The quality of the drivetrain is the biggest factor in the performance of the sander. Pneumatic motors are low-cost to produce, so the drivetrain can be very high quality while keeping the price of the tool low.Why do air sanders work so much better than electric? Do they run at a higher RPM?
Which sander? Good sanders are that loud.. Professional shops usually don't run a dust hose. I know a pro shop that does, but he's not high production.Funny how people's preferences differ.
From no sander to an air sander, to talking about 2 compressors (that's a new one on me BTW).
My air sander is the LAST sander I would want to use for ww'ing. All that noise, and 2 hoses to contend with, and compressor running and dust extractor running.
BTDT, makes me feel like I'm working in a tire shop! LOL.
