Hello everyone,

I am working out placement for a new dust collector and had a question that I am not sure on. On the 1 1/2 hp units where the blower is connected to the bags by the hose is there a downside to separating them by 6-8 feet with either hose or pipe connecting them in a relatively straight line? There is one best place for the bag and the best place for the blower/sucker is on the opposite wall. In my mind I don't see a problem but as always I am sure there things I am not considering.

Thanks,

It shouldn't be a problem Burton. Especially if you stick to the full hose diameter and/or use PVC or some rigid piping.
You actually have room for a dust collection system in your tiny shop?

Hey Wade,

Yeah, I have a little 1 hp in there now but it barely keeps up. I'm hoping to mount the bag/filter part up to the ceiling in the 10 ft. high part and mount the blower on the other side, closer to the tools. Hopefully it will free up some floor space and I can squeeze my jointer in.

(we'll see if it really works.)

Hi Burton,

If you want it to work better .. you need some kind of separator (mine is a shop built one, really just a big box with a baffle that deflects the big stuff down before it can get to the impeller) .. and then ditch the top bag and get a pleated canister .. 5-6 times the air flow area of a bag, and smaller too in size, plus its easy to use the handle flapper to clean it out.

If you separate first, I see no issue really with some length to the bags/filter

Thanks Tony,

I didn't think about the separator, that makes some sense. I am definitely going to go with the wynn environmental after market filter top. The specs on those are pretty awesome, and like you said they are smaller in footprint than the bags. A win/win!

Hopefully this is relevant to Burton's query also, but please ignore this post if it is in fact a derail of the original topic but I was hoping Tony K you could share more specifics about your baffle separator. Does it work well? I was thinking of making such a thing to go inline before a cyclone, to try and capture the largest shavings for the garden, without them having too much fines mixed in (so we don't end up breathing the fine stuff after all when dumping out shavings in the garden). I haven't found much on a good design for this. Thanks!

Peace,
Sanaka

I have designed and sold several dust systems from 2 hp to 85 hp. The only thing you want to make sure of is that your NOT adding any 90deg bends straighter the better .

and when hooking up equipment , always try and stick to max 45 deg turns , the system will work better . It takes less power to pull same cfm through ( 2 ) 45 deg bends than ( 1 ) 90 . the baffel that has been mentioned is an excellent idea , as well as the canister system . they do work extremely well and will help increase cfm.

And if useing pvc pipe make sure your system is well grounded , get the crap knocked outa yourself from static electricity .

prolly havent said anything you dont already know . but hopefully i helped.

I dont have a pic, but will describe best I can ....

I bought a 4x8 sheet of 3/4 ply, and figured out the biggest box i could get out of it - at least I think it came out of one sheet .. anyway its 36x28x21 ...

on the narrow side - 21, at the top, I cut out three inlets, all blast gated - this where I select which hose - no Y connectors at all. The 2hp motor/impeller sits on its side on the box top, sucking up, and blowing sideways into a short 6 inch duct to the bag/filter. The separator/baffle drops down inside, from the top, full width and about a foot down, and about a foot inside from where the inlets are. The motor intake is directly behind this baffle, such that as material comes in, it will hit the baffle, drop down, and the air continues around to the impeller. All the insides are sealed with caulking.

I got the idea years ago from a FWW or such, and must admit, it works amazingly well .. I only get the finest of dust in the bag - no chips ever. I added two cleanouts .. one on the front of the box at the bottom, with threaded lock knobs, big enough to get a dust pan in for cleanout, and another on the side behind the baffle, to clear the impeller intake if required - amazing how many pieces of parchment paper or plastic bags get in there and need to be pulled out. As well, I added a plexi window on the front to see when its getting full ... but you will notice the suction start to drop as it gets close to the bottom of the baffle anyway. Before the post motor bag gets even half full, I will have to empty the box out many times.
