Hey all – about 7 months ago i picked up a dust collector from harbor freight. the first thing i did was swap out the 5 micron back for a 1 micron bag. it worked super well. this thing was so powerful that i literally could not get the hose near anything or it would get sucked into the fan. no joke, i got within 6 inches of a 2×4 and it sucked it into the hose.
question 1: so 7 monthly later the suction has really dropped. i can almost put the hose directly over a pair of gloves and they won’t suck them up. i recently took the bag outside and shook out. it really didn’t improve the suction so i vacuumed out the inside with my shop vac. it still didn’t really improve the suction. the filter bag i bought was the cheapest one i could find from sears. is it possible that they eventually go bad to the point that you can’t re-use them?
question 2: the dust collector came with a Y separator so i connected an adapter so i could run a dust extractor hose (35mm) to exhaust pipe of my miter saw. there is almost no suction coming from the hose even if i block the other hose coming from the Y. based on restricting the pipe shouldn’t the suction increase?
