Airsuck 2000 - Standardized Version

Updated 05/2024: Some fixes, new rotor for extruder feeder as coupler. Also added part variants for a half height version.
All Parts are interchangeable with the old version.

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 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 12-24V, 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 )
  As a replacement for the Conrad part you can use a matching extruder feeder as used for 3D printers -> outer diameter 11mm, inner diameter 5mm - depending on your specific motor). -> use the alternate rotor provided in the files section
• 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 rotor 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)
