Hi all. I recently purchased a Powertech 1HP wall mount dust collector (it’s supposed to be delivered today). I went with this DC since it’s smaller as my shop is small. I plan to hook it up to a chip separator (trashcan with a fancy lid) and have a run of about 20ft or so of 4in PVC pipe with 4 wye’s on it for 4 different tools (with blast gates). The pipe will be in a straight run along the wall.

My question is… will this DC be underpowered or will it work adequately? I’m afraid to get everything hooked up and then be sorely disappointed. I plan to make the system as air tight as possible, so I’m hoping it will work well.

Does anyone have this setup? Should I plan to just send the DC back?

Thanks

That’s likely to leave alot desired. A short length of hose (<7>t very recently cleaned to allow proper airflow.

I think it will get most of the chips but you’ll
still have sweeping to do.

I have basically the same thing, only from Rockler. It works fine with a flex hose going to a single tool. I don’t know if it would work trying to draw from multiple machines though.

So I will have blast gates on all drops and keep all of them closed except for the one I am using. My straight trunk will only be about 15ft long. The drops will be with wyes and then the gate and a small piece of flex hose to the tool.

I may have to end up going to harbor freight and getting their 2HP DC. :-/

I think it is undersized for what you are doing. The HF would probably be a better choice.

Yea I’m beginning to think the same. I may send this one back and get the HF 2HP one.
Thanks

This will be way under-powered for what you are attempting. I would suggest returning and looking for something in the 2 HP range.

IDK why more people don’t build Pentz’ cyclone. It’s not really that hard.

This unit and the harbor freight both have 10” impellers. This unit has a 4” inlet and the HF has a 5”. But if you reduce the HF immediately to 4” you will have about the same performance(HF has a bigger housing and outlet). The trashcan type separator will also hurt performance, but you will need something as these very small units don’t have any separation built in. So performance wise there is your 1HP then the HF and then most any 1.5HP DC (all of which have larger impellers). None of these units were designed for ducting, but to be attached directly to a machine. The manufactures claim of 527CFM is optimistic and with no ducting or separator. Adding both of those will reduce performance to a good vacuum. Will it be ‘adequate’ sure, you will feel air through the duct. You don’t say what machines you are connecting this to and what CFM requirements they have. Most machines have a minimum of 300-400 CFM, with your setup I am guessing you will have <250 CFM at any machine. As Loren said you will get some chips.

It is hard to say what your expectations are but I think you will be disappointed.

Hope this helps, Let us know what you do.

I would agree with everyone else, 1hp isn’t enough to be happy, but I will say it’s better than nothing and the wall mount is nice.

Well, just to update folks. I decided to go with a HF 2HP dust collector. It seems to do a good job (even with the 4 different drops/blast gates). Hopefully it holds up!

Have your say...
