QMG Door Fan System
Here is our most powerful airflow diagnostic system, boasting a minimum of three commercial-strength 3300 Series door fans that can be left running all day, at any speed, without overheating. The versatile, hard-panel frame securely holds all three fans, fits virtually any doorway, and can be assembled and taken apart in a matter of minutes.
This system has been used to test some of the largest buildings in the world, and it can be ordered with three, six, twelve, or even twenty-four door fans, ensuring that no building will be beyond the scope of your testing capabilities.
