Please note this disclaimer:
This is a quite large fan with blades rotating at high speed! Act responsible, wear safety equipment and don't give it to small children to play with! I have warned you!
Motivation: I was not really content with the built-in fan of my Wiltec spay booth (HS-E420DC) so i designed this large radial fan as a replacement.
The spray booth is also available from other resellers and looks like this: https://www.wiltec.de/airbrush-komplett-set-absauganlage-fur-farbnebel-mit-aussenluft.html
The fan is designed for high airflow at an acceptable sound level.
For a successful build you need
Choose on of the 2 FAN options:
*added 2018/10/26: INPUT MUFFLER-DEFLECTOR: Intended to be screwed in front of the air intake - directly behind the filter. Add some sound isolationg material into the recess to further quiescence the air intake
*Just a hint: Using a motor controller enables you to adapt the speed of the fan. A device like this worked perfect for me: https://www.amazon.com/Motor-Speed-Control-Controller-10V-50V/dp/B01LZAXWCO/ref=sr_1_23?ie=UTF8&qid=1540932616&sr=8-23
Although this design was made with a specific purpose in mind, you are welcome to use the fan for an other high airflow application. In this case, the following parts are not mandatory (the fan will work without them):
- Large Radial Fan - ORIGINAL FAN REPLACEMENT
- Large Radial Fan - INLET ADAPTER
- Large Radial Fan - OUTLET ADAPTER
- Large Radial Fan - 775 MOTOR HOUSING
BTW: The pipe diameter of the fan inlet and of the outlet adapter is 100mm
0,3 mm (0,2mm for the fan itself)
Assembly should be pretty straightforward. Detailed explanations are TBD as soon as i have some time left
