I was involved with the initial phases of a rather large purchase of Erlab GreenFumeHoods and a smaller purchase and installation of AirClean ductless systems for rotary evaporators while I was at a previous job. In both cases, traditional ducting was
not an option. The Erlab hoods were being purchased for an organic chemistry teaching lab. During the vetting of this system, I had to provide a list of all of the chemicals that will be used within the hood in order to proceed as the manufacturer wanted
to verify that their filtration systems would work. I had to do the same when ordering the rotary evaporator ductless systems.
As part of our internal SOPs, the Erlab hoods were not allowed to be used for research purposes. This is because as soon as one changes from teaching labs, where all of the components being used are planned and in known quantities, to research operations,
there is no control over what may be passing through the hoods. I know the Erlab hoods have been in operation for about a year at that facility and if you email me (bchance**At_Symbol_Here**princeton.edu) directly, I will put you in touch with the manager running that facility.
He speaks very highly of the Erlab systems.
I hope this helps,

I was asked by my department to assist in deciding whether to purchase ductless fumehoods for our undergraduate chemistry labs. We are planning to use these for flammable solvents, and reactions involving HCl and NaOH. These hoods will be used by
undergraduates for research also. Any input on the safety issues involved with these equipments versus the regular hoods would be appreciated.
