The company's broad product line includes radial fans with backward curved or forward curved motorized impellers, free-running or mounted in a housing, large axial fans, small axial fans, single and double inlet blowers.
Axial Fans move air at 180°, parallel to the shaft of the impeller. Standard axial fans are best suited in low static pressure applications, but selected powerful Rosenberg axial fans reach up to 1.6" of pressure!...
Backward Curved Impellers handle high static pressure applications the best. They are compact and energy efficient, a good choice to reduce handling and operating costs. Rosenberg backward curved fans are available in sizes from 225 to 710 mm with static pressure up to 9" and maximum airflow of 11,000 CFM. Ecofit backward curved fans range in size from 133 to 315 mm featuring polyamide or steel impellers, up to 1,060 CFM airflow and static pressure up to 3.2”...
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)...
Rosenberg and Ecofit EC fans are maintenance free and highly efficient, reducing energy consumption up to 35%. Integrated controller technology allows continuous control of pressure and airflow. Ecofit EC fans are backward curved only and available in sizes from 192 to 315 mm offering up to 1486 CFM. Rosenberg backward curved EC fans come in sizes from 225 to 710 mm and deliver up to 6.75 inches of static pressure or up to 11,000 CFM of airflow. Rosenberg also ...
