Vertical Flow Hood
    #27679127 - 03/02/22 03:23 AM (2 years, 10 months ago)

Is it possible to take a vertical flow hood and lay it down and use it as a horizontal hood?

Maybe but probably not.

I know some people that use a vertical hood just fine. Just a different technique in how you position your stuff and hands.

Vertical flow hoods typically have lower velocity (55-65cfm) than horizontal (85-95cfm). But they are on par with typical flows from FFU’s. Sandman is correct, they just require an adjustment in technique.

cfm is not a velocity

And vertical hoods should have the same speed as a horizontal hood but there are many models and types out there. 90 FPM is standard for vertical hoods as well as horizontal according to ISO 14644.

You are correct, I should have typed FPM.
