Topic tags/keywords: dust collector sizing

I purchased an old dust collector for $100 and I’ve hooked it up and it makes a LOT of noise and seems like it would suck the chrome off a trailer hitch. So I’d like to use this in my shop for dust collection. I know how important it is to properly size the duct runs, and it would be nice to know the cfm of this machine before i do that.

The machine is a Linmac Machinery UFC-102B. I’ve googled it and came up with nothing. The motor on it is a Jui Chun 3hp single phase 220V that turns at 3400rpm. The inlet collar is 6”. I’m going to try and attach pictures.

I’ve got very little information to go on, but I’m hoping that with the information I have, someone out there who has experience with various machines might be able to venture a guess as to the cfm of the machine, or point me to a machine that is similar enough in size to be able to use it as a guide for sizing.

I think this machine looks close


Thanks for any help you can provide.

That looks like a fairly serious DC and probably draws in the neighborhood of 2000 cfm.

If it were me, I would go with 6” ducting for the trunk(s), TS, Joiner, and Planer with smaller (4”) gated drops to your other tools.

I’ve got a pretty good setup, in that the inlet to the DC is about 6” lower than the floor of my shop. I’ve got the DC in a shed behind my shop.

I’m going to run the trunk line along the back wall of my shop along the floor and Tee off of it up to my tools, so chips will all be going downhill.

The TS is the longest distance, about 35’, with three elbows between the DC and the saw. I’ve got an outlet on the cabinet of the TS and an over-blade guard with a hookup. I haven’t figured out how I’m going to make the hookup to the guard from the floor. To make matters more complicated, my saw will be moved about 6’ towards the duct when not in use.

BTW – I think the inlet is 6”. It actually measures a bit less than 6”. I’m not sure if the trunk is supposed to go over the outside of the intlet, or the other way around. Perhaps it is made for a 5” trunk to go inside the inlet collar?

Greg…Earlier this year I bought a dust collector it is a Lobo DC-102. It looks very very close to yours, If you Google it you should find some pictures that will help you. As to your inlet…mine has a three line inlet. In other words the six inch line has an adapter that has three four inch lines coming off of it.

Have your say...
