A gallery of home built hoods and fume scrubbers _hood_

[4metals]

Starting this thread as a photo gallery, minimal chat, of members home built refining hoods and fume scrubbers.

A quick google search brought up quite a few ideas. here

_hood_

I have not had the space to use these plans yet.
And you would have to substitute some materials for modern alternatives.
But I think the old wooden cupboards were classy.

Just wondering how the electrical outlets hold up in a corrosive atmosphere. Also, as discussed earlier, how about possibly nitrating the cellulose in the wood? Other then that, I agree, a very presentable hood.

While the fume hood seems to be the easy build, the scrubbers deserve equal attention.

Judging by the response of our members on this, apparently there more backyard in the wind refiners than there are hobby refiners with some sort of safe setup. Maybe everyones on vacation.

You really would not want any electrical plug in the hood itself.
What I have in mine is a hole I can pass leads through that can be plugged into a four-way.
A negative air pressure means it does not need to be sealed.
I have all my complicated electronics such as the power supply for the silver cell in an adjacent shed and pass the wiring through the wall.
Very important to separate sensitive equipment from your main workspace whenever possible.

silicone over all - seems to be a pain in the rear to remove for everything escrap related

Here is a picture of my very first “hood”, it lasted longer than I thought. Cannot find any pictures of it completed.

Was that a Rubbermaid trash can shed? I've always thought they would make a good starter hood.

It was used to store yard tools in when I got it. Seemed a bit small for much more than a 20 gallon or so garbage can. Maybe two cans at a time.

what's missing in the photo is the standard American reference for size, also known as a beer can!

Best I remember it was just over waist high. Maybe 3 to 3 1/2 feet high. 20 to 24 inch’s deep front to back. About 3 foot wide.
It only opened from the top and had 5 or 6 long water hoses stored in it when I got it. I cut the front opening and attached pvc inside to act as a window frame. This way I used a sheet of plexiglass for the door and could slide it up and down to adjust for air flow and a work opening. Originally it went it straight up like a chimney. Eventually, as I learned more, I changed it to come out high in the back and turned up at a 45 degree angle that lead into an upright pipe that could catch any moisture in a trap at the bottom. Similar to a sideways T. It also had a rain guard type cover I made to avoid any incoming water due to weather. It was plastic so care was needed to not over heat it. It worked well until we moved to the new place a few years ago. All this was done sometime around 2013 or so.

Here's the inside of my hood with the scrubber I am using. Hood is 48in x 30x32. The tray in the bottom is disposable and replaceable. The hood is made from Melamine and I built it myself.

Very impressive and Clean
If it is possible can you post a picture of the tray that You use it.

I will like to use that tray,in my next fume hood
because is a great idea.
Thank You for posting

That picture must be when it was newly built.... I don't see any silver nitrate or hydrochloric splatter staining........ yet.

I've been using mine since 2018 and it looks like a modern art painting ...

Mahogany frame.
PVC lined.
Plexi glass sliding sash.
12 feet of LED ribbon crudely taped around the border of the sash for lighting all round.
Not pretty but works for me.

little video of home-made hood vent. made from simple 2x4 lumber, OSB, flex seal, lites, fan speed control, etc. love it! just need to finish with front roll-up plexi-glass cover and shelving doors.

 

[eaglekeeper]

Awesome....

Those steel rods and clamps will, over time require constant attention. Hydrochloric fumes are pretty relentless on any metal anywhere near it. I have to keep my lab stands out of the lab until I need them when (rarely) distilling nitric. I did make an oak wooden stand I keep in the hood for basic filtering.

 

[CrystAG]

They are feeling it, but i suppose most lab hardware has a shelf life when we ask it to work around the chemicals we use.

I like @AuggieDog setup with the ported flask bungs. Takes up a little more real estate but i coudl get rid of the clamps.

 

[4metals]

Either of the small scrubbers where the fume passes from vessel to vessel are easily placed outside the hood with a small tube coming in to vent the reaction.

You will shortly realize the real estate inside your processing hood is in reality precious too!
