Airsuck 2000A - Standardized Version of "Airsuck 2000"

thingiverse

This is a standardized version of my previous “Airsuck 2000” fan. Inlet and outlet outer diameter are now both 100mm. The motor is now moved a little inside the fan so the footprint of the ventilator is a little smaller. Also, various mounting points and aids are added for your convenience. Although the motor is inside the fan, dust and dirt *should* be no issue as the cooling air is drawn from outside through the motor into the ventilator housing. With the speed controller set at half speed and a filter in front of the fan, i measured approx. 47dB at a distance of 1m with an airflow of 130m³/h. Maximum airflow with a 60W power supply was at 250m³/h. Please take the numbers as a rough orientation with a grain of salt as i have no real experience in this field! Assembly: - follow the schematics provided b the exploded view. It will show you the placement of all parts including the optional ones. - Use a thin rubber sheet between motor and clamp to ensure having the motor in a fixed position at high power settings. Bill of material: - A 775 type motor and a power source with 12V, 60-80W - optional a speed controller for the motor - A coupling part to distribute the forces from the motor to the fan (e.g.: https://www.conrad.at/de/p/messing-kupplungs-einsatzstueck-modelcraft-modelcraft-bohrungs-5-mm-x-l-13-mm-x-15-mm-226505.html ) - self-tapping screws 3.5mm A word about print settings: - the more infill you add, the less resonance you have and so, the more quiet the ventilator will be. - Do not use support structures - everything can be printed without. Even the fan itself is constructed in a way that all gaps can be filled through bridging - If you use an advanced slicer for the rotor, you can use a larger extrusion width (0.7mm). this will work even for 0.4mm nozzles and will bring down print time from 4 hours down to 2 hours (approximately)
