We stock just a solitary forward curved fan on its own the rest of our forward curved fans come as complete blowers and can be found in the Blower units section.
Forward curved fans work differently from backward curved fans as they can only be used effectively with the use of a scroll. There is a high kinetic energy in the air stream that can only be converted to useful static pressure by the use of a scroll. The best performance is always achieved when the optimum point is found; this varies depending on if the blade is narrow or wide. Along with scrolls an inlet ring should be used to further improve the effectiveness of the unit, without an inlet ring a reduction of 6% is generally expected in performance.
