The Air King 9424 24-Inch I-Beam Mount Fan is the 1/4-horsepower variant of the 24-inch I-beam mount platform, delivering 5,130 CFM at a slightly lower CFM and motor draw than the 1/3-horsepower 9671 sibling. The 1/4-HP version is sized for medium-bay warehouses, ag buildings, and shop spaces where the 9671’s full output would be excess capacity.
Like the rest of the I-beam mount line, the 9424 uses a heavy bolt-clamp bracket that grips standard structural-steel flanges directly — no need for ceiling joists or separate hangers. The sealed continuous-duty motor is rated for full-shift industrial use, the three-speed pull chain keeps controls accessible from below, and the black powder-coat finish hides shop dust over time.
Air King manufactures industrial fans in West Chester, Pennsylvania — the 9424 carries Made in USA designation per the manufacturer’s listing. Pair the 9424 with the higher-output 9671 24-inch (1/3-HP, 5,770 CFM) for graduated-zone airflow, or with a 9670 30-inch I-beam mount when a single bay needs maximum CFM coverage.
