The Air King 9670 30-Inch I-Beam Mount Fan is the largest fan in Air King’s standard industrial-fan line, with a 1/3-horsepower motor delivering 8,780 CFM and a clamping bracket sized for overhead steel I-beams in warehouses, manufacturing facilities, and agricultural structures.
The 30-inch blade pushes nearly 50 percent more airflow than the 24-inch I-beam mount sibling — enough to ventilate a 50 by 80 foot bay or push spot cooling across a single station from 20 feet overhead. The I-beam clamp bolts onto standard structural-steel flanges with no need for separate brackets or wood joists, so the fan installs quickly into existing pre-engineered metal buildings.
Air King manufactures industrial fans in West Chester, Pennsylvania — the 9670 carries Made in USA designation per the manufacturer’s listing. Pair the 9670 with smaller 9671 24-inch I-beam mount fans when you need a graduated-output layout, or with the 9335 oscillating 30-inch ceiling fan when ceiling joists are available instead of structural steel.
