The instructable illustrates steps needed to strip and clean the internal parts of the Dyson AM07 bladeless fan, specifically the parts exposed to the airflow that are frequently coated and clogged with dust, greatly reducing the performance and efficiency of the fan, as well as making it noisier.
T8 Torx screwdriver (star)
Prying tool, or alternatively a flathead screwdriver
Optional T10/T12 torx screwdriver
Step 1: Remove Ring
Remove the coanda effect ring by turning it counter-clockwise holding the base securely, and lifting it.
As the ring is ultrasonicaly welded, it is not possible to open in further without permanently damaging it.
Clean by rinsing the ring well by spraying a jet of water THROUGH THE AIR OUTLET SLIT, to avoid clogging the air outlet holes.
Step 2: Remove Outer Retainer
Unscrew the single T8 torx screw.
Gently pry the snap lock nearest to the screw and lift up the retainer.
The entire motor-turbine assembly can now be lifted off the housing.
Step 3: Dissassemble Blower Assembly
Unscrew the FOUR torx screws on top of the stator. the assembly should open with ease. (no snap-fit locks).
Vacuum and clean away any visible dirt.
Step 4: Clean the Rotating Impeller
Clean the rotating impeller. One way to do this is to draw a soft cloth / wet tissue through each channel with the aid of a screwdriver. Take care not to scratch or damage the impeller in the process.
For an alternate cleaning method, the impeller can be detached from the motor by further disassembling the assembly from the back, by unscreing the FOUR bigger torx screws on top of the stator, exposing the motor. The impeller can then be washed free of dirt easily.
Step 5: Clean the Housing and Intake Holes
Remove the retainer ring for ease of work by slightly prying the three visible snap locks and lifting up the ring at an angle.
Remove the bottom sponge and clean any visible dirt inside the housing with the aid of a vacuum cleaner.
A bristle brush coupled with a vacuum cleaner will be an effective way of cleaning the air intake holes.
Step 6: Assemble Back Components (Work in Progress)
Assemble all components the same way they were disassembled. Be sure to ensure they are properly aligned. Most components are designed to fit in only one way, and any misalignment is noticeable.
There would not be need to force any components. If you find something needs to be forced in place, do check alignment of all the previous parts again.
* the motor assembly sits on three spring loaded pins that sit on the white circular ring in the previous step. ensure it is properly aligned and seated.
