Blowers are forward curved impellers (radial fans) in a scrolled housing. They provide higher static pressures than axial fans and are also more efficient for high pressure applications. Rosenberg forward curved blowers have inlet diameters of 195 mm to 400 mm producing static pressures of up to 4.5 inches or airflow of up to 7,000 CFM. The Ecofit line includes inlet diameters from 108 mm to 200-mm (single inlet) and 120 mm to 200 mm (double inlet).
