I use a squirrel cage blower, too. All shop vacs suck the air through the motor, and a certain amount of dust gets through the filtration, and into the bearings. The water trap, is a bucket, with an air hose inlet and outlet, on the top. Water inside, catches some of the dust, in the air. I think it might work on heavier particles, but the fine stuff, still comes out.
