Roof Vent out 22ft with infinity fan

[CRAFL]

Hi there!

I am looking for some help or suggestions related to fans for vent out.

I have the opportunity to get a small office that has an exhaust next to the AC Unit that goes all the way up to the roof of the building (22 ft)

I have two glowforges with two infinity fans ( one for each ) and I wonder if this fans will be strong enough to exhaust everything all the way up.

Do you think these two fans will be strong enough to exhaust everything all the way through the roof? Or do I need to get something stronger?

Attached is the picture of the fans That I own.

Thanks in advance for your response!!

I have a 6" Vivosun that is virtually silent, it’s 25’ away from the GF via a 4" hose, with another 10’ of 6" hose out to the window. Works just fine, no odor whatsoever.
