The Allegro Industries 9533 is a new 8-inch plastic axial compaxial blower designed for confined space ventilation, fume extraction, and air circulation in industrial and construction environments. The motor runs on 115/230V AC dual voltage, drawing 4.8/2.4A at 60 Hz (4.5/2.7A at 50 Hz) at 3450 RPM (60 Hz) / 2850 RPM (50 Hz), and is rated at 1/3 HP, 1-phase, with built-in thermal overload protection that automatically shuts the unit down if it overheats. Air delivery is rated at 831 CFM free air, 705 CFM with one 90° bend, and 585 CFM with two 90° bends, making it well-suited for ducting through confined space entry points using standard 8-inch ventilation hose. The orange UV-resistant polyethylene housing is lightweight and impact-resistant, with an integrated carry handle, cord wrap, and wire safety guards on both inlet and outlet faces; it is ETL listed and certified to CSA Standard C22.2 No. 113 for use as a fan and ventilator.
