.

With the Retrotec DM-2A Digital Gauge, testing duct work has never been easier! Simply set up the equipment, click on the desired test pressure and walk away: DM-2A will run the test for you, as it adjusts speed and measures duct leakage automatically.

Automated Duct Testing without a computer? for measuring duct leakage in residential & light commercial buildings.

Q32 consists of a Duc-Tester Module, a DM-2 Digital gauge and a 12 foot flex-duct with flanges for mounting on the return register. Click on the desired test pressure and walk away; the DM-2 will run the test for you. Case for DM-2 and grill mask dispenser not included.

DM-2 adjusts speed and measures duct leakage automatically.

The DU220 fan unit has three flow ranges.

The Retrotec Duc-Tester is designed specifically to measure residential duct leakage. It can then be used to locate duct leaks and to measure the results of duct sealing. Use the Model Q32 Duc-Tester to verify duct leakage for compliance with codes such as Title 24 in California. The typical 5 Ton air-conditioning system must have 120 cfm of leakage or less to pass California standards. The Q32 will easily test any residential system because it will create 600 cfm which is 5 times more than that.

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 so that only duct leakage to outdoors is measured.
