Is this Flow Hood a good deal?
    #18032655 - 03/30/13 12:04 PM (11 years, 1 day ago)

Hey guys!
I found a local equipment dealer and they have a 33" x 24" x 23" laminar flow hood for sale. It has a HEPA filter and is fully functioning. They are asking for $800, is this a good deal? I will post a pic of it.



Thanks!

I can't tell by the pic.  Is the filter in the back or the top?

You could build one for half that price, fungiperfecti sells some for like $450 new i think.

This one seems quite a bit nicer, and I won't have to pay for shipping, I'll just drive over and pick it up. Also, fungi perfecti's start at $529. I will probably get this one for under $800 since i can pay in cash, that's just their listing price.

Build your own and save at least $300.

Horizontal hoods are better for what we do.  Here is an older thread that explains why.

Make sure and inspect the filter, prefilter, etc.

I just like the DIY approach..  But to each their own, if it works and you got the cash to flop.. by all means.  Start it up, give it a flame test, youll know after your first batch whether the hood is any good.

So if I make my own, what size fan do I need? Some have CFM ratings and some just have sizes. And what sites do you recommend for buying HEPA filters?

Fungiperfecti website has the hepa filters, like $100-$150

Fans I found are Dayton squirrel cage fans.  450-500cfm

build a standard box outta 3/4inch good quality wood and install filter..  setup a prefilter for your blower fan.. turn it on and get to work :laugh:

expect total cost between $350-$450 for a brand new setup, used or salaved parts can be found.. but always start with a new filter, itll last you a life time.

I thought I would save money by building my own.. i should have just bought the one off their website, between the time, the tools required and all my buildling..

they are really charging you like $150 in labor to make the thing.. so its worth it in my opinion.. but if you like building, and your a hands on person and good with a saw and power tools.. make that shit its fun

So for a 24" x 24" x 6" 99.99% HEPA filter, and an average prefilter, what CFM do I need for my fan? It seems as though I will need about 400CFM for such a filter. 4 sq. ft. x 100 ft/min = 400CFM? Will an in line blower such as this one suffice?  I checked the rated velocity on the filter and it is 175 FPM. Does that mean I will need a fan that puts out 700 CFM? ( 4sq. ft. x 175 FPM = 700CFM )
Thanks!!

That is a fan, you need a blower.

A few links that might help:

Boris's Home-Made Flowhood Tek

TranscendingLife's GloveBox Tek

Damion5050's Flow Hood Build

oderus urungus's Laminar flow hood build (pics) [about $140-150.]

Lotte & Thomas Orchids Laminar flow hood construction

Got a bit carried away with the links but it should give you some ideas and information.  Flow hoods can be build on a very reasonable budget if you are willing to study what others have done and put a little time & effort into the project.

Thanks! those links were quite helpful.

I am struggling with understanding the math behind the blower requirements. I want about a 400-800 CFM blower @ 1.2" of pressure, what does this equate to @ 0.0" of pressure? I can find blower specs, but they are mostly @0.0" of pressure.

That pic is of a standard flow hood, not a laminar flow hood.  You don't need to follow all the blower math because it uses a much more logical system and doesn't require such big blowers.

I have one like this, built it myself.

Vertical hoods work fine but the protocol is different,
plus you need to make some concessions like working with
glass hip flasks instead of petri dishes etc.

If you're hood is working properly you should have no problems and not have to change anything.

The only real difference is that you have glass in front of your face and the air only rushes past your hands, so you don't have to sit there and work like you're staring into a fan all day.

Sometimes you have to raise the front to get large things in and out, but it's well worth it for the cost savings and not having wind in your face all the time.

As RR once posted re vertical hoods, if you keep everything the same your hands will contaminate the cultures when you open them.
There are many protocols, mine (kudos to Sparkle),  allows for small mouth containers and forceps use.  No use of hands no need for gloves, virtually no contams, if you follow the protocol.
You can find this protocol in Sparkle's threads.
