yes you can use brush and air pressure but I believe you would do better
with long hose and good vacuum cleaner and no brush

I have an apt bldg that needs some dryer ducts cleaned.
I was told by one company they used high pressure, didn't say how much
pressure, air to
blow out the duct (some are 20 ft) I have never heard of
that....how much pressure would they use?
Seems like a rotating brush would be better
