Minneapolis Blower Door Model 3, No Manometer

If you are looking for the complete blower doors system, including the DG-700 manometer, see Minneapolis Blower Door.

This package of the Minneapolis Model 3 Blower Door is offered without a DG-700 or DG-1000 Pressure and Flow Gauge. This allows for significant cost savings for those who already have a TEC manometer, or will be purchasing one with another Energy Conservatory product. The DG-700 is the measurement backbone of most products from The Energy Conservatory and is included with many packages. If you already own a Minneapolis Duct Blaster, for instance, you can use the same manometer to run the Minneapolis Blower Door.

The blower door cannot be operated without the DG-700 or DG-1000, and some of the features below assume that you have provided a DG-700 or DG-1000 from another package.

  • Quick and accurate flow measurements from 300 to 6,300 CFM. Optional rings C, D and E will measure down to 11 CFM.
  • Powerful 3/4 hp motor provides continuous flow for testing and air sealing work.
  • Auto-zeroing of both channels eliminates sensitivity to orientation and temperature.
  • Specialized @50 and @25 test modes make it simple to conduct one-point airtightness tests of buildings and duct systems. Test results can be displayed in CFM or square inches of leakage area.
  • Cruise 75, 50, 25 and 0 Pa building pressure without connection to a computer. The Cruise Control feature automatically adjusts the speed of the Blower Door fan to maintain a constant building pressure while you perform additional diagnostics or air-sealing procedures.
  • Four separate time-averaging modes (1, 5, 10 second & long-term) allow you to accurately measure fluctuating pressures.
  • "Baseline" feature allows the user to measure and record a baseline pressure reading, and then display the baseline adjusted reading.
  • The DG-700 (not included in this package) can be used along with a computer and specialized TEC software: TECTITE to conduct automated Blower Door tests; and TECLOG for data logging of pressure measurements from both channels.


  • Fan with variable speed controller and fan control cable
  • Two Flow Rings (A and B) and No Flow Plate
  • TECTITE Building Airtightness Testing Software
  • Fabric door panel with viewing window
  • Five piece adjustable aluminum door frame and frame case
  • USB cable - 16 feet (5 meters) long
  • Does not include DG-700 gauge.
