It seems amazing this project, if you want a Hakko Fume extractor fa 430 in Europe you must pay over 1200$!!
So you have my support on this DIY fume extractor!!

Ill definitely upload some shares as my next iteration progresses.

Ive just now order sheet of 1/4" plexi-glass for a clients project. The remnants of that project are going to make my new upgraded box. This will make an excellent show piece as youll be able to see all the guts and glory.

Additionally, i strongly recommend using the lock-tite esd hoses. They offer articulated control and self-supporting for about 3ft. If you want them longer then you have to create a brace. All my previous builds have not incorporated these and always felt a little clunky and lack-luster.

If anyone has questions on fans, then feel free to ask. However, almost any fan will do. Just look at cfm rating of some of the commercial units like hakko (very poor/low cfm). I think Louis's recommended unit, which works very well, only has around 90cfm per fan. My target is always 120 or above. Next build is going to use two 10" fans with 300cfm each.

Also, if your really on a budget... You can use my very first build which will cost about $50. Super simple. You only need 3 items (i bought all of these of wallmart years ago)
1) portable 20" window fan
2) charcoal filter unit aka odor control filter in the ac supply section (replace as needed)
3) roll of duct tape or duck tape... Your choice

Steps to assemble the cheapy
1) align filter to intake side of fan (my preference, but either side works)
2) duct tape filter to fan at middle point of seam
3) turn fan on and enjoy the largest and most powerful fume extractor that youll ever own.

Lets start by choosing the best fans for the job. Can you post link with fan specs that would be appropriate for the the project?

Good post. I was unaware of the 3 filter components. Knew they used multistage, but again im lazy, so i never went past just straight carbon filter.

Ill do some surfing to locate, but if anyone knows or finds a good source for all filter component... Please share.

Might be possible to find some premades that have basic enough dimemsions that they can be easily used/adapted to any enclosure.

Another awesome find. I actually use the same vortex fan (made really for grown houses) as the blowers for my positive pressure room. They are loud as shit. Ill have to lool into it

Good info mnaty.
The best choice would be buying the hakko pre filter and main filter, the main one has the carbon one included at the bottom.
So the fan would be before the filters, isn't it?

One thing I know is that the air that goes in has to go out but I don't know where it goes in the fa 430

In the fa 430 the filter is before the fan. The fan is located under a seperate sealed enclosure. Maybe louis would be kind enough to share some pics. I tried to find some replacement fan parts for the unit, but appears hakko doesnt sell that.

Also, i found a supplier of hepa filters and hepa filter individual components on alibaba. Waiting for response.

$120 for a hepa filter seems crazy to me. It fiberglass paper and charcol. Prefilter is even more basic polycotton blend. If thats what it cost ok, but seems it follows the model of printers... Bend you over for refills

I agree with you.
I think probably the sensors are because of the fan speed, but I don't care about the sensors, once a month we change the pre filter like Louis does and we don't need the sensors and too many electronics.
I prefer the easiest way to do it. You can put a stick that says the date when you changed it.

Louis could you please share some pictures of the hakko fa 430?
