Máy hút khói hàn HEPA đơn giản

Ok, Ok, I know solder is not the best for your health. So for the new year I decided to build a fume extractor with a real HEPA filer -not some carbon filer- because this is for my health.

Printing

  All the parts can be printed on any printer with a build volume larger than 150x170x50. This means even the Prusa Mini will do!

  I recommend using PETg to print all the parts, but PLA will work. 

Building

I designed this extractor with the following components in mind: 

• A 5 inch HEPA filter, like this one from Amazon: https://www.amazon.com/Hunter-F1715HE5-Filter-Purifier-HT1715/dp/B07C9QZNFK/ref=sr_1_5?keywords=5+inch+hepa+filter&sr=8-5
• A 120mm fan. I used a 120 volt EC fan for efficiency, like this one:  https://www.amazon.com/Wathai-Industrial-Bearing-Brushless-Cooling/dp/B07SH42DCD/ref=sr_1_3?keywords=120%2Bvolt%2Bfan%2B120mm&sr=8-3&th=1 

Required Hardware:

• 5x M3 lock nuts
• 4x M3x40 bolts
• 1x M3x20 bolt

Editing

  This file was designed in Onshape, so if you would like to make changes to the model, here is the original Onshape page: https://cad.onshape.com/documents/0e0cba06d7d33acd871e47b3/w/a6ad114fc9812a7adc5beca4/e/f1791ccc2e663853ef84bff4

  Also, I've included the .step file for other CAD workflows.

DISCLAMER:

  I have made every effort to make this system as affective as I can. Though I simply can NOT guarantee this extractor with remove all the dangerous particles from the air!  Use this system with your own discernment!!
