CARBON FILTER FOR VENTILATION VVV Model Cetak 3D

collapsible filter for air filtration , installation in a 150 mm pipe with a 150 mm duct fan , installed vertically , the system is made for air filtration in a room where ventilation cannot be installed , coal is changed every half a year , the filter is pressed with a plate using m4 bolts , for 3D printing made of plastic , the printing area is suitable for most stationary printers .you can also print it from resin , which will be faster and ***ter . two sets of stl under FMD b SLM,SLA printing , resin samples are made .like the holes ,
I made myself out of resin that is washed off in water at a layer thickness of 0.1 mm for 6 seconds illumination per layer . it took one jar of resin and 22 hours of growth of 5 parts for everything . the m 4 screws are quietly screwed in without nuts , cutting the thread in the plastic themselves , which is enough to fix the upper pressure plate ....the installation copes perfectly with odors from a photopolymer printer in an enclosed space of 2-3 square meters , an excellent option for home use if it is not possible to conduct ventilation with a tap to the street , and it is able to simply clean the air in the room .
