Each of our four series is built for a different job. The 4-72 handles general workshop and building ventilation at low pressure and high flow. The GM series delivers the high-volume air a rice or grain mill needs. The 9-26 is a high-pressure fan for forging-furnace combustion air, and the 6-30 suits pneumatic conveying where both flow and pressure are demanding.
This article lines up the real flow, pressure and power envelopes of each series so you can match your duty point quickly.
