Fume Extracor For Electronics JBC Jabe integration by Artean

Fume extractor for safe soldering.
Diy version of high end fume extractors,
I'm professional on electronics and fast prototype, at same time i got my own workshop to make projects, scrap things, and fix some of them.
The correct soldering wire for reworks contains lead, and the gases of flux usually contains halogens, then its necessarily use a fume extractor with a carbon activated filter to avoid this gases damage you health.
Like a High end fume extractor, this design is composed by a main unit, it includes the filter and the fan, and a flex hose to reach the working area.
Also some High end fume extractor include secondary hoses to take fume directly from the stand. this is a great idea and is included on my design.
Each Assembly can provide a main Hose, and two stand hoses. included covers if you don't want any stand hose.
On commercial fume extractors main unit usually is placed on floor, this unit is connected by a hose to an intermediate piece whit clamps to hold on table, from this intermediate piece you have the main flex tube.
The most characteristic of this final tube is they can be blended on specific position and they hold the position himself.
On my first design i just placed the flex hose directly to the main body. i don't need 2 meters of regular hose and the clamp to the table system.
The main unit is intended to be mounted on a flat vertical surface like a wall or a table back. Right now i just designed two set of brackets to hold the main body and make "easy" the maintenance. I don't want expend more filament on a secondary clamps and brackets. if the vibrations become a problem i will include more structural points.
The main Body is composed by my Own design of line filters System,
They are designed to use 150x150mm ( Philips vacuum cleaner filters, Carbon & mechanical) & 150x160mm ( kitten box filters, only carbon), an its available two main sizes of cartridge, whit 2 shapes of filtering compound, and 6 shapes. At this time 2 shapes of kitten filters are enough to clean the fume, but i expect this configurations whit only 2 shapes has a short life time. for this reason i add the 6 shapes cartridges, whit more life time.
Files only includes the Philips Large cartridge, if you want some of the others files are on: https://www.thingiverse.com/thing:4221215/files
As a base for the flex hose i used this design making some changes: https://www.thingiverse.com/thing:3283786
Show's a perfect performance, in the strength of tube to stand in position himself, and whit no air leaks along the junctions, if your hose isn't strong enough add some tape on the inside to tight the junction.
The fan is a Delta electronics fan, 24V rated to 90W whit PWM control. it comes from industrial scrap.
To run this extractor at least you need 50W of fan power. preferably high pressure fans.
At this time i using the fan at 50% of they power and its enough to suck all fumes in front of tube, it makes an horrible noise but works perfectly, i got more vacuum power on my DIY fume extractor than a commercial ones i have at work ( cause my filter is thick and apply less flow thread down, but they life time is shorter to)
The connection box placed on the bracket takes 24V from a PSU and splits to the main fan, the Led funnel, and using a Step down provides 5V to the Arduino located on the soldering tray, also interconnects the PWM input of Fan and one of the Arduino PWM outputs.
Connectors are Molex, family's MiniFitJR and SL (701070xx)
Mostly all is designed to tap M3 and M4 Threads directly to plastic.
To perform filter maintenance is required remove one of the covers who holds the cartridge, 8 screws.
Also i started the design and test to make an 120mm exhaust noise suppressor.
This design is special designed to work whit my soldering station. and i designed an easy way to control the speed and the triggering for start working. More info: https://www.thingiverse.com/thing:4593974
Also the funnel includes a led mounting feature.
I never seen on the commercial ones, but i used to add to him, cause this kind of damn hoses usually block loot's of light on the workbench and is kind of disgusting expend 2 grands on a high end fume extractor not including a light.
