HEPA FILTER

thingiverse

Hello, this is my first upload...wow so be kind...i've a lot to learn.:-) This is a simple hepa filter project based on karcher wd3 filters. the fan is in push configuration, so the air is forced inside the filter from the printer cabinet. I found this solution more reliable in terms of performances. Please note that this is still a work in progress, you can find and manipulate the 3d model here: https://www.tinkercad.com/things/6i8tSbAMTsI-hepa-filter-wd3/edit or search in thinkercad: Hepa filter WD3 The assembly is thought around a simple pc fan 90x28 that will be, for sure, replaced by a more powerful high pressure fan 90x38 and one karcher WD3 filter. for the new 90x38 fan you have to modify the fan recess to fit the new height. Another big improvement could be to fill the interior of the filter with a carbon filter foil for a better air cleaning especialy for whose of you like to print ABS. https://www.amazon.it/GDSTIME-Pressione-Ventola-Raffreddamento-Cuscinetto/dp/B08JP62Y3Q/ref=sr_1_1?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=OUWW82XFHVP4&keywords=ventola+alta+pressione+90+mm&qid=1644946778&s=pc&sprefix=ventola+alta+pressione+90+mm%2Ccomputers%2C74&sr=1-1 https://www.amazon.it/Cartuccia-lavabile-Karcher-A1000-A4000-K2000-K4000/dp/B09HR4J18Y/ref=sr_1_3_sspa?keywords=filtro+karcher+wd3&qid=1644946919&sr=8-3-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyMFo5UzZIQ0JWWlRaJmVuY3J5cHRlZElkPUEwMjk4NzY1MTJIRkFXOFVITVg4QiZlbmNyeXB0ZWRBZElkPUEwNjgyNDg4MUhYNFpLS0JUMDRDRCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
