Minneapolis Duct Blaster® System with DG-1000

The Minneapolis Duct Blaster® is a calibrated air flow measurement system designed to test and document the airtightness of forced air duct systems in both houses and light commercial buildings.

Minneapolis Duct Blaster® System Features

Provides quick and accurate airtightness measurements from 10 – 1,500 CFM
Compatible for both pressurization and depressurization testing
Lightweight fan weighs only 7 pounds
Ideal for use in new construction applications where a Blower Door can’t be used (e.g. before sheet rock is installed)
Use to certify code compliance for total duct leakage and duct leakage to the outside as in IECC 2009 and 2012
