I got a smaller but similar fume extractor a while back, I should have bought one years ago. I can solder at the coffee table while watching TV without the lady complaining about the smell. I can also get in close to something where I need to see it up close and not have the smoke going right in my face.

I don't know why the name brand extractors are so expensive, they're not exactly high tech. The hose and funnel are the hardest part to build, the rest is just a fan in a box with a charcoal filter.

I am looking to go the DIY route. Probably cost me the same in components, but save me a fortune in shipping if I get most of the large parts on Amazon.

The one thing I can't find is the semi-rigid tubing, similar to the one on the fume extractor in the video. My college uses a flexible tubing with what seems like wire sprial. The one in the video seems like many plastic parts friction fit together.

Does anyone know where I can find an inexpensive one? Maybe I am just searching for the wrong name?

Thats exactly what is in the video! It's very expensive though... Any chance you know an less expensive alternative?

What static pressure would I need for 1.5m of 75mm tubing?

cleaning that hose is fucking vile

they don't sell the tool for that hose either, like they do for smaller hoses, and it does not come apart easy after a while. Best luck is to bend it into a ultrasonic cleaner into segments and push it through at different angles. I did it once and I was seething. Talk about wrestling with a snake.

dave jones is sure on a indoor air quality kick.

Surely some of the technically more gifted among us can come up with a cost effective design for a filtration system ? For Gods sake, the HEPA filter for the Hakko FA-430 is $320 AUD It's a filter with a charcoal section added how the hell can it cost that much. Highway robbery  :)

I will pretty well guarantee that the Aliexpress seller will never get back to Dave with a link and cost of replacement filters but I hope that I am wrong. At least on Ebay there is a good submission system to ask sellers questions.

Definitely interested once I know if replacement filters and subsequent costs are.

I'd be interested in purchasing the filters and making my own.

I found one basically the same for a little less on Ali Express, but no wheels.

https://www.aliexpress.com/item/33041102828.html

Looks like you buy the filters in 3 separate parts.

Just looking at second hand Pace units. Crazy prices for the presumably main filter $280 n-$450 AUD OUCH  :palm:

Off topic but Hey @Fungus, do you by chance frequent the Arduino forum ? Sorry @Inflex :)

You're killing me --- you knew I'd see that.

(Almost as bad as the prices on those filters, but I suppose it's cheaper than a new set of lungs)

I know I am a bad man :) Hey I get the disdain that you have for that unmentionable Micro controller system. I have read up a bit about how inefficient it is compared to the real nuts & bolts instructions to the controller.  I get it but also I get that said system has opened up using micros to people who would never have given it a try if it hadn't been for said system. We shall never mention this again :) Honest  |O. Three words Direct port manipulation

Hi all,

Looking at Dave's video tear down, the centrifugal (squirrel cage) fan/blower appears to have an external brushless DC motor (5-wire). The controller board looks like it could be a stepper motor...not sure.

As Dave pointed out it's unmarked with only a S/N that looks like a date stamp.

I've searched the usual suspects, ebay, Alibaba, etc, but I cannot find anything remotely similar. The only centrifugal fans I've found are larger with the motor mounted inside the squirrel cage.
 
Does anyone know where to buy this type of fan?

Surely the fan is not exclusive to Kingsom?

Cheers

Hi guys! I purchased this fume extractor on AliExpress, and it sucks like a champ, but it's quite loud. I put the sound meter on my desk, and it shows 70 db instead of the 55 db specified. Any suggestions on a quieter fume extractor? Of course, it'd be important to also measure the vacuum, otherwise I may end up with a quieter but less powerful fume extractor. I don't know how to measure the vacuum.

A few of these variants are showing up on Amazon (US) now. Has anyone had any luck sourcing the replacement filters? It seems like all of these AliExpress xx-180 models recommend 3 months between filter changes, although I'm sure the filters would last at least year with more casual use.

I think that is the problem with these cheaper units - you cannot get replacement filters for them. I got sick of procrastinating about getting a decent fume extractor so I bit the bullet and got the Quick 6601. Filters are available at a reasonable price and cheaper than the Hakko or Weller. I am in the middle of reorganising my work space so I haven't used it yet but am confident it will suit my needs (touch wood) https://www.ebay.com.au/itm/164445553953

The Quick 6601 looks like a good option. Unless filters for the cheaper units start to become available, the Hakko FA430 is starting to look like a better option again. You can get those filters next-day from DigiKey whenever you need them.

Companies like Kingsom have to sell filter packs, they would be crazy to not sell replacement filters. I guess they just haven't made their way to AliExpress yet.

Edit:
I did some more digging and found what looks like a re-brand of the KS-180 on Amazon, the XF-180. The listing has the "main filter" for $100, but it doesn't seem to have the other two filters: https://www.amazon.com/BAOSHISHAN-Absorber-Extractor-Soldering-Workbench/dp/B081DLN7RF

Bit of an update. Kingsom got back to me, filters are available and cheap. They quoted around $42 USD for a full set of the pre/mid/main filters. If you're comfortable buying direct then theKS-180 still seems like a good option.

There's no links, you'll need to contact Kingsom using the same Alibaba link Dave posted in the OP and deal with them diretly, at least until someone starts importing them to your region.

