Roomba dual HEPA filter 120mm

thingiverse

Re-designed and enhanced.\r\n\r\nNot intended to extract air from 3D printer enclosures. I encountered a serious issue with particles in my workshop, so this design is meant to handle high airflow and clean it; if you attempt to use a 120mm diameter for recycling or extracting air on smaller 3D printers, you may struggle to control the temperature.\r\n\r\nIncluded a universal 120mm bracket for easy mounting of whatever you prefer, regardless of fan thickness,\r\nIncluded 2 types of exhaust:\r\n-The shortest one is designed to minimize air fluctuations around the fan, resulting in higher pressure inside the filter.\r\n-The large one allows connection with 120mm ducts.\r\n\r\n\r\nRetention plate M3 screws\r\nFan joints M4 screws\r\nBracket plate M5 screws\r\nUses Roomba 800-900 series filters.\r\n\r\nThis assembly is designed to work with high-pressure 120mm fans, like top-end Ssunon or Delta models. Regular 120mm fans will function, but when a filter is present, the primary concern is the fan's pressure to prevent debris from being blown back into the system as the filter becomes clogged.\r\n\r\n\r\nUpcoming, I plan to create another design featuring two identical filters for 80mm fans, likely incorporating a coupler to stack fans in series and increase system pressure.\r\n\r\nAn 80mm low-cost fan with low pressure is sufficient for a 3D printer enclosure; the dual filter setup will provide extended time between filter replacements.\r\n\r\nJust wait a few days if you're interested in installing this on your 3D printer enclosure\r\n80mm Filter: https://www.thingiverse.com/thing:4211829\r\n80mm Butterfly valve: https://www.thingiverse.com/thing:4216080
