If you ventilate a solvent storage cabinet you lose the fire rating and it is no longer approved storage.

If you over ventilate a low flow hood it often has turbulence issues and does not work properly. You could get around that with a manual damper set properly.

Good afternoon-

I would really appreciate hearing from you if you have recently installed a Kewaunee Ultra Low Volume or another KewauneeÊ low volume fume hood:

a) What has been your good/bad/learning experience with theÊ Ultra low Constant Volume fume hoodÊ (I believeÊthe model # is H50)?Ê ÊIf a differentÊmodel-- which one?
b) what is your hood's typical face velocity?
c) can one or two Kewaunee flammable cabinets be chosen for underneathÊ(depending on size of the hood)?
d) this fume hood is going into an older buildingÊwhich does not have Phoenix or other controls and will have supplyÊand exhaust air as though it is a 'standard' constant volume hood--will this work?

I am also trying to ask similar questions of Kewaunee but todayÊI have not been able to successfully reach anyone...
Many thanks,
Margaret
