How to remove the fan blade ?
080204 FixUp EQ air blog remarks
To remove fan blade you need to obtain a thin strong probe, such as a
Scratch Awl for wood, that will fit without binding, into the cruciform
spaces around the plastic collar. Gently insert into space of plastic
collar and lever against the spring metal retaining clamp; getting
started may require a bit of force, so be careful to adjust and gauge
your efforts. The process is to move clamp in small increments, one
side then the other, up the collar until clamp is free to remove.
The collar will still be tight, so if you can form your hands into a
gear puller form with your finger tips between the fan blades under to
the solid portion of the fan ring, pushing thumbs against the Spindle
and lifting in as quick a jerk as you can manage to get it moving. Once
moving it should be removed easily enough.
The electric motors have two bearing surfaces, one front one back. Both need to be addressed.
I like Breakfree or similar that acts like minor solvent / major
lubricator with good thermal properties. The solvent aspect helps clean
out unwanted particles and/or old dried lube. The new lubrication is
heavy enough to hold up for at least a year; so yearly checking should
On other brands with heavier motors, I've tried greases when I've
stripped down the motors even further. So far I've discovered a heavier
lube can be hard on start up and need more time at slower speeds until
unit warms up.
Something like WD40 is good for penetration and flushing, but IMO too
light for sustained duty. There is a lot of spinning and heat over a
I just torn down a couple of F1's. They've been doing well for a couple
of years. But with all air filters/ purifiers, they REQUIRE periodic
maintenance. [Had my biggest laugh reading complaints about Oreck air
filters; people NEVER cleaned them and complained when they failed.]
Yes, all these small electrical motors will eventually need
lubrication, I recommend before 2 years, as one of mine had a frozen
(lack of lube) motor in that time.
If you get into the back to try to get at the rear bearing, you may
find that you might be considering a more thorough cleaning (I noticed
a bit of corrosion). If you do and if that means taking more stuff
apart to clean, be well advised of the time involved and the number of
wires needing displacement, especially the electronic wire connectors
at the front to the circuit board.
So, get a digital camera and take clear pictures (and check them!)
Before and During take apart as well as a couple of paper notes about
wire runs and placement. I have even used paint pens to letter/number
info to the unit.
