YORK® ICF backward inclined and airfoil fans have the high volume capacities needed for use in heavy manufacturing, hotels and hospitals. When there is no pressure in the system, (the fan is blowing freely), a backward curved centrifugal fan will produce the greatest volume flow. They produce high-pressure output and are among the most energy-efficient fans, especially when used in high-volume applications. They’re also a lot more energy efficient, which is one of the main things that makes them attractive to companies looking for centrifugal fans. The fans are suitable for applications ranging from storage room to fume … Backwards inclined fans are designed for various applications where moisture or lightly contaminated air can be an issue.
