Some central vacuums (CVs) power units have no bag, whether it's because it's cyclonic or it's "self cleaning filter" or some other concoction.
I think we can all agree that most vacuums with out a bag equals a messy job cleaning the dirt container AND possibly even messier job of cleaning the filters.
I've read numerous posts about people changing out their power unit not because the motor wasn't good or the suction wasn't good but because they didn't like the mess. I just wanted to share my experience of adapting one type of CV unit to using an easy to change paper bag. Perhaps this can help someone.
I bought this NEW (old stock) 2007ish DustCare DCC4 floor model CV in Oct. 2017 but didn't need it right away. It has a bypass motor and was a "self cleaning filter" type set up. I recently found an MD model I like even better than this Dust Care and have since sold this one.
I simply pulled out the filter that was at the gray foam level and was held in place with a tension wire. I removed the utility valve and put a cap over the hole on the front, then took a few CV plumbing pieces and glued them to the (darker white) original inlet. see pictures.
The way it is now, one simply drops the bucket that hangs from the bottom of the machine and slide a new bag on the angled pipe, then replace the base. When it's full, just do the opposite.
CV bags are generic and not expensive. It sure saves a lot of hassle and mess.
Some manufacturers such as beam and electrolux provide adapters to do something similar to what you did. I have a beam unit that was originally similar to the Dustcare design, emptying it was awful, I got the bag conversion kit and it works great. Yes, there are only a few kinds of central vacuum bags, the main difference is whether the cardboard intake is at the top of the bag or more towards the middle. Other than that they are pretty much all the same.

Technically, as long as the base of the vacuum bag is supported as it fills with heavier material, AND since the typical CV isn't moved (where the bag could become dislodged when being moved) the bag doesn't come off the tube.
I've also found that a slanted bag tube tip is much easier to install the bag than a blunt end which, on occasion, I've witnessed tearing the thin rubber on the vacuum bag.
I'd like to see the combination; a filler bag tube with ridge to move the rubber seal over and with a slanted fill tube.
