    • Complete with everything you need for fully automated Blower Door testing.
    • Built-in Cruise Control allows you to automatically control the Blower Door fan to maintain a constant 75 Pa, 50 Pa, 25 Pa or 0 Pa building pressure without having the gauge connected to a computer.
    • Our lightweight, rugged, injection molded fan housing has a 5 year “no questions asked” warranty.
    • Precise, stable flow measurements without the need for gauge dampening.
    • The Model 3 Fan provides quick and accurate flow measurements from 300 to 6,300 CFM (includes Flow Rings A and B).
    • Optional Flow Rings C, D and E will measure down to 11 CFM.
    • Variable fan speed control (solid state – cruise control compatible).
    • Both 110V/60 Hz and 220V/50 Hz models.
    • The standard Model 3 Minneapolis Blower Door™ system includes a single fan, the DG-700 pressure and flow gauge with Cruise Control, the adjustable aluminium frame and nylon panel, and our TECTITE software.

    Instrumentation Options

    • The DG-700 digital pressure and flow gauge is the latest instrumentation option for the Model 3 Blower Door. The DG-700 contains 2 precision pressure sensors which provide simultaneous display of both building pressure and Blower Door fan flow readings. It’s specialized “Baseline” and “CFM @50” features makes it extremely easy to get quick and accurate airtightness test results.
    • The DG-700’s Cruise Control feature allows you to automatically control the Blower Door fan to maintain a constant 75 Pa, 50 Pa, 25 Pa or 0 Pa building pressure without having the gauge connected to a computer.
    • In addition, the DG-700 has both a USB and RS-232 port that can be used along with a laptop computer and our TECTITE software to conduct fully automated Blower Door tests. Our TECLOG3 software is ideal for testing large commercial buildings.
    • The Automated Performance Testing (APT) System also enables you to fully automate the Blower Door test from your laptop computer. The APT System can be purchased with up to 6 additional pressure channels to simultaneously monitor multiple building zone pressures during a Blower Door test.

    Lightweight, Durable Door Frame and Panel
    The innovative design of our adjustable aluminum frame and durable nylon panel is the result of years of refinements based on the experience of thousands of users. There is no easier way to seal a Blower Door fan into a door opening.
