Air Blower

[Tracer_Bullet]

Variable speed will cost 1200-1400. I think ibell is also a good option.
Deal of the day: IBELL Air Blower EB60-69 600W, Copper Armature, 14000 RPM, Blow Rate 3.3M3/Min, with Variable Speed https://amzn.eu/d/5KHrEr4

Bought this one, damn even min speed is more than enough. Max speed is very strong ( and very loud ). This should work very well for cleaning pc (+brush), hopefully will last.
