Ekasand pneumatic random orbital sanders in 5 and 6 in. round and 3 x 4 in. Air sanders are lighter than the electric equivalents and run cooler all shift, which is why shops with an air line already run keep buying them. Pick the orbit — 3/32 in. finishing or 3/16 in. cutting — and the dust handling: non-vacuum, self-generated vacuum that draws through the tool's own exhaust, or central vacuum. Hook face takes hook-and-loop discs, vinyl face takes PSA.
