Try putting in a pre-screen that can be easily removed. That'll catch the big stuff and save the bagging for the fine stuff.
Get a tube that fits the hose and put in a cone shaped 1/8" hardware
wire. If it plugs up you pull of that section of hose, pull out the cone, dump it, put it back and your back in business. Similar to a strainer in a water
With a planer
you would need a pre-barrel. Chips going in the middle and the air going out the top hose into the bagging system, with a screen
in the middle.
For industrial sand blasters there is a system with two barrels, one stacked on top of the other. Between them there is a cloth/filter bag with a weight attached to the closed end.
When the vac is turned on it inflates the lower drum at it's upper section, raising the bag up into the upper drum and allowing the air to escape out filtered vents and collects the particles.
When the vac is turned off the weight causes the bag to fall, dumping the dust in the bottom of the lower barrel. Which creates a self-cleaning bag.
I had to add a pre-screen to this system because the guys were sandblasting gasket
material form off of valves & flanges plugging up the bag.
