I just bought a Grizzly G0548Z Dust collector, 220v, 2hp, 1,700 cfm with 1 micron canister filter. Up to this point I have been getting by (barely) with a shop vac / Dust Deputy combination, so I am essentially starting from scratch.

I will be actively researching this forum and elsewhere, but wanted to post in the event someone had a few moments to share their personal knowledge, particularly in regard to design, tips, what and where to buy (specific recommendations are appreciated). Cost is a concern and I have seriously busted my woodworking budget this year, though I do appreciate quality too.

My woodworking ‘wall’ consists of the following:
Laguna 18BX Bandsaw
Craftsman 10” Radial Arm Saw
Dewalt DW735 Planer
Grizzly G0490 8” Jointer
Grizzly G0548Z Dust Collector

My workbench / assembly table consists of the following:
Rockwell 10” Table Saw (with gravity fed dust collection bag affixed below).
Drop down area that I use for my Ridgid Oscillating Spindle / Belt Sander, Portable Router Table and Scroll Saw.

I will generally only work one machine at a time, though there may be times I go back and forth between a couple machines and it could be convenient to leave two blast gates open at the same time.

The DC has the option of a single 6” inlet or a triple 4” inlet adapter. Initially I thought a 6” PVC pipe along the base of the wall with 4” inlets & blast gates at each machine would be a nice set-up, but locating affordable 6” pipe seems to be a problem. Another option would be to use the adapter and run two less expnsive 4” PVC pipes down the wall with Wye adapters / blast gates at the machines. I am kind’a partial to PVC, but can consider metal too. Pros / cons for each design and material?

The BS is in a fixed position and has two dust ports that are currently wyed together via 4” hose.

The RAS is in a fixed position and I plan on building a dust collection box / hood at the rear of the unit and connecting a 4” hose.

The Planer is on casters and can be moved during use and I plan on using flexible 4” hose.

The Jointer is on casters and can be moved for use with longer boards and I plan on using flexible 4” hose.

For the table saw, my thought is to replace the bag with a collection box / adapter and connect it to the main collection line via a 4” flexible hose so it can be stored out of the way when not in use. I would like to get an upgraded table saw in the extended future.

For the sander, router table & scroll saw, the shop vac / Dust Deputy combo seems to work well and I may stay with that, though I am also contemplating the option of using a wye to the table saw hose and running a 2-1/2” hose to the smaller equipment.

The switch for the DC is located in an inconvenient spot, so my plan is to reloate the switch to a spot in my main work area where it can be easily reached. While not in the budget at the present, I would like to eventually add a cyclone before the DC.

Also, 1,700 cfm can be a lot of air (particularly if only one 4” line would be in use) so any input in regard to this can be appreciated – using only one line at a time, having two blast gates open or partially open, etc.

Thank you in advance for any input you would like to share.

Your DC is similar to mine, I have bag system for now with an upgrade planned.

I used “6 pvc drain pipe for the runs. The pipe was affordable but the fitting are money and you will need to plan carefully.

I never planned for using the 4” fitting at the DC. Using the larger size will provide increased flow and better removal of the chips and fine material. Plan for a separator, cyclone or Thien will work fine. I have a Thien just before the DC and have a trash can for the table saw which also connects to the planner & joiner when in use.

The system runs above the rafters and branches to the drops. Once the 6” drops down, I switch to a 4”, then blast gate and 4” flex hose to the tool. Given your layout, consider several 6” drops which then switch to 4” with blast gates at the tools. This will control the airflow.

Do a search for dust collection on this forum, lots of other ideas already posted.

Just remember once this project sucks, you have achieved success..

This site has helped me a bunch
There is a bit of a religious fervor to the site, but informative none the less
I am in the process of installing my cyclone. Went with 6” pvc drain pipe. Look for an irrigation store. Fowlers covers much of the NW part of the country. I am going to enlarge the access on most of my machines to 6” for air flow purposes.

Do not worry about 1700 cfm because it will never get there. Real cfm is in the 700-800 range. Too bad mfg list unrealistic ratings.

Have your say...
