Dust collector set-up questions

I have a Delta contractor's saw and just bought a Delta AP400 dust collector from a guy on CL yesterday. I set it up today and have some questions.
There is only one 4" hose that came with the system. Are people buying or building a manifold that they connect their collectors to that then feed into multiple longer and or differently-sized hoses to go to more than one piece of equipment?
Also, the collector came with two 30-micron filter bags. The seller mentioned using plastic bags on the bottom instead because they could easily be disposed of with the sawdust rather than emptying the cloth bags. Does that make sense? Also, are folks investing in finer (5-micron) bags to keep down the fine dust?
Thanks!

I tried to build my own system with the very same DC. It didn't work out well. The AP400 just doesn't have the pull to get it done (at least not what I want it to do). For now I'm wheeling mine around from tool to tool until I can save up to upgrade.
Throw away the 30 micron bags and buy some 1 or 5 micron bags.

***safety says do not do this***
There is a cross bar right before you get to the fins on the motor. If you remove this, you will greatly reduce clogging if you use it with a planer or jointer.

I removed that crossbar on one of my blowers because it was continuously clogging. After I took it out, no more clogs. Do this at your own risk though.

If you put a plastic bag on the bottom, I'm afraid you might lose CFM. Most of, if not all brand name dust collectors that I know of that have a plastic bag on the bottom also have a cartridge filter ontop. There is more filtering surface area in a cartridge then in a single bag. Finer filter bags or a cartridge filter would be alot better than the 30 micron bags you have. But don't think thats going to solve all your dust issues, a air filtration machine is also nice to have to clear the air of what escapes the DC. You will have a cleaner shop, but it's still recommended to use a good dust mask, the really, really fine stuff is whats bad for you. As far as your Contractors tablesaw goes, for dust collection you may want to read this thread http://www.woodworkingtalk.com/showthread.php?t=2188

Good information, thanks for replying. I'll definitely get some finer bags and keep an eye out for clogs--in which case I'll consider the remedy suggested. I should be okay with the crossbar gone provided I make sure the motor's stopped and unplug the unit before fishing my hand up around inside there.

I have the same DC and have it connected to 3 tools in my shop. I used 4" pvc for the main run, then neck down to the sizes I needed with other pvc fittings. I have several gates and only open the gate for the tool I'm using. The system does a great job in my shop.
