Einhell Power X-Change Smoke Extractor
Print Profile(1)
Description
For my Einhell batteries, I have built a soldering fume extractor using a Noctua 140mm fan
In addition to the printed parts, the following are needed
- 2 spade connectors with 6.3mm width and 0.5-1.5mm² cable cross-section (red version)
- Scrap wire
- a 1203BB DC motor speed controller
- a Noctua NF-A14 PWM chromax.black.swap
- 8 wood screws 3x40mm
- 4 wood screws 3x10mm
- 4 M4x40 screws
- 4 M4x20 screws
- 8 M4 heat set inserts
- 1 threaded rod M8x140
- 1 DIN985 M8 lock nut
- 1 DIN934 M8 hex nut
- Activated carbon mat
The spade connectors, which form the battery terminals, and the cables were secured with hot glue in the lid
Wiring is straightforward. The fan is connected to the output of the motor controller, and the battery cables are connected to the input of the controller (use wire ferrules!)
The threaded rod, along with the printed handles and M8 nuts, forms a joint for adjusting the fan's tilt
The heat set inserts are melted into the housing frame. The fan, with its shroud and the long screws, is mounted on this frame. On the opposite side, the filter housing is mounted with the short screws
The rest should be easy to replicate based on the pictures
The electronics housing is screwed together with 3x40 countersunk wood screws
Warning! I have not provided any grilles at the front! Risk of injury if you stick your finger into the fan ;-)
