Designed to handle clean air or lightly contaminated airstreams, Daltec Centrifugal Fans are used mainly in ventilation systems and on the clean side of dust collectors. Available in single width (SWSI) and double width (DWDI) designs, these highly efficient fans use formed spinnings or custom contoured inlets to ensure uniform airflow into the impeller. Backward inclined or airfoil impellers feature non-overloading horsepower characteristics.
Various Sizes for Various Tasks
Daltec centrifugal fans are available in a wide assortment of sizes from 105 (10.5 inches diameter) through to 982 (98.25 inches in diameter) and class constructions 1 to 4. Fans can be custom designed to a customer’s specification for either or both custom performance or construction related custom tailoring.
Fan drive arrangements are similar to the industrial exhaust fans with the addition of Arrangement 3 in both SWSI and DWDI also being available.
