30" Pedestal Fan - Added 3" Locking Casters.- Harbor Freight z cheap but not cheap.
Well constructed Pedestal Fan. Spring loaded pole adjustment.. Moves alot of air at the low speed which is not that noisy. High speed (3rd chain pull) has unbelievable CFM but is pretty loud in my all concrete/CMU block garage.
Added Casters - 3" Rubber stem mounted caster with brake, #90992. Stem is 1/2" with 20 threads per inch (UNF). Get nuts and washers (reg and lock) at Lowes, Home Deopt only has the coarse thread. Drill 1/2" holes in the 4 smasdller holes already there in the base. Sandwich washers both sides, lock washer and tighten up. You will need an adjustable wrench to hold the caster while the nut is tightened. I did not have an open end wrench that was skinny enough to fit past the caster swivel bearings.
Wheels and hardware added about $40 total. Total cost for Fan $119.98 and materials, tax etc was $175. Pedestal base has a heavy weight in it so this is very stable. Very happy with fan and casters et-up, keeps air moving nicely through my garage. Easy to roll around.
Happy hunting.
