Hello, I picked up a Delta 1 hp 50-720 dust collector at a yard sale on Sunday. It wasn’t completely assembled and was wobbly, two casters were gone but the rest of it was there. I asked how much and if it ran. The guy plugged it in and I asked how much – he said $30 and I said ‘I’ll come back with my truck.’ I had to go to Harbor Freight and buy a box of assorted bolts and nuts and lockwashers to finish putting it together so total investment is $35. The thing had never been used and he got it in a lot of woodworking stuff from a woman who’s husband split. I know it’s not the cream of the crop but I thought for the money I couldn’t go wrong.

It has the cloth bag and I just looked at the price of the canister filters – ouch! If I put a Thien baffle on it to divert a lot of the debris will the cloth bag suffice? Also, can I divert the air outside like a dryer vent, and if so, what size piping would one need to maintain full vacuum pressure without burning up the motor?

You may have lucked out, I think that collector may have a 1 micron bag; if true it will be serviceable. As for your question about duct sizing, I didn’t follow the “vacuum pressure” part, but I think 4” duct should work just fine, the best way to tell is to check the motor amperage draw while it’s running with an amp meter.

Thanks. Yes, it is a one micron bag. Good to know I don’t have to lay out any more money at the moment.

I didn’t know if just using the same size as the inlet hose would work for an outlet. I read that maximum hose length should be 10 feet, so it’ll probably have to be wheeled to the tool or vice versa which will limit how I set it up eventually.

Adding a baffle will divert the larger chips, but it doesn’t stop the fines. That’s the job of the filter bag or canister filter. Many of us have worked for many years with a filter bag. The one micron mesh bag is a good one. You can upgrade to a finer filter canister in the future.

One horse is not a huge collector, but keep your runs short and you should get good service out of your new collector. You really did get a real steal on it.

I know – he said I was the first person in two days who even knew what it was. Also got a Shakespeare trolling motor for $10 from him. Pretty sure he had even less into those two things, but I was pretty pleased.

Have your say...