Before you buy any of high-end solder fume extractor or even low end
ask the manufacturer of it about does it remove lead gas ?! because i have some doubts about that !

for past few year ive experimenting with soldering air filtration i started from can-lite filters
after some time i was understand about activated carbon itself is not enough to remove most of smallest gas particles generated during soldering
these include:
-formaldehyde ethyl acids phenol gas and many others included in soldering flux
-lead (pb) gas

To clean air from these smallest particles this commerciall fume extractors use usually standard activated carbon mixed with impregnated carbons or activated alumina balls - they threat them with potassium permanganate which is in short kmno4 media

the kmno4 convert smallest particles to largest (oxidise them) and finally these largest particles are easy absordable by rest of non impragnated activated carbon which is suitable only for large particles such as odours (in this setup formaldehyde and other are oxidised to odours)

Some of solder fume extractors use catalitic activated carbon or carbon impregnated by potassium iodide or molecular sieves

but the main pit hole in gas stage filtration is about - does these impregnated media could remove lead gas ?! in short i have some doubts about this and i didnt make yet more experiments coz maybe potassium permanganate could oxidise lead

I didnt find reveal informations about lead (pb) gas stage filtration in google so i guessing is hard to remove it from air stream

there exist some speciallised carbons impregnated by for example elemental sulfur to remove mercury from air stream
the mercury is one of heavy metal too but maybe for lead need another media

Usually fume extractors companies doesnt inform you about about what exactly you paying for , they just inform about they units can successfuly remove dust microparticles (hepa + prefilters) which is just part of particles called dust , but totally zero informations about gas media type in use and whats they exactly cleaning from air !

We can compare there another air filters home humidiffiers - they allways inform you about what kind of gas filtration media they use - does i dont have right ?! some of them use just coconut activated carbon which some others use potassium permagnate media and some others use molecular sieves but they allways let you know about for what you exactly paying for !

In short i think any of these solder fume extractors doesnt remove lead gas :( and if you are hobbyst for sure you wont soldering with lead free tin then would be uselless to buying them

Certain usefull informations which i collected about these solder fume extractors and believe me it wasnt easy to find them !

Chinese solder fume extractors type Quick 6101A + some of they clones such as WATERUN F6002D use catalitic activated carbon

High end solder fume extractors such as BOFA V200 250 300 and Weller zero smog use potassium permanganate

I also sended emails to few of these solder fume extractors companies about does they filters remove lead gas ? and only 1 answer ive received from JBC company which is partially missleadded

quote

Good morning Lukas,

 

JBC fume extractor can protect you of the solder fumes, either leaded or lead-free.

 

However, complete protection in lead soldering is possible only if you follow Safety Data Sheet of solder lead wire producer,

Good ventilation in the office, eye protection, protective clothing….

FAE has 3 filters, according to mentioned standards below:

Medium dust filter M5 (EN 779)

H13 particle filter (EN 1822)

Activated carbon filter

He wrote answer about dust prefilter + hepa filtration stage except gas

Another misleaded information i found on hakko website about lead gas ;)

https://hakkousa.com/lead-free/

(20) Will the Hakko HJ3100 extract lead fumes?

There is not, and never has been, a need to extract 'lead fumes' from the air while soldering. The smoke is a by-product of partial combustion of the soldering flux. No more. No less. Lead does not vaporize at soldering temperatures.

This information is 20 year old and is totally bullshit ! and offcourse there you have trully answer about just one from many solder fume extractors type hakko about it doesnt remove lead gas ;)

Any informations there about lead (pb) gas filtration stage removal are welcome , also more informations about these fume extractors which could help us to choose right one , they are expensiff and you never know about whats you exactly paying for until you buy them !

And btw. if you didnt know the symptoms of metallic taste in mouth fevers memory loss problems with concentrations you getting from lead gas only ! (not from lead dust microparticles which can be easy cleaned by hepa filters)

I did many experiments in past with custom made carbon filters ive never uses hepa just MERV 14 class dust filters and when i apply more carbon or slowing down air outlet (excedded time contact with carbon) then i reduce more more % of lead gas which cause these health problems (activated carbon could remove lead gas but just a small %) so here you have answer hepa isnt important for lead removal but gas media

Another informations found in google

A novel discovery is that KMnO 4 can facilitate HMO removing heavy metal. The results showed that residual Pb(II), Ni(II) and Cd(II) in pH ∼8 were 0.01 mg/L, 0.02 mg/L and 0.05 mg/L after depth reaction, respectively. The mechanism of oxidation of Pb(II) in alkaline solution by KMnO 4 with HMO catalyst was studied. The XPS results demonstrated that HMO improved oxidation efficiency of KMnO 4and the products Pb(IV) content increased by 50 percent approximately. The mechanism of Ni(II) removal was similar to Pb(II). Cd(II) could be absorbed but not be oxidized, while KMnO 4 accelerated Cd(II) removal effect of HMO as well. KMnO 4 promotion was still existing in the acidic conditions, which showed KMnO 4 could promote HMO adsorption of heavy metal, and reaction mechanism is required for further study.

Ive kmno4 alumina balls in basement soon i shake them with activated carbon and do test and let you know !

Unless you set your iron way to hot the lead won't boil and thus emit no gas. Also you are supposed to solder mostly lead-free nowadays. IOW: having lead gas (and tin gas as well) in the soldering fumes is highly unlikely to put it mildly.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
