How Powerful Should My Fan Be For This Filter?
Short Answer: You will likely need a fan that produces between 750 cfm - 1100 cfm @ 0.39" W.g." - 0.63 W.g."
Long Answer: It depends if you add a pre-filter to your project, and what the resistance of that filter is. This will determine the fan velocity needed to reach 70-110 feet per minute coming from the face of the filter, as per ISO Cleanroom Standards. I will provide free consultation to resolve this for you, should you purchase a HEPA filter from me.
