Small houses or houses built to the more stringent energy savings standards have very small amount of leakage through the building envelope. A standard Model 3 Blower Door can be a little too much power to measure at the very low levels of CFM of these types of houses. A Minneapolis Duct Blaster fan can be just the right size when regularly testing these energy efficient homes.
Another application for a Mini-Fan Blower Door System is individual apartment testing for multi-family buildings or when testing to LEED. The lightweight size of the door frame, panel and fan allows you to take the unit out of one apartment and place in the next apartment with minimal effort.
The Energy Conservatory has everything you need to use a Duct Blaster fan as a Blower Door. If you already have a Duct Blaster System, we can provide you with the kit that includes all of the parts necessary to make a Blower Door Kit. We also have a complete kit that includes the Duct Blaster fan and controller and the DG-1000 Pressure and Flow Gauge.
