Topic tags/keywords: dust collector

Hi all,

I have a dust collector that i bought second hand. it has a fabric bag on top and plastic bag underneath. no manual came with it. lately i feel that the suction is not as strong as it used to be. the only maintenance that i do is hitting the bag from the outside a couple of times every now and than (with the power turned off). anything else that can be done or should I replace the bag?

My DC has a couple of bars in the intake to keep wandering hands and large objects from getting into the impeller. It often gets clogged if I am sucking up long stringy shavings near the lathe.

Luckily I have a clear hose so its easy to tell if things are getting gunked up.

Do you have felt or cloth bags? If they are cloth it might be worth trying to hand wash them or a gentle cycle machine wash to see if they work better. I have felt bags and don’t think they would survive a trip through the washer.

I just beat mine out. Occasionally, when I let the chip collector over flow, and I have the bag off the dust collector, I will turn it inside out and give it a good shakeing/beating. I have felt bags and the manufacturer advises not to wash them. It will alter the texture and you’ll lose some of the filtering ability.

Thanks! I guess I’ll just show no mercy and beat the hell out of it.

I take a air hose to mine and blow it out. Just lower to pressure first. I did this yesterday and pulled almost 2 gallons of caked on dust out of the bags.

hey heres my 2 cents if you think youve lost cfm on it clean it out good but over time the empellers do where out. i dont know how old the unit is but i wore out the empellers after about ten years of use.
