hepa filter blower question
    #940252 - 10/07/02 04:24 PM (15 years, 10 months ago)

Okay I want to buy this great blower I found on the net, and it blows 460CFM. Do you think this would be enough for a 12 X 24 Hepa filter, or is it asking too much of the blower. Do you think I should just get a 12 X 12 Hepa with this blower? I read a lot of post on here and says you need at least 495 CFM to blow through a 12 X 24 Hepa but I don't know I just wanted to get a little feedback.

If you want to calculate what kind of blower you need you have to know how much it blows at static pressure of your HEPA.
Here is the calculation for the filter I'm going to buy:
- Filter size is 457x610mm and it has 150Pa of static pressure.
- 0.5m/s airflow speed at the exit of flowhood is needed.

0.456m*0.61m*0.5m/s*3600s/h = 500m3/h

So I need a blower that can deliver 500m3/h at 150Pa.
