Allegro 9533-25 Confined Space Blower — 8 in Axial AC, 831 CFM Free Air, 25 ft Duct low-light For a more budget-focused optionEditor's take (4. 6 5): The Allegro 9533 25 Confined Space Blower is a workhorse 8 inch axial unit light polyethylene housing, 25 ft of duct, and the flexibility to blow fresh air in or exhaust bad air out. Read the airflow honestly: 831 CFM is a free air number that drops once duct and bends are in play. And it's not explosion proof, so match the blower to your atmosphere. Pair it with a 4 gas meter and a written entry plan. Check Price on Amazon As
