Installing Fumehoods In a Lab
Installing Fumehoods In a Lab
(OP)
Hi,
I need to install 2 new fumehoods in a Lab that already contains 20 Fumehoods.
I've been told the AHU is maxed out & can't support any more fumehoods.
I have scope to replace some of the larger old fumehoods with smaller Fumehoods.
I want to know if the maximum amount of fumehoods is a function of the Design Volume of each fumehood or the amount of space open to the Lab at each fumehood sash.
Basically, can i replace a large fumehood of volume X with 2 smaller fumehoods of Volume X/2.
Thanks
KC

If you do not enough makeup air, it will hard to exhaust. You also will a have time opening doors to the building.
Replacing a large fumehood of volume X with 2 smaller fumehoods of Volume X/2 is acceptable.

77JQX is correct in stating that the face velocity is important, but that issue has to do with the capture of the fumes.
