Good points I do plan to go 8 inch all the way to the roof pretty much a straight shot. As for the intakes I positioned my fume hood about 4 feet from the opening of my garage door I live in Texas so it's hot in the garage about 8 months out of the year I have a small shop swamp cooler I use to...

...we did get hit with that ice storm that definitly wasnt normal it does get cold but not too cold i couldnt be in my work area with a good hoodie. thats what i was thinking too with two fans both are controllable so i can turn them up or down as needed turn one or both off. ill also be...

...of the Venturi effect so I decided to go with a direct vent system and beefed up the wet scrubber design. But when I got the fan on top of the hood the exhaust was smaller than any coupler I had so I used a traffic cone as a means to connect my 10 to 6 reducer to the fan it's self I never...

I’m in Scarborough and would give you some nitric. Or bring the carb over and we could do the test in the hood. Len

They do have a fume hood and the personnel is trained, we are talking about 5 liters. Until now they have been sending it out for processing. So if you have washed the cement to pH 7after Zinc treatment, there will still be significant levels of Cyanide?

Much appreciated. I will do a ton of reading. Im not totally against DIY but I am so busy with other things that if its something I could throw a bit of money at (scrubber, hood) and to have it delivered working, id be interested what options you would suggest.

...The borax mass is still there and just as stubborn, but I'm here now and hope to learn about this whole thing from others. There is much I stil need to do to get set up semi-properly (new bench dedicated to recovery and refining, fume hood). The forum seems quite active, so I'm glad I found it!

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.

...a design but it seems to have settled on two things, both in error. One is that you will experience any longevity with a carbon filtration unit working on pass through air, and Two, you are scrubbing 100% of the air exhausting from the hood. Exactly what design parameters did you give it?

...using the cone. It's inserted in the top wye joint and pulls any excess fumes off the vacuum powered wet scrubber as well as pulls from the fume hood. I know I can now use the Venturi to save my blower but I really am not worried about it it's pretty well protected as long as the motor...

...Texas, and my wife’s dream home, a few members were given ores, concentrates, chemicals, glassware, tools, and lab equipment, including fume hood. Also, I have no clue how well your shop is set up, and do not care to. When you allude to doing something stupid, such as treating your rocks...

I DIY'd my fume hood. Ive gone through 3 in-duct fans now, because I'm too cheap to buy a proper chemical exhaust fan. I'm still without a functioning fume hood as I dont want to spend $40 on another fan, so I've been working outside on my deck for the last 6 months or so, while using gas...

This is a quick sketch using pvc and the tube tote I was planning with the fan exhaust. Injection nozzle to increase the pressure spray from 400gph sump. OK tell me if I have a clear idea of function or not and the pitfalls to this idea of a build. If tou would be so kind I mean. Please.

If he has a fume hood running in is work area corrosion wont be a problem especially if the fume hood runs 24/7 I had tools in my lab that never left the lab for 10 years & they never corroded Kurt

...the importance of maintaining a safe and efficient lab environment. Pulling air from outside the lab, preferably from a wall opposite the hood vent, can significantly enhance the effectiveness of the blower system. It's a crucial step in optimizing airflow and ensuring proper ventilation...

That I can do. I'll maybe draw up a diagram with measurements in a document that can be shared easily. It would be nice to know as I myself have yet to find the answer and believe me when I say I have been looking.

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.

This is a larger hood in a commercial refinery but it still demonstrates one basic method to allow the NOx to be collected and sent through the scrubber. These beakers have had the watch glasses removed because they were ready for the next step. The watch glass directs the fume from the pour...

Hmmm. I hadn't thought of that because I thought the entire basis to move air from the hood chamber was to use a venturi design which calls for a compression of the air to a small diameter and then to a larger. I could try it though doing it directly though. That's kind of the point at this...

I just hate it when I open a can of acid and the fume just evaporate. Or my tool, clothes touched liquid and give off the smell for days

I'll take some pictures tomorrow and post them. I have a lab hood for the fire assay but it was never used for small test lots.

Thanks - I have all ways heard them referred to & called them "totes" & have used them for "many" different things (maple sap collection/storage when cooking maple syrup - chemical waste storage/treatment - cut out tops to use as gaylords etc.) Kurt

It's a corrosion resistant PVC fan it's made for chemical fume hoods so I didn't see a reason to not have the fan directly pulling fumes there was one metal bolt and nut inside the fan that I covered in silicon. The cone I used as a coupler on my 10 to 6 reducer.

If I'm understanding the hood with the fan and suction pipe sit between the refining beaker and the naoh beaker right?

...of manufacture , guessing total age maybe 5 or so yrs. At time only working with hydrochloric acid with connector gold from fingers & pins - do not have lab , fume hood so only processing outside . I think I watched Dusan999 , did not remember till mentioned here , will watch again . Thanks

...but I don't think there are any (affordable) filters that will withstand acidic fumes for very long. You would be better served to use a fume hood.... A DIY hood can be made fairly cheap. I would also recommend your vacuum flask be heavy walled. Check with your county office and see if they...

20 minutes to say he really doesn't smell anything he considers almonds. Turns out neither does 50% of the population. The meter seems very sensitive and I wonder how much CN it will detect in a hood with decent airflow.

...thing, I was just totally overthinking it. I do thank the both of you for replying to post though. It's really helpful. Right now the hood does have air flow. I'm going to use the manometer to find the best spot (smoke test too). Then I'll take off the intake funnel and see how much it...

I love the cushioned fume hood surface. Which interior fume hood designer do you use?

When I can I always try to build instead of from the store. Most the time I get frustrated because of the poor materials used improper electrical and even saw me where they use the wrong motor type. I will be trying to start building it right away since I kind of wanna start this but I will not...
