I’m new to the dust collector concept, and I’m a big fan already. I’m still goofing around with proof-of-concept with great results. My criteria is not chip collection, it’s the nasal reaction I get when working with phenolic (MDF) which all but disappeared after DC experimentation!
The proof-of-concept was put the dust collector next to the tablesaw with a 4” hose. Now I’ve picked up the 6” plumbing, refurbished the table router, and need to permanently place the DC.
I have a penn industries 2HP DC, 12” impeller, 1 micron filter.
I’ve got two options:
Option #1: Place the DC in a triangle between the table saw and the table router, these are the #1 dust producers in my shop. The DC takes up lots of room, but the plumbing is nil. A single 10’ 6” hose which gets connected via quick release to each tool when needed. done. I don’t like this option because it displaced my bandsaw to get placed in this location. Takes up valuable wall space. Only two benefits is the wiring is done and the pipe length is basically nothing.
Option #2: I am building a shed in my backyard, attached to the shop. I’m playing with a design that adds a 2’x3’ section capable of being insulated, this could contain the DC (for the record, I’m already planning on moving my compressor to an adjacent 2’x2’ shed compartment, also sound insulated. The benefits are two fold. This DC is pretty darn quiet, but this would entirely eliminate the noise. The second benefit, is that any fine dust collection that DOES happen and seeps through the filter, is exhausted out of my shop entirely. I do not have a furnace or any other carbon monoxide concerns. The big big negative is it places the DC about 30 feet away by ductwork. The duct would be all DWV hard pipe at 6” diameter, with an exit port located where the DC is now (triangle w/ TS and router), again hooked up one at a time using flex pipe.
So, I understand that flex pipe, due to frictional wall losses, acts like an equivalent hard pipe of greater length. I’ve heard by as much as a factor of 3. So adding 30 feet of hard pipe to 10 feet of flex seems like it would double the conductance from the DC? I’m concerned about losing fine dust collection. I don’t mind sweeping chips, but I’m definitely getting sensitized to fine particles.
So if it were YOU, what would you be thinking? short conductance vs get-the-dc-out-of-the-shop? Think the risk poses no real loss in fine dust collection?
