I did everything you’re talking about a couple of years ago. My unit is an older single stage 2hp Grizzly located in a corner of the shop. I have two short pvc runs down the two walls from the corner, with 3 blast gates located on each run to allow isolation to one machine. Off of the gates are flex hoses to each machine. I used dust right connectors on the table saw, router table and jointer. The reason for the table saw is to allow me to move the flex hose from the saw to the router table that is built into the saw wing. Never run the saw and router at the same time anyway. I added a dust right port to the jointer to allow me to move my jointer out from the wall in my small shop for long boards. I found the table saw hose was better positioned when I needed to do that, so I added an extra dust right port to the jointer. I have 3 ports and one dust right handle in my shop. The rest of the machines are hooked up with regular hose clamps.
I upgraded the dust collector with a Wynn upgrade kit. It included the 15 Merv filter, mounting hardware, and two clear lower bags. It hooked up to my machine with no modifications. To help prevent clogging of the filter, I made a Thien baffle. I went that route due to limited space for a separate trash can separator in my small shop. The baffle is easy to make and you can find plans on the internet. Fine Woodworking did an article on this upgrade method a few years ago.
The baffle does work with the help of periodic maintenance. Occasionally I will reverse the hose on my shop vac and blow through the filter from the outside. That dislodges the dust from the pleats. Allow the dust to settle for 15 minutes onto the Thien baffle and then turn on the dust collector for 30 seconds and it all ends up in the lower bag. You can use the air compressor to blow through the filter also.
I purchased the Wynn filter with the removable end cap, in case I needed to gain access to the filter for cleaning from the inside. Theory was that I could clean the filter without full removal. I have not found a need to take off the end cap yet, but it’s a nice option.
The upgrade made a big difference in the basement. It was important not only for health reasons, but also the shop is in a finished basement, next to a home theater area.
