What Happens When A Backward-Inclined Centrifugal Fan Is Run Backwards?

In this video, New York Blower's lead aerodynamic expert and P.E., Matt Raymond discusses a commonly asked question, what happens when a backward-inclined centrifugal fan is run backwards?
Using a clockwise, size 33, airfoil fan mounted on an AMCA accredited test chamber, we are able to evaluate how wheel rotation impacts static pressure, air flow, and break horse power.

    this makes me want to drink water and also increases blood flow towards my right knee cap! good video 🤌

    Hi Matt. Thano you for the precise vid. Does your department design custom multistage blower systems?

    Thanks for watching! If needed, nyb can engineer a system utilizing multiple fans in series (typically 2) mounted on a skid to achieve pressures beyond 200” wg (7 psi or 50 Kpa).

    There doesn't seem to be enough air flowing. Was the motor wired wrong? Never mind.

    What happens with a ceiling fan or a domestic exhaust fan when it's reversed?

    Why are the blades called "backward-inclined" (I've also heard "backward-curved"), then? In relation to what?

    Hi! Thanks so much for reaching out. The term backward inclined comes from the fact that the air across the blade surface deflects in the opposite direction of the rotation. This may seem counterintuitive, but it allows for the fan as a whole to generate static pressure more efficiently because part of the diffusion is done by this backward deflection rather than the fan casing. For this reason, BI fans generally have the highest efficiency and are best suited for medium flow and medium pressure applications. When referencing a BI wheel, the blade angle radially out from the hub will always be less than a 90 degree angle. Hopefully this is helpful. If you have further questions about this topic, please feel free to email us at nyb@nyb.com. Thanks!

    I would love to work for NYB in LaPorte. I know a couple of employees and they rate the company very highly.
